Thrilled by the idea mentioned in “When Things start to think” by Neil Gershenfeld i started to build a near-field intra-body communication device to transmit data through a body by capacitive coupling.
Original paper by Thomas Guthrie Zimmerman: http://www.cba.mit.edu/docs/theses/95.09.zimmerman.pdf
Using the body as a communication channel is an interesting approach to send sensors-data from one part of the body to another part of the body – or to another body. This may be very useful for e-textile projects. Especially when it is not possible to use conductive material to transmit data.
