Wireless Sensors: How Not to Replace 1000 Batteries: Nice brief review of long-lived power sources for sensors, including

  • printed batteries (e.g., Power Paper);
  • extended shelf-life mini-batteries with a nanomaterial called "nanograss;"
  • a nuclear-powered battery that uses a speck of nickel-63 and a tiny cantilever of piezoelectric material (nickel-63 has a half-life of around 100 years)
  • indoor lighting photovoltaics microbattery
  • "strain energy harvesting" using the stretching of piezoelectric fibers
