Abstract
The work function energy harvester (WFEH) is a variable
capacitance vibration energy harvester where the charging
of the capacitor electrodes is driven by the work
function difference of the electrode materials. In this
work, we investigate operation modes of the WFEH by
utilizing a macroscopic parallel plate capacitor with Cu
and Al electrodes and varying plate distance. We show
that by charging the electrodes of the WFEH by letting
the electrode plates touch during the operation a
significant output power enhancement can be achieved in
comparison to the case where the electrodes are charged
and discharged only through a load resistor.
