摘要
Tribotronics,a new field that involves the coupling of triboelectricity and semiconductors,has attracted great interest in the nanoenergy and nanoelectronics domains.This paper proposes a tribotronic bipolar junction transistor(TBJT)that incorporates a bipolar junction transistor and a triboelectric nanogenerator(TENG)in the single-electrode mode.When the mobile triboelectric layer slides on the device surface for electrification,a bias voltage is created and applied to the emitter junction,and then the base current from the TENG is amplified.Based on the fabricated TBJT,a mechanical frequency monitoring sensor with high sensitivity and excellent stability and a finger-triggered touch switch were developed.This work demonstrated for the first time a tribotronic device with simultaneously controlled voltage and current voltage/current simultaneously controlled tribotronic device,which has promising potential applications in micro/nano-sensors,human-machine interactions,intelligent instrumentation,wearable electronics,and other applications.
