Here is a great collection of touch switch circuits. A touch switch is an electronic device that enables us to control a circuit by simply touching a sensor. Simple touch switch circuit with 4011 – ...

The transistor laser invented by scientists at the University of Illinois at Urbana-Champaign has now been found to possess fundamental non-linear characteristics that are new to a transistor and ...

Transistors, the tiny switches that flip on and off inside computer chips, have long been the domain of electricity. But scientists are beginning to develop chip components that run on light. Last ...

An electrical switch made from conductive wood could become a building block for future electronic devices embedded within living trees and other plants. “There is an emerging research field called ...

A special type of matter called a Bose-Einstein condensate could be used to make tiny atomic transistors, according to research carried out by physicists in the US. The result is a first step in ...

A load switch is an electronic switch. It works like a relay to power supply rails in systems, but it has no moving parts. Load switches are increasingly found in today’s portable electronic devices, ...

Every rose has its thorn – but roses grown in a Swedish lab have transistors and electrodes too. Researchers at Linköping University have created bionic roses by incorporating plant-compatible ...
