Abstract

Due to the fact that the ambient vibration sources are random and unpredictable, the design of energy harvesters responsing to multi-freuqncy is desirable. In this paper, an array lead zirconate titanate (PZT) thick-film cantilevers were designed and fabricated to demonstrate the possibility of harvesting vibration energy from different frequencies. Two configurations of multi-cantilever were fabricated in a form that elevated from the substrate as free-standing structures. One having six cantilevers of constant width but different lengths and another having five cantilevers of constant length but different widths. The experimental results show a magnitude of voltage at around 70 mV in a range of freqnecy between 220 Hz to 520 Hz which is in a good agreement with simulation results.
