According to recent research published in the journal IEEE Transactions on Ultrasonics Ferroelectrics and Frequency Control, "In this study, we report results on a piezoelectric-material-based mechanical energy-harvesting device that was fabricated by combining laser machining with microelectronics packaging technology."
"It was found that the laser-machining process did not have significant effect on the electrical properties of piezoelectric material. The fabricated device was tested in the low-frequency regime of 50 to 1000 Hz at constant force of 8 g (where g = 9.8m/s(2))," wrote H. Kim and colleagues, University of Texas.
The researchers concluded: ...
