Description/Abstract
This paper describes the development and implementation of an over range protection mechanism which controls the displacement of a kinetic energy harvester when the environmental excitation amplitude increases beyond a maximum tolerable level. This prevents damage to the harvester’s structure due to impact or excessive stress. The control of the displacement is achieved by adjusting the harvester’s resonant frequency to a different frequency than that of the excitation, effectively reducing the mass displacement. This strategy increases the maximum tolerable level of acceleration by 257% from 2.75 ms-2 (rms) to 9.81 ms-2 (rms), in this implementation.
