Transduction involving the conversion of energy from one form into another is common in many military and space devices, such as communications antennas (radio waves to electrical signals), thermoelectric generators (heat to electricity) and electric motors (electromagnetic to kinetic energy). Research efforts to develop new transductional materials, however, have largely been limited to laboratory demonstrations and haven’t always resulted in new capabilities or significant size, weight, and power (SWAP) reduction for military devices and systems.
Unlike photonic sensors that exploit the photoelectric effect to enable infrared imaging at cryogenic temperatures, uncooled thermal sensors work by allowing an infrared absorbing material to be heated by incident electromagnetic radiation to produce an image. Such thermal sensing devices, also known as bolometers, have traditionally been less sensitive and slower than their cooled photonic analogs.
