This paper deals with an energy harvesting system for avionics; it is an energy source for a unit which is used for
wireless monitoring or autonomous control of a small aircraft engine. This paper is focused on development process of
energy harvesting system from mechanical vibrations in the engine area. The used energy harvesting system consists of
an electro-magnetic energy harvester, power management and energy storage element. The energy harvesting system
with commercial power management circuits have to be tested and verified measured results are used for an optimal
redesign of the electro-magnetic harvester. This developmental step is necessary for the development of the optimal
vibration energy harvesting system.
The aim of this paper is to examine the performances of thermoelectric generator based on microelectromechanical
systems technology (MEMS) in wide range of operational conditions. The goal is to evaluate capability of this
technology for a development of an independent energy source for aircraft applications. Complex overview of MEMS
TEG properties obtained by computational modeling, simulations and experimental testing is utilized to define critical
phenomena of MEMS TEG technology.
