FIG. 1 is a schematic top view of a physiological signal detecting and sending device according to an embodiment of the invention. FIG. 2 is a schematic side view of the physiological signal detecting and sending device of FIG. 1. FIG. 3 is a three-dimensional schematic diagram of the antenna module and the carrier board of the physiological signal detection and transmission device of FIG. 1. Please refer to FIG. 1, FIG. 2 and FIG. 3. The physiological signal detection and transmission device 200 of this embodiment includes a carrier board 210, an antenna module 220, a physiological signal detector 230, a power supply 240 and a wearing part 250. The antenna module 220 is disposed on the carrier board 210 and includes a flexible substrate 222 (also referred to as a flexible circuit board) and a microcontroller 224. The flexible substrate 222 includes a conductive layer, and the conductive layer includes a short-distance communication antenna pattern 222a (for example, a Bluetooth communication antenna pattern). The short-range communication antenna pattern 222a includes a signal-feeding end 222b, a transmitting/receiving wireless signal unit 222c, and a grounding end 222d. For example, the short-range communication antenna pattern 222a, which is a Bluetooth communication antenna pattern, can be based on a frequency of 2.4 GHz and within a range of approximately less than 15 m (for example, a range of less than 6 m can be designed) for wireless signal transmission.

The microcontroller 224 is disposed on the flexible substrate 222, and is electrically connected to the signal feeding end 222b of the short-distance communication antenna pattern 222a. The flexible substrate 222 is bent, so that the transmitting/receiving wireless signal unit 222c of the short-distance communication antenna pattern 222a and the microcontroller 224 are not coplanar and maintain a distance. In this embodiment, the microcontroller 224 is closer to the carrier board 210 than the transmitting/receiving wireless signal unit 222c of the short-range communication antenna pattern 222a. In other words, in this embodiment, the microcontroller 224 is located between the carrier board 210 and the transmitting/receiving wireless signal unit 222c of the short-distance communication antenna pattern 222a.

In this embodiment, the antenna module 220 may further include a short-range communication antenna tag 226 (for example, a near-field communication antenna tag), which is disposed on the flexible substrate 222. The short-range communication antenna tag 226 is not electrically connected to the microcontroller 224, and can maintain a distance from the microcontroller 224 without being coplanar. In this embodiment, the microcontroller 224 is located between the carrier board 210 and the short-distance communication antenna tag 226. For example, the short-range communication antenna tag 226, which is a near field communication antenna tag, may include a near field communication antenna pattern (not shown) and a near field communication antenna chip (not shown) electrically connected to the near field communication antenna pattern. Near field communication antenna tags can be based on a frequency of 13.56 MHz and within a range of approximately less than 50 mm (for example, it can be designed to be less than 10 mm or less than 20 mm) for wireless signal transmission. In another embodiment, the short-range communication antenna tag 226 can be omitted according to design requirements.

The physiological signal detector 230 is disposed on the carrier board 210 and is electrically connected to the microcontroller 224. The physiological signal detector 230 is used to sense the value (such as blood glucose concentration, blood oxygen concentration, etc.), body temperature or heartbeat frequency of a target to be detected in the human blood, as described in detail later. The power supply 240 (for example, a battery) is disposed on the carrier board 210 and is electrically connected to the microcontroller 224. The wearing part 250 is disposed on the carrier board 210 and is, for example, a double-sided tape.

When the physiological signal detecting and sending device 200 is configured on the human body through the wearing part 250, the carrier plate 210 can be attached to the skin of a certain part of the human body, and a member (not shown) of the physiological signal detector 230 can penetrate the human body In the veins. For example, the short-range communication antenna tag 226, which is a near-field communication antenna tag, can communicate with an external reading device (not shown) for wireless signal communication, so that the external reading device can recognize the basic built-in short-range communication antenna tag 226. Data (such as user-related information and desired body parts). Then, the microcontroller 224 can transmit the information (such as blood glucose concentration) detected by the physiological signal detector 230 to the external reading device by means of wireless signal communication through the short-range communication antenna pattern 222a.

Based on the above, the flexible substrate 222 of the antenna module 220 of the physiological signal detection and transmission device 200 of this embodiment is bent, so that the transmitting/receiving wireless signal unit 222c of the short-range communication antenna pattern 222a is different from the microcontroller 224. Coplanar and maintain a predetermined distance. Therefore, when the physiological signal detection and transmission device 200 of this embodiment is configured on the human body, the transmitting/receiving wireless signal unit 222c above the microcontroller 224 can maintain a proper distance from the human body, so that the short-distance communication antenna pattern 222a can be transmitted The energy of the wireless signal received and received during the operation of the wireless signal receiving unit 222c is less absorbed by the human body, and a certain wireless signal transmission performance can be maintained. Therefore, compared with the prior art, the physiological signal detecting and sending device 200 of the present embodiment has better wireless signal transmission performance in use.
