Where to Tap the Power Caution: Thad’s numbers tend to be optimistic! Watt-level available Thad Starner, Human-Powered Wearable Computing, IBM Systems Journal 35, pp. 618-629 (1996).
In Vivo Fuel Cells Adam Heller, UT Austin • Extrapolating from electrochemical detection of glucose (TheraSense) – Adapt techniques for more power – Make a sugar-burning bio fuel cell • Composite electrodes and conductive gels – Biologically transparent system – Build into a vascular stent – Generate electricity from glucose and O2 in blood • 1 cm long x 4 mm wide • Can (theoretically) produce up to 1 mW – 1-3 weeks of power from equal-size battery • 1-2 μW for 1 week at a 0.5 V demonstrated in 2002 (in a grape) • US Patent 6,531,239 • In-vitro low power or low duty-cycle medical systems – Low-bandwidth biosensors – Valve for the incontinent
