A memristor is a two-terminal electronic device whose resistance can be precisely controlled by the application of an external voltage or current. The memristor was first proposed in 1971 by Leon Chua, who predicted that memristors would one day play… Read More

Loud speakers are devices that amplify sound to a level that is audible to the human ear. They are used in a variety of applications, such as in public places such as stadiums and arenas, in home theaters, and in… Read More

A liquid crystal tunable filter (LCTF) is an electro-optical device that uses the unique properties of liquid crystals to selectively filter a specific wavelength of light from a broadband light source. LCTFs are used in a variety of applications, including… Read More

A laser diode is a semiconductor device that emits light when an electrical current is passed through it. Laser diodes can be used to create both visible and invisible light. Some laser diodes emit light in the ultraviolet (UV) range,… Read More
