ABSTRACT
This paper presents fully-integrated multi-axis
piezoelectric-on-silicon kinetic energy harvesters (KEHs)
that demonstrate enhanced power output via mechanical
frequency upconversion. Mechanical energy is converted
to electrical energy by out-of-plane and in-plane devices
that are micromachined on the same substrate. The out-of-
plane device demonstrates nearly 100 frequency
