Abstract
Piezoelectric vibrational energy harvesters (PVEHs) include a Macro Fiber Composite (MFC)) piezoelectric transducer coupled to a cantilever to harvest vibrational energy. One or more Ionic Polymer Metal Composite (IPMC) strips are situated to provide device tuning over a wide frequency range by applying variable contact force to the cantilever. Power consumption for tuning is sufficiently low that the tuning actuator (IPMCs) can be powered using harvested energy.
