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 ...

[CNLohr] has been tinkering with some fun parts of late. He’d found out that ordinary LCD screens could be used as simple touch sensors, and he had to try it for himself. He ended up building a little ...

Using a 3D-printed material sensitive to electric fields, researchers have created a novel sensor that can accurately recognize and distinguish objects up to 10 centimeters – about four inches – away ...

[Andrew] recently got the authorization to install Linux on his work PC, and he was looking for a way to control his music without relying on keyboard shortcuts to do so. Additionally, he wanted an ...

Capacitive touch sensors have made homes i n scores of MP3 players and mobile phones. Of course, the mobile arena is no longer the only bastion for these devices. Today, sensor technology has ...

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 ...

Inexpensive silicon rubber composites used to make robotic skin host an insulating layer which prevents direct electrical contact, making accurate and repeatable measurements virtually impossible. Low ...

Charge transfer minimizes sense-plate count. Evaluation kits speed robustness and ease-of-use assessment. While electronics engineers struggle to embed more functions into ever-shrinking size and ...

Researchers have developed a flexible optical touch sensor that can simultaneously detect the strength and location of pressure with high sensitivity and stability. The advance in tactile sensing ...
