Piezoelectric energy harvesting on a gas turbine implies constraints like high temperature
tolerance, size limitation and a particular range of vibrations to utilise. In order to be able to
operate under these conditions a harvester needs to be small and efficient and to respond to
the appropriate range of frequencies. We present the design, simulation and measurements
for a clamped-clamped coupled piezoelectric harvester with a free-sliding weight which
adds self-tuning for improved response within the range of vibrations from the gas tufbine …
