Article Preview

High output power can be obtained by optimizing the piezoelectric battery structure parameters. Several piezoelectric battery prototypes with dimensions around 30mm×8mm×1mm have been set up to test the power from ambient vibration harvesting. Output power generation of 130 µW at 93.2 Hz is obtained for a typical device with cantilever beam width 8mm. The test results are consistent with the theory analysis and indicate that a piezoelectric battery for ambient vibration energy harvesting is a promising electric power source for wireless sensors nodes with micro-power consumption.
