Description
TEXTILE ELECTRODE AND CONDUCTIVE BUS COLLECTING DATA ON SKIN
TECHNICAL FIELD
The invention relates to an artificial intelligence system integrated with textile-based on-skin data collecting electrode, conductive data transport pathway and loT system.
This invention can serve the medical, medicinal and wellness sectors where rigid electrodes are used extensively, but it is also suitable for use in clothing, sports, home textiles, automotive, space and aviation technologies, internet of things, AR/VR, mobility, smart city systems, gaming I game technologies, virtual universes and defense industry and manufacturing fields where occupational health and safety is a factor.
BACKGROUND ART
With the development of technology, not only computers and smartphones, but also the clothes and accessories we use can turn into smart devices. The fact that user data exchange takes place with smaller devices, mounted on the user's body, provides convenience in many respects. These are called wearable technologies.
Wearable technologies are tools that can be integrated into the human body in different ways by users and are often used as various accessories. These tools, which can also be called wearable computers in the literature, have a structure that creates an almost commensalist relationship between human and computer and enriches the individual's daily life experiences. The wearable technologies include many things from sensor accessories such as smart watches, wristbands, rings and necklaces, to the Google Glass project and its derivative smart glasses, as well as smart optical lenses. Through emerging wireless network technologies, computer processors and smart sensors, most vehicles are connected to each other, search
engines and people. With this Internet of Things dimension, it is obvious that wearable technologies will have an important place in human life.
As mentioned above, dressing, which is one of the basic needs of humanity such as eating, drinking and protection, has given birth to textile products that serve to dress. Since the early ages, textile products have not only been limited to clothing, but have continued to be utilized in the fields of building-construction, agriculture, agriculture, medical, automotive, composite, technical and professional fields with the evolution of technology and comfort needs, as well as in traditional products such as accessories, floor and bed covers, textile surfaces surrounding, covering and upholstering shelters. Throughout the life cycle, people actively or passively interact with textiles in all areas, from the fabric they are bom into to the cloth they are buried with.
Integrating this technology into textile-based products has many advantages. One of the main features of the continuity of textile-based products is that they are suitable for 24/7 use without restricting mobility. During different daily activities, a person can adapt to the environment and activity depending on the comfort properties of the clothing. Instant data measurement is important in protecting the vital conditions of individuals, especially their health status, in emergencies, in times of need. Such an important area needs to be put into service in a way suitable for daily use. Today, smart wearable products (smart watches, smart bracelets, smart glasses, etc.) used for such operations are mostly developed under the accessories segment. One of the reasons for this is that surface electrodes in conventional use cannot be integrated into textile-based apparel in conventional textile manufacturing processes. As a result, inflexible surface electrodes are only used in secondary products such as accessories (smartwatches, wristbands, etc.). Another reason is that gel electrodes can only be used in a hospital setting when the patient is stable and limit the mobility of an individual in daily activity. This type of electrodes or rigid electrodes used in measurements are detached from the user's body when the user moves, such as leans forward, so that bioelectric signals cannot be measured. Furthermore, the user is uncomfortable as these electrodes need to be fixed to the user's body with a flexible material to keep them in contact with the
body. Surface electrodes limit mobility in everyday, high-activity or extreme conditions and impair the standard of comfort in clothing because they are not flexible in material. Furthermore, surface electrodes are not washable. As a result of the researches, it has been determined that the effective, continuous and regular usage life of smart wearable accessories by different user groups is 6 months. For data collection over the body, different surface electrodes need to be placed on multiple different points on the body depending on the type of data to be captured. For example, the electrodes of an electrocardiography sensor need to be placed in a specific location on the body to measure the heart rate variable, whereas the electrodes of a galvanic skin response sensor, which measures emotional sweating, are best measured with electrodes of different structures and placed in different locations on the body.
As regards to loT, it is now an inevitable fact that the use of the internet has significantly changed our daily lives by increasing communication, information sharing and interaction between people. The new technological concept called "Internet of Things (loT)" is defined as the intelligent connection of smart devices through objects that can sense and communicate with each other. With this technology, it is possible to monitor and collect information on almost all events in our environment (home, school, workplace, factory, city, etc.) with a large number of small-sized sensor devices that can use wireless technology.
A sensor, one of the most common concepts in wearable technologies, is a device or organ that detects certain external stimuli and responds in a distinctive way. The electrode and data transfer pathway in the invention acts as an electric charge collector or emitter in a semiconductor device. It is the element responsible for directly transferring a biopotential or skin current to the processor. In other words, this definition establishes an electrical bridge between any configured device (sensor, transducer, cable, etc.) to transmit (transmit and/or receive) a signal between the electronics (of a medical device) and the user (e.g. the user's skin, as referred to in the proposed invention). In this context, only information on wearable electrodes, textile-based electrodes and similar methods and inventions will be shared.

DETAILED DESCRIPTION OF THE INVENTION
The preferred alternatives of the embodiments of invention, which are mentioned in this detailed description, are only intended for providing a better understanding of the subject-matter, and should not be construed in any restrictive sense.
The invention comprises textile electrode(s) (21 ), circuit board (22), power supply (23), conductive bus (24), communication channel (25), cloud (26) and software (27) in an loT system (20) placed on a wearable/dressable product (19).
Any reaction of the body to the outside and any routine or acute vital activity that takes place within the body is reflected as an electrical signal. This signaling infrastructure is reflected on the skin as different conductivity values during response or activity. The invention enables these signals to be detected through the skin and transformed and transmitted into the data to be interpreted by the circuit to which it is connected.
In the invention, the integrated conductive material and the textile electrode (21 ) provide the necessary field for the detection of the instantaneous electrical conductivity difference on the skin. It combines smart textile innovations, clothing experiences and design phenomena with conventional and advanced textile manufacturing techniques to enable the transmission of data to the circuit and processor by connecting the textile electrode (21 ) with the sensor to be included in any smart clothing product, the electronic circuit and processor to which the sensor
is connected via the conductive bus (24) proposed in the invention. The stages of formationof the textile electrode (21 ) and the data transmitting pathway developed with the interdisciplinary approach adopted in the invention, the creation of a data collection area with multi-sensor compatibility for the data to be collected over the skin of the individual and processed in electronic environment, taking into account the conditions of compliance with the comfort and usage conditions that the individual is accustomed to, transporting the data with minimum loss and delivering it to the circuit are followed.
The invention supports the use of wearable or dressable products and surfaces included in the smart category of individuals in continuous contact by combining data collection and transmission with wearability and ease of use, as well as supports the expansion of the usage area of smart technologies by adapting to the psychological and design product usage perceptions and expectations of individuals.
The textile electrode (21 ) and the data transmission pathway form a conductive field with multi-sensor compatibility, enabling the various sensors needed by the circuit for data analysis to receive data from the same field at one time. Examples of compatible on-skin data collection sensors include electrocardiography, galvanic skin response, electroencephalography and electroneuromyography. In addition, it is also suitable for integrating, sensing, measuring, transmitting, interpreting and translating data to collect temperature, pressure, photoplethysmography, stress, magnetic field, electromagnetic force, humidity, accelerometer, gyroscope, proximity, gas, flow, ultrasonic wave, capacitive, activity data within wearable products and dressable surfaces. The data received through the textile electrode (21 ) area and transported via the data conductive pathway can then be converted by the circuit and processor into primary level data such as heart rate, emotional sweating, muscle activation, etc., but also used to generate secondary complex data such as biobehavioral neuro-state monitoring, which involves reading, analyzing and interpreting the primary data. In daily use or in mandatory situations (hospitalization, intensive care, emergency, etc.), continuous or regular sensual contact enables the analysis to take place in any interaction that requires data
analysis without disturbing the comfort and psychology of the individual and without making the individual feel the data analysis. The individual whose momentary comfort is not disturbed can easily continue their daily or essential activities. With the invention, it is aimed to perform unrestricted, uninterrupted, easy and sustainable and high quality data analysis at any condition, situation or time, and to transmit this data to the circuit with minimum loss, to personalize this data with the support of artificial intelligence with loT system (20) integration and to adapt the feedbacks according to the user.

The wearable/dressable product (19) interface is the interface where the loT system
(20) and especially the textile electrode(s) (21 ) and the conductive bus (24) are integrated in order to perform processing steps such as collecting, processing, analyzing, storing, classifying, labeling, and giving feedback on the data to be measured by the user's skin contact. Textile electrode(s) (21 ) can be combined with, but not limited to, woven, knitted, non-woven, 3D-printed textiles, nano-textiles, microencapsulation, shape memory polymer/textile (SMP), bio-textiles, conductive printing, 3D knitting and 3D weaving techniques with conductive material integration using conventional and/or innovative textile technologies. The textile electrode(s)
(21 ) enable the system to perform functions such as data transmission, collection, analysis, classification, labeling, storage, feedback generation, retraining of the model, etc. by transmitting the initial current sent by the circuit board (22) onto the skin and transmitting the new data generated by the conductivity differential (differential difference is only in the case of biosensors and there are different transmission/measurement methods for the detection of additional temperature, pressure, photoplethysmography, stress, magnetic field, electromagnetic force, humidity, accelerometer, gyroscope, proximity, gas, flow, ultrasonic wave, capacitive, activity data) difference in the skin back to the circuit board (22) via the conductive bus (24). Textile electrode(s) (21 ) are parts integrated into a washable, wearable/dressable product (19) suitable for daily use, which function as receivers to perform data processing without causing discomfort to the wearer in measurements requiring continuous skin contact. In this way, the system can continuously and constantly carry out data collection and processing steps with minimal loss without disturbing the user. Textile electrode/electrodes (21 ) have a uniform receiver feature that is adaptable for various and multiple sensor types such as ECG - electrocardiography, GSR- galvanic skin response, EMG- electromyography/electroneuromyography, EEG- electroencephalography, temperature, pressure, photoplethysmography, stress, magnetic field,
electromagnetic force, humidity, accelerometer, gyroscope, proximity, gas, flow, ultrasonic wave , capacitive, activity, in this way, loT system (20) measurements and bodily data analysis can be performed simultaneously in a single step without the need for different electrodes of different structures on the wearable/dressable product (19). The conductive bus (24) is responsible for data transportation by enabling communication between the textile electrode(s) (21 ) and the circuit board (22) and can be combined with, but not limited to, woven, knitted, non-woven, 3D- printed textiles, nano-textiles, microencapsulation, shape memory polymer/textile (SMP), bio-textiles, conductive printing, 3D knitting and 3D weaving techniques with conductive material integration using conventional and/or innovative textile technologies. The conductive bus (24) is integrated on the wearable/dressable product (19) and acts as a transmission bridge that is washable and best suited to the individual's daily wearing comfort without slipping and non-contact. The first current sent by the circuit board (22) via the conductive bus (24) to the textile electrode(s) (21 ) detects the differential difference (it is only for biosensors and there are different transmission/measurement methods for detection of temperature, pressure, photoplethysmography, stress, magnetic field, electromagnetic force, humidity, accelerometer, gyroscope, proximity, gas, flow, ultrasonic wave, capacitive, activity data) of the conductivity change on the skin. As a result of the first current returning to the circuit board (22), the conductor difference is analyzed by the software (27) embedded in the circuit board (22). The software (27) is a code system with cloud (26) system integration, artificial intelligence and/or machine learning features, taking the features such as desired feedback, communication channel (25) features and data quality into account. The software (27) and the cloud (26) work together, and data transfer to the cloud (26) is done via channels such as existing loT routing protocols bluetooth, WiFi, RF, BLE, cellular, LoRa, LoRaWAN, LWM2M, NFC (near field communication), Sigfox, Wi-Sun, ZigBee, Z-wave, MQTT (message queued telemetry transfer), AMQP (advanced message queue transfer), HTTP (header text transfer protocol), CoAP (Constrained Application Protocol), DDS (Data delivery service), WebSocket, XMPP (Extensible Messaging and Presence Protocol), OPC UA (OPC unified architecture). When performing functions such as data analysis, classification, labeling, responding, etc., the software (27) uses public and/or individual user data
previously stored in the cloud (26) to improve the quality of analysis. The software (27) also trains and models itself with the newly acquired data to update the data scale, increase accuracy and store the new data in the cloud (26). The software (27) embedded in the circuit board (22) transmits data feedback to the board. The circuit board (22) communicates the communication solution selected according to the incoming data between the systems via the communication channel (25). These communication methods include speech channels and protocols between Internet of Things objects such as bluetooth, WiFi, RF, BLE, cellular, LoRa, LoRaWAN, LWM2M, NFC (near field communication), Sigfox, Wi-Sun, ZigBee, Z-wave, MQTT (message queue telemetry transfer), AMQP (advanced message queue transfer), HTTP (supertext transfer protocol), CoAP (Constrained Application Protocol), DDS (Data delivery service), WebSocket, XMPP (Extensible Messaging and Presence Protocol), OPC UA (OPC unified architecture). The communication channel (25) contains these speech channels and also transmits the desired feedback to the selected response interface (28). The response interface (28) includes, but is not limited to, product systems such as any loT device, computer, smart products, etc. The loT system (20) can contain, as well as can report and give feedback on the user's physical data. A function loop is completed when the loT system (20) transmits the last selected response by the communication channel (25) to the response interface (28). The system starts the cycle of re-measurement, analysis and response by providing the first current at any time and in cases where continuous and regular measurement is required, aiming to evaluate bodily data changes quickly and with minimal loss.
The invention is still included in the category of passive smart textiles and can be used (including but not limited to) in electronic and software systems to measure, evaluate and report data. In the next step, it is aimed to develop the invention to be included in the category of active smart textiles (Active smart textiles are textiles that can sense and report changes in the external environment) and then high smart textiles (Highly intelligent textiles are textiles that can sense and respond to changes accordingly in the external environment or adapt and change their function in response to a user input). In this way, it is planned to embed electronic components into the textile electrode (21 ) and transform it into a codable material,
and the hardware and software will be completely realized on the invention. It is also expected to combine the material with different advanced production techniques. Techniques such as shape memory polymers, 4D printing technology (not limited) can be used that can be adapted for use in textiles in the future.
