Abstract
In this work we present a wireless, energy harvesting powered solution for vibration analysis. In order to ensure minimal power consumption the system is equipped with our own radiofrequency protocol, which is tailored for the needs of energy harvesting.Our system has a small form factor, all the while containing everything needed for a wireless energy harvesting sensor unit. It has two switchable MEMS accelerometers to ensure minimal power consumption and to maintain wide frequency range if needed. The on-board processing unit with floating point hardware accelerator makes Fourier transformation, thus vibration spectrum analysation efficient. The energy management unit is designed with dual topology, making it able to accept both low and high impedance energy harvesters at the same time (hybrid harvesting). The radiofrequency module may work with our own radio frequency protocol or with the Bluetooth standard (Bluetooth 5, BLE with long range PHY).
