Implant Communication based on 10-60 MHz Band Impulse-Radio Technology
Jianqing Wang, Nagoya Institute of Technology
In view of the requirements for high-speed and highly reliable wireless implant communication, we have developed an implant transceiver working at 10–60-MHz band. The developed transceiver is based on an impulse radio technology with multi-pulse position modulation to increase the communication speed and reliability, and utilizes an automatic equalization technique to suppress waveform distortion and inter-symbol interference due to frequency-dependent tissue properties. The transmit antenna has a dimension in the order of 2 cm and a relative bandwidth of 16% by forming the radiation elements on a flexible magnetic sheet for miniaturization. Through an in vivo experiment on a living swine, we have shown the feasibility of implant communication in a depth up to 26 cm with a data rate of 10 Mb/s. These results demonstrate the superiority of this new technology over all others reported so far in the literature.
