[0057] Experimental Example 1 Electrical Performance Test

[0058] Taking the fabric-based wearable composite energy harvesting device prepared in Example 1 as an example, one end of the exposed carbon fiber of the power generation fiber was connected to an electrometer [Keithley 6514, KEITHLEY, Tektronix Technology (China) Co., Ltd.]. The nanogenerator applies a certain frequency and pressure, and the electrical signal generated is captured by the electrometer and the acquisition card, and then transmitted to the computer through the cable to obtain the open circuit voltage and short circuit current signals. From image 3 and Figure 4 It can be seen that the triboelectric nanogenerator can output a voltage of 140V and a current of 1.95μA.

[0059] The above-mentioned fabric-based wearable composite energy harvesting device was attached to human skin, and one end of the positive and negative wires of the power generation fiber was connected to the positive and negative elec...

Description

technical field [0001] The invention belongs to the technical field of flexible wearable electronic equipment, and in particular relates to a fabric-based wearable composite energy harvesting device manufacturing method and its application. Background technique [0002] E-textile is the integration of multifunctional electronic products into fashionable clothing, which provides a new idea for the further development of wearable electronic products. Among them, the power supply is the foundation and core of realizing such multifunctional electronic textiles. However, traditional bulky batteries powering fabrics are deficient in terms of flexibility, comfort, lightweight and maintenance-free. To address these deficiencies, existing solutions generally integrate fiber power generation devices and energy storage devices into a piece of textile to build a self-charging power system to provide sustainable power for these electronic products. [0003] At present, among numerous p...
