Effect of Heat on the Performance of Novel Energy Harvester by Using PZT-5H Transducers

In this paper the effect of heat on the performance of novel energy harvester (NEH) by using PZT-5H circular transducers was mentioned. PZT-5H circular transducers were heated at three different temperatures such as 200C, 600C and 1000C and tested on 20 g exciter under sinusoidal support excitation by using NEH. The observations were made on three parameters: temperature effect on impedance, temperature effect on resonant frequencies and temperature effect on the output voltage. At 200C, the output voltage is 23 V and at 1000C the output voltage is 18 V is recorded. The observation is that the temperature effects the performance of PZT-5H circular transducers.
