  • Hybrid Magnetic-Ultrasonic Wireless Interrogation of Millimeter-Scale Biomedical Implants With Magnetoelectric Transducer
    Publication number: 20260061202
    Abstract: Embodiments can relate to an implant stimulation and recording system. The system can include a receiver. The system can include an interrogator having a transmitter coil and an ultrasound transducer. The system can include an implant having an integrated circuit and a magnetoelectric transducer. Low-frequency magnetic fields are generated by the transmitter coil and are converted into an electric voltage by the magnetoelectric transducer. Ultrasound energy is generated by the transducer and converted into an electric voltage by the magnetoelectric transducer. When voltage is applied to the magnetoelectric transducer, the magnetoelectric transducer generates magnetic fields and ultrasound waves, wherein the receiver detects the magnetic fields and ultrasound waves generated by the magnetoelectric transducer.
