Self-powered Bifunctional Sensor Based on Tribotronic Planar Graphene Transistors

Abstract

With the development of material science, micro-nano-fabrication, microelectronics, the higher level requirements are posed on the electronic skins (E-skin). The lower energy consumption and multiple functions are the imperative requirements to spurred scientists and mechanists to make joint effort to meet. To achieve lower energy consumption, a promising energy-harvesting style of triboelectric nanogenerators (TENG) is incorporated into the field effect transistors (FETs) to play the important role for sensor. For bifunctional sensor, to harness the difficult for reflecting the magnitude of frequency, we resorted to synaptic transistors to achieve more intelligentization. Furthermore, with regards to the configuration of FET, we continued previous work: using the electrolyte gate dielectrics of FET - ion gel as the electrification layer to achieve high efficient, compact and extensively adoption for mechanosensation. The working principle of the GFET was based on the coupling effects of the FET and the TENG. This novel self-powered sensor would offer a new platform for lower power consumption sensor for human-machine interface and intelligent robot.

Tribotronic Planar Graphene Transistors for low-energy-consumption high/low frequent stimuli monitoring

“…Recently, based on their previous work [19],writing in Scientific Reports, Yanfang Meng a, b * and Guoyun Gao have been proposed a self-powered bifunctional sensor based on tribotronic planar graphene transistors, which was employed to real-time monitoring with high energy-efficient and 2D imaging [20].…”
