Abstract:
In present study theoretical model of MSM energy harvester is discussed and stand-alone energy harvesting device is developed and characterized in the frequency range from 10 to 200 Hz at vibration conditions that are close to real applications. The device utilizes 4 MSM elements (1*2.5*10 mm each) actuated by external mechanical stress that leads to magnetic flux modulation. With external oscillation mechanism the MSM material showed VRMS over 2 V (at 3% stroke, with no resistive electrical load), which is enough for DC rectification. To model real vibration conditions harvester prototype was mounted onto shaking platform with adjustable frequency and amplitude of oscillation. It was found that harvesting productivity strictly depends on mechanical resonance of the oscillating part of the device. Mechanical system improvements allowed achieving maximum power output of more than 38 mW (1 mW • cm-3) at 101 ± 1 Hz.
