In General > s.a. technology.
* Spintronics: Short for spin electronics, the study of electron spin in materials, with the hope of developing an new microelectronic devices; Based on the belief that up and down spin states can be exploited to build smaller (potentially on atomic scale) binary devices that use less power than charge-current-based devices, which furthermore may also be in intermediate quantum states, which holds the potential for highly parallel quantum computation.

MicroElectroMechanical Systems (MEMS) etc > s.a. casimir effect.
* Idea: Small (microns to mm) electrically-driven mechanical devices.
* Techniques: Surface micromachining (thin films are deposited on a silicon surface and some of the features are etched away to result in movable parts), bulk micromachining (features are carved out of a silicon surface).
* Examples: Sensors (p, a, gyros, imaging, flow), micromotors (inkjet printer jets, valves), mirrors, etc; 1999, Dick Tracy watches by 2005?
* Molecular robots: 1999, T R Kelly built a 78-atom motor [@ Kelly et al Nat(99)sep].

Superconducting and Magnetic Technology > s.a. superconductivity.
* SQUID: A Superconducting Quantum Interference Device for very sensitive measurements of magnetic flux which uses flux quantization and the Josephson Effect, built from 1 (dc SQUID, 1964) or 2 (rf SQUID, 1970) Josephson junctions, operating at a few Kelvins; SQUIDs can measure fields of femtotesla (10–15 T) and monitor the magnetic fields produced by brain activity.
