38kbps Multi-Access Magnetoelectric Backscatter Communication with Non-Interrupted WPT for a Network of Miniature Wireless Bio-Implants
This paper presents a time division multi-access (TDMA) magnetoelectric (ME) backscatter communication scheme exploiting the 2<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">nd</sup> resonant frequency of the ME transducer, achieving 1) simultaneous ME uplink and wireless power transfer (WPT) with 38kbps data rate and 0.57nJ/bit energy, doubling the data rate compared to existing ME uplink schemes; 2) A WPT self-interference canceller (SIC), along with an “8” shaped RX coil, reducing interference between TX and RX by 70 dB, assisting backscatter uplink with 7E-6 BER.
