  text: 'A basic autonomous system powered by a piezoelectric harvester contains three
    components apart from the harvester: a fullwave rectifier, a reservoir capacitor
    and an electronic device performing the primary task of the system. In this contribution,
    a model describing the operation of such a system is derived. It is found that
    in steady-state operation, the piezoelectric harvester experiences two alternating
    load conditions due to the rectification process. These alternating load conditions
    can have a significant effect on the operation of the harvester and must be considered
    in the design of autonomous systems. The results also show that such an autonomous
    system works efficiently if it is connected to a high impedance load and excited
    by a frequency matching the anti-resonance frequency of the piezoelectric harvester.'
