Miniaturized magnetoelectric-based wireless bioimplant

Abstract

The present disclosure relates to a magnetoelectric-based wireless bioimplant (MEWB) that can transmit biological activities sensed via a pair of electrodes to an external transceiver by leveraging magnetoelectric (ME) transducer that is coupled to the implant. The MEWB is also capable of wirelessly receiving power and data via the ME transducer from external transceiver when brought closer to the implanted site (e.g., at few centimeters), thus structuring a batteryless and a leadless bioimplant. MEWB may be implanted epidermally through a pair of electrodes on an organ to capture accurate biological activities. The external transceiver may include a transmitter coil for generating an alternating magnetic field and to transmit downlink data and a receiver coil to sense a backscattered field generated by MEWB and to demodulate uplink data. The overall structure of the disclosed implant is adopted enabling compactness, miniaturization (e.g., <3 cm in length and <4 mm in diameter) and endovascular delivery.
