Capacitive touch sensors are based on the electrical capacitance of the human body. When, for example, a finger comes close to the sensor, it creates a capacitance to Earth with a value of 30 to 100 ...

For countless individuals across the globe, Ramadan fasting constitutes a profound and sacred time. However, abstaining from ...

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 ...

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 ...

Electromagnetic interference can screw up cell phone and radio reception. But it may also be the key to cheaply transforming regular LCD screens into touch- and gesture-sensing displays, according to ...

Many robots track objects by “sight” as they work with them, but optical sensors can't take in an item's entire shape when it's in the dark or partially blocked from view. Now a new low-cost technique ...

Researchers have spent years trying to teach robots how to grip different objects without crushing or dropping them. They could be one step closer, thanks to this low-cost, sensor-packed glove. In a ...

Like most of Apple’s new technologies and modern conveniences, Touch ID is something you didn’t know you needed until you got it. As a fingerprint-authorized security sensor embedded in your iPhone 5S ...
