Bistable Electromechanical Receiver For Ultra-Low Frequency Wireless Power Transfer

In this article, we investigate a nonlinear electro-mechanical receiver for transmitting power with ultra-low frequency magnetic fields ($1-10 \text{Hz}$). The proposed nonlinear receiver is based on a bistable buckled-beam resonator that exhibits promising energetic behaviours when excited at ultra-low frequencies. After a numerical study of the receiver dynamics, an experimental prototype has been tested to validate the proposed concept. We demonstrate a transmitted power of 5.6 mW with a magnetic field frequency of $(1 \text{Hz})$.
