Secure, wireless, magnetic field system for full body monitoring

UCSD’s Patrick Mercier is developing an ultra low power, wireless, magnetic field system to transmit information through the human body. His goal is a more secure wireless sensor network for full-body monitoring.

Current bluetooth technology uses high-frequency electromagnetic radiation to transmit data.  The signals do not easily pass through the human body, and require additional power to overcome obstruction.

According to Mercier, “This technique achieves the lowest path losses out of any demonstrated wireless human body communication system. It will allow us to build much lower power wearable devices.”
