Abstract:
Autonomous sensors based on vibrational energy harvesting offer a maintenance-free solution for wireless sensor nodes. In this paper, we use lead-free and nontoxic piezoelectric materials to power up ultra-low-power management IC board. The advantage of this lead-free technology is an install-and-forget device in practically any application where vibration energy is available. The focus of this paper is to use the frequency of Bluetooth emission as a function of acceleration amplitude as a sensor of resonant vibrations.
