a) Wireless cardiac sensing using ME backscatter uplink. Right inset: a packaged ME cardiac sensor is shown next to a pencil to demonstrate the device size. b) Illustration of magnetoelectric backscatter communication uplink using a magnetoelectrics transducer that combines a magnetostrictive layer(Metglas) and a piezoelectric layer(PZT-5). The transducer is excited using a magnetic transmitter coil TX that generates a pulsed magnetic field. Upon excitation, the ME transducer generates a backscattered field that is detected using a magnetic receiver RX.
