Hydrogel-based hierarchically wrinkled stretchable nanofibrous membrane for high performance wearable triboelectric nanogenerator

The rapid development of stretchable and multifunctional electronic technologies has created a need for power supplies that have comparable stretchability, durability, and functional variety. Herein, we report an easy-to-fabricate, high-performance, and wearable triboelectric nanogenerator (TENG) constructed on a hydrogel-based hierarchically wrinkled stretchable electmspun nanofibrous membrane for effective energy harvesting from human movement. The approximate output voltage and current from the TENG device reached 270 V and 11 mu A, respectively. The TENGs are capable of harvesting energy from typical human motions (stretching, bending, and twisting) and meet the requirements of commercial electronic devices. Combined with a Bluetooth module, the device could be used as a real-time energy management monitoring system. This work presents an innovative technology for fabricating high-performance stretchable power sources that show tremendous potential in wearable applications.
