NTT demoed their human body data transmission technology at CEATEC JAPAN 2004.
The technology detects weak electric fields in a human body by using an optical electric field sensor and provides the data communication speed of about 10Mbps (much faster than 3.7Kbps, the speed Matsushita human data transmission enables.) The system also uses the TCP/IP protocol, making a human body equivalent to 10Mbps ethernet.
