DARPA ENVision developing next-generation Night Vision Goggles (NVGs) which are compact, multi-band, and wide-FOV

For decades U.S. warfighters have benefitted from advanced night-vision technology, allowing pilots to fly low-level missions on pitch-black nights and ground forces to conduct operations against adversaries in the dark. Traditional Night Vision Goggle (NVG) systems provide the wearer with…...

Nano-opto-electro-mechanical systems (NOEMS)

Modern microelectronic semiconductors and integrated circuits provide remarkable computational and memory capabilities but lack the capability to interface with the physical world directly. MEMS (MicroElectroMechanical Systems) and the even smaller NEMS (Nano ElectroMechanical Systems) integrate sensors and actuators on microelectronic…...

Thermophotonics cooling with light-emitting diodes

Thermophotonics (often abbreviated as TPX) is a concept for generating usable power from heat which shares some features of thermophotovoltaic (TPV) power generation. Thermophotonics was first publicly proposed by solar photovoltaic researcher Martin Green in 2000. However, no TPX device…...
