Abstract—Self-powered microsystems like wireless microsensors
and biomedical implants derive power from in-package minibat-
teries that can only store sufficient energy to sustain the system for
a short life. The environment, however, is a rich source of energy
that, when harnessed, can replenish the otherwise exhausted bat-
tery. The problem is harvesters generate low power levels and the
electronics required to transfer the energy to charge a battery can
easily demand more
