1. Introduction
The growing need for alternative and portable sources of
energy has motivated significant effort to develop new forms
of energy-conversion and storage devices.[1­5]
The capability
of harnessing various forms of ambient energy present in the
environment (e.g., mechanical vibrations, heat, water flow,
wind, and human activities)[6]
is an attractive feature for such
energy-conversion devices. Powering small electronic devices
with energy harvesters would make them independent of
external power sources, which are generally bulky and expen-
sive. Ambient energy is mostly dominant in the mechanical
