Abstract
The self-powered sensors developed by us can function without external power supply. By directly converting mechanical energy or thermal energy into electric outputs, the output values of the developed sensors will be varied upon the sensing of target biomolecules or metal ions. With the simplicity, low-cost fabrication and label-free sensing mechanism, the developed self-powered sensors demonstrate great potential to serve as new prototypes of portable devices for the onsite sensing of samples. And as far as the development of wearable electronics is concerned, power supply has always been the bottleneck to overcome. We also utilized commercial textiles and proteins/hydrogels to fabricate biocompatible, portable, and lightweight generators to harvest biomechanical energy from human motions or thermal energy from body heat in the environment to directly power wearable electrochemical systems for humidity/temperature/sweat detections (ions, glucose, and lactate) and antibacterial applications. The developed wearable systems also show their adaptability to be integrated with next-generation smart textiles.
