This is a very simple touch sensor switch that is build with the 555 timer IC. You just need to touch the metal plate and the relay gets energised and is kept in this state for about 100 seconds, then ...

A simple four-component circuit allows a single I/O line from any microcontroller to sense the states of two capacitive touch sensors. With so many cell phones, PDAs, and MP3 players using ...

Here is a simple capacitive touch switch circuit for electronics hobbyists. Even though the circuit uses smd components, construction of the touch sensor switch is not very hard because the whole ...

Capacitive sensor technology has evolved markedly over recent years, underpinned by advancements in integrated circuit design and novel measurement approaches. These sensors function by detecting ...

[HankDavis] sent along this link to a video showing a tutorial on how to make touch sensors using a “darlington pair”. In the video we are taken through the idea and how we’re going to construct it.

A water-tolerant design offers a higher level of safety in white-goods applications, and it's cost-effective to boot. Capacitive touch sensors have made homes i n scores of MP3 players and mobile ...

Disney has developed a system for detecting touch using multiple frequencies, which allows gestures to be read on everyday objects, water, or the human body. Disney has developed a system for ...

UniPixel (UNXL) and CIT (Conductive Inkjet Technologies) a subsidiary of Carclo PLC (OTCPK:CCEGF) have entered into a legal dispute. CIT has filed proceedings against UniPixel in the U.K. high court ...
