Description
Technical Field
The invention belongs to the technical field of flexible wearable electronic equipment, and particularly relates to a manufacturing method and application of a fabric-based wearable composite energy collecting device.
Background
Electronic textiles integrate multifunctional electronic products into fashion clothing, and provide a new idea for further development of wearable electronic products. Wherein, the power supply is the foundation and the core for realizing the multifunctional electronic textile. However, conventional heavy batteries that power fabrics are deficient in flexibility, comfort, light weight, and maintenance-free. In response to these deficiencies, existing solutions generally integrate fiber power generation and energy storage devices into a textile, creating a self-charging power system to provide sustainable power for these electronic products.
Currently, among many power generation devices, a triboelectric nano-generator (TENG) has proven to be an effective technique for capturing low frequency human motion energy. Because TENG has the advantages of simple structure, wide choice of materials, low cost, etc., and is easily designed into textile fabrics.
Meanwhile, it is worth noting that human sweat is also an energy source, because the content of organic lactic acid in sweat is high, and lactic acid can be used as a raw material of a biofuel cell to generate electricity. Currently, existing biofuel cells are designed with an external structure, mainly a serpentine structure, which may give the person an uncomfortable and airtight wearing experience, since the elastic base of such a structure is usually waterproof. While the fiber-based biofuel cell can be integrated into a multifunctional textile by sewing or weaving techniques without affecting the stretching ability and air permeability of the device. Based on this, there is a need to develop a fabric-based composite energy collection device that is comfortable to wear and can simultaneously collect human body movement energy and sweat bioenergy.
