Abstract

We present a two-stage energy extraction circuit for a piezoelectric energy harvester,
powering an asset-tracking system. Exploiting non-sinusoidal accelerations generated by many
logistic transport devices, e.g., pushcarts, forklifts, assembly belts or cars, we are able to harvest
sufficient electrical energy to transmit radio signals, which will allow to track the object when it is
moving. By using the proposed energy extraction circuit, the energy extraction efficiency could be
improved by at least 30% compared to a single-stage solution for sinusoidal excitations. In the
practical use-case, the two-stage energy extraction network performs more than four times better
compared to the single staged on.
