Wireless sensing using vibration energy harvesting micro-generators

02 October 2006

Following the launch of a vibration energy harvesting micro-generator by Perpetuum in June this year, the company has announced a new version of the device designed for use on helicopters. The PMG27 harvests the vibration induced by the rotor to generate electrical power, enabling complete wireless transmission systems incorporating sensors such as those used in health and usage monitoring systems, to be installed without need for batteries, expensive cabling or maintenance. New sensors can thus be installed at very low cost, without wiring and without the associated paperwork.
