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 ...

• Trapped acoustic resonance is most simply described with an analogy: the ringing of a bell. • Microprocessors control the frequency of the mechanical resonance and monitors its decay. • A thicker ...

Promising to make mobile devices more user-friendly and energy-efficient, the SFH7740 and SFH7741 surface-mount proximity sensors use distance measurements to detect a device’s operating status ...

AKM unveils AK4160, a Low Power 16-channel Capacitive Touch Sensor IC. AK4160 is a low operating voltage and low power consumption 16-channel capacitive touch sensor. The device has a channel ...

Capacitive touch sensors are entirely in the domain of DIY, requiring little more than a carefully-chosen conductive surface and a microcontroller. This led [John Phillips] to ask why not embed such ...

Apple is examining a shift from a force sensor in AirPods to a capacitive touch system to make a set easier to control, and provide new options. The latest in Apple's surprisingly long history of ...

After announcing the new ICS-powered Xperia lineup last month, Sony shared some details today on the new sensor-on-lens touch screen tech being built into the Xperia V. Sony described the tech as ...

Touchscreens and multitouch technology make up a significant majority of Apple's research into future user interface improvements, and the iPhone introduced some of those UI paradigm shifts into our ...

Researchers at Carnegie Mellon University have created a new way to turn almost any surface into a touchpad with just a little conductive spray paint. The system, called Electrick, uses a technique ...
