Rolling Rod Electrostatic Microgenerator

Electrostatic wear monitoring of rolling element bearings

Research and development work at the University of Southampton using an electrostatic condition monitoring system developed by Smiths Aerospace Information Systems has shown that electrostatic charge signals can be used to detect the onset of wear in lubricated tribo-contacts. Preliminary investigations have already demonstrated the viability of this system when tested on a laboratory-based pin...

Reeling Mechanism for Wire Rod Rolling Mills

Single-Capacitor Electret Impact Microgenerator

A new type of electrostatic microgenerator is presented that converts mechanical microvibrational energy into electric energy. The energy conversion mechanism is as follows. External microvibrations are transmitted to the device frame. The thin electret layer sputtered to the silicon substrate surface was fixed on the frame and the moving electrode was fixed by a weak suspension and comes into ...

Energy Harvesting Technologies: Thick-Film Piezoelectric Microgenerator

Development of a rotary electromagnetic microgenerator

This study presents the development of an in-plane rotary electromagnetic microgenerator, which consists mainly of a multilayer planar copper (Cu) microcoil and a multipolar hard magnet made of NdFeB, the whole volume of which is approximately 5 × 5 × 2 mm3. The study focuses on the design and manufacturing required to obtain a high power generation output, and an analytical model is developed ...
