Wireless vibration harvesting system for turbine engines
Journal Title: Jurnalul Stiintific TURBO - Year 2018, Vol 5, Issue 1
Abstract
The article presents the operation and testing of a vibration energy harvesting system with a piezoelectric harvester and wireless sensor data transmission. Conceiving a system that not only includes vibration harvesting on a turbine engine but also a wireless instrumentation node, is a matter of insufficient development maturity within worldwide research area. Within this paper, we proposed and tested, in the lab and on a turbine engine, an architecture for an autonomous instrumentation system, with wireless communication and powered by energy from vibration.
