A Double-Helix-Structured Triboelectric Nanogenerator Enhanced by Positive Charge Traps for Self-powered Sensing and Smart-Home Control System

Abstract

Triboelectric nanogenerators (TENGs) has been in the public spotlight for their amazing capability on driving miniature electronics. Here, we report a sophisticated double-helix-structured triboelectric nanogenerator (DHS-TENG) enhanced by positive charge traps for self-powered sensing and smart-home control system. The DHS-TENG increases the charge density on the contact surfaces by taking the advantage of ferroelectric characteristics of polyvinylidene fluoride (PVDF), and the flexible double-helix-structure features its excellent elastic property for it has no external support materials. The reported DHS-TENG can deliver a peak output power of 9.03 mW under a loading resistance of 4 MΩ with the dimensions of 3 cm × 3 cm × 5 cm and a light weight of 10 g as well as get an enhanced output performance of 460 V, 140 μA and 400 nC under a constant contact force of 40 N. Furthermore, the DHS-TENG is capable of powering 120 green LEDs and a temperature sensor as well to work properly. Especially, the DHS-TENG demonstrates its capability on remote data transmission for smart-home control system application within 10 meters successfully.
