Abstract

Abstract: Rapid development in flexible and stretchable electronics poses the challenge for stretchable and multifunctional power devices. Here, we firstly report a fully-transparent and stretchable triboelectric nanogenerator (EC-TENG) based on edible grade silica gel (EGSG) and crystal mud (CM) to enable both biomechanical energy harvesting and human posture sensing. And We also invert a novel Na-ion battery based on FeSe2, which can realize the efficient storage of micro-electric energy. Under the hand with nitrile glove pressing frequency of 5 Hz, the short-circuit current ( I sc ), open-circuit voltage ( V oc ), and transfer charge of EC-TENG can reach 25.96 µA, 1400 V, and 150 nC, respectively. The maximum output power of EC-TENG can reach 7.84 mW with a match load of 40 MΩ. The EC-TENG device exhibits excellent stretchability and deformability under extreme conditions, including foldability, stretchability, distortion, and washability. Significantly, the EC-TENG can generate electricity by deforming itself and under non-contact conditions after friction with other triboelectric materials. From the experimental results, the EC-TENG can charge the Na-ion battery to 3 V in 13 h, and the electrical energy stored in the Na-ion battery can drive the temperature/humidity sensor. This design achieves the integration of power generation devices, sensor devices, and energy storage devices, and it will promote the development of all-in-one self-powered flexible wearable electronics.
