Energy harvesting technology provides a promising choice to replace the batteries used in modern wearable devices. This paper describes new kind of piezoelectric energy harvesting devices aiming for high power output at low frequency with broad bandwidth. By accessing the performance of the device at different frequencies, we have demonstrated two energy harvesting devices with power output at 10 microwatts level. A complete energy harvesting system is also designed to adjust the output voltage… CONTINUE READING
