I saw the following design concept on Gizmodo today. Intended for use by first responders, the product is made up of (starting upper left and going clockwise) the Paramedic's pad, capsule, electronic band-aid, and personal tag. This page describes each component in detail.

Remember, this is a design concept, not the blueprint for an actual product. The designer, Saravanan Nagasundaram, based his design on research done by Philips and Siemens on molecular diagnostics and miniaturization. Technology used include, “Capillary electro-phoresis (where liquids are decomposed into their component parts in electric
field),bio chips, molecular diagnostics, which will do the analysis
and the data transferred using wireless-lan, blue tooth and infra-red
signals.”

Petty cool.
