This paper deals with energy harvesting from mechanical energy of an ambient vibration. The ambient vibrations are inexhaustible suitable source of energy for feeding wireless sensors in aeronautical applications. The electrical power is generated from an ambient mechanical vibration by use of a vibration power generator. This generator shows an alternative for supplying wireless sensors. The vibration power generator consists of a resonance mechanism, magnetic circuit and a coil. The construction of the resonance mechanism is tuned up to the resonance frequency and acceleration of the excited vibration. As the generator is excited by ambient mechanical vibration, the resonance mechanism produces a relative movement of the magnetic circuit against the fixed coil. This movement induces a current into an electrical coil due to Faraday's law. The harvested power depends on the excited vibration, proof mass of the generator, quality of the resonance mechanism, coil construction and a connected resistance load. For aeronautical applications, e.g. helicopters, the generated power of around 5mW provides enough energy to supply a wireless sensor.
