Heartbeat Sports Bra
Numetrex has released a great device for female runners, a sports bra that monitors your heartbeat. The fabric is made by Textronics, and is similar to Lycra. With the transmitter and watch, it retails for $115, and can be bought off their website.
Another similar company, Eleksen, is producing fabric that can transmit electricity without wires. I'm going to be reviewing an iPod jacket from them next week here on igargoyle.
