Hybrid energy harvesting from mechanical vibrations and magnetic field

Applied Physics Letters, 2018
This letter proposes a hybrid energy harvesting scheme to collect the energy from mechanical vibrations and the magnetic field simultaneously. The structure consists of a magnetostrictive substrate bonded with a piezoelectric sheet.

The impact of mechanical vibrations on pressure pulsation, considering the nonlinearity of the hydraulic valve

Journal of Low Frequency Noise Vibration and Active Control
The article identifies some of the forces acting on hydraulic valves used in the civil and military vehicles. Particular attention was paid to the single-stage electrically controlled “on/off” hydraulic directional control valve.
