A: Well, there are a myriad of technology surprises sure to be had in this symposium, but the one surprise that truly shocked me is the presentation in which Professor Patrick Mercier (UC San Diego Electrical Engineering department) discusses how the energy gathered from the sweat from one-square centimeter of skin can actually run a radio (sensor). And it is used to transmit information about the health of your body! That's something I thought I'd never see -- sweat energy used to diagnose and transmit the state of health of the human body. And from such a small area -- about the size of a US nickel. You have got to admit, that's a truly surprising technological advance.
