This paper reports the design, optimization, and test results of a mechanical amplifier coupled to an electromagnetic energy harvester to generate power from lowamplitude (±1 mm) and low-frequency (<5 Hz) vibrations in the presence of large static displacements. When coupled to a translational kinetic energy harvester, the amplifier boosts small vibration amplitudes by as much as 4x while accom...

Vibrational energy harvesters can exhibit complex nonlinear behavior when exposed to external excitations. Depending on the number of stable equilibriums, are defined and analyzed. In this work, we focus bistable harvester with two wells. Though there have been earlier discussions such harvesters, all these works periodic Hence, focusing our analysis both quasiperiodic forced harvesters. Variou...

This paper reports a novel technique enabling to tune the resonant frequency of linear inertial piezoelectric energy harvesters through the control strategy of the associated electronic interface circuit. When associated with piezoelectric devices exhibiting high electromechanical coupling, it is expected to enable the variation of the resonant frequency in large proportions.

This paper reviews the state-of-art of the subthreshold level design energy harvesters for powering biomedical implants. Power consumption and lifespan are crucial requirements for the electronic circuitry of implantable systems. In order to meet these challenging requirements, a design for an energy harvester that operates in a subthreshold level offers a promising solution.
