Bistable Electromechanical Receiver For Ultra-Low Frequency Wireless Power Transfer
Récepteur électromécanique bistable pour le transfert d'énergie ultra basses fréquences
Résumé
In this article, we investigate a nonlinear electro mechanical receiver for transmitting power with ultralow frequency magnetic fields (110 Hz). The proposed nonlin ear receiver is based on a bistable buckledbeam resonator that exhibits promising energetic behaviours when excited at ultralow frequencies. After a numerical study of the re ceiver 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 Hz).
