Magnetically Levitated/Piezoelectric/Triboelectric Hybrid Generator as Self-powerd Temperature Sensing System
The combination of new intelligent materials and structure technology is becoming an effective way in energy havesting and self powered sensing.In this work, we demonstrate a magnetically levitated/piezoelectric/triboelectric hybrid generator, which does not use complex structure.But this hybrid generator has high output power.It includes three parts: electromagnetically levitated generator (EMLG), piezoelectric generator (PNG), triboelectric nanogenerator (TENG).The peak power of each is 135μW, 23mW and 3.6mW, which are obtained at 1MΩ, 10kΩand kΩ, respectively.The output power completely light up LEDs under the vibration frequency of 20 Hz and the vibration amplitude of 10mm.It also can fully charged a 4700 μF capacitor in 13s.On this basis, we have the hybrid generaor itegrated in a self-powered tempreature sensing system which can work stably.The combination of three generators can not only widen the working range, but also increase the working length and sensitivity of the sensing system.This work will extend the application of self-powered sensor in automatic production line and promote the development of industrial control technology.
