Your garden variety motion detector uses IR, but these days, there are fancier technologies for achieving similar goals. If so desired, you can source yourself a microwave-based presence sensor ...

Detection using today’s microwave sensors has some advantages. Unlike traditional passive infrared motion sensors, most microwave sensors can distinguish between moving and static objects, and objects ...

Spintronics exploits the intrinsic angular momentum of electrons—their spin—in addition to charge to create devices with novel functionalities. Key building blocks include magnetic tunnel junctions, ...
