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 ...

Touch sensors have been around for years, but recent advances in mixed signal programmable devices are making capacitance-based touch sensors a practical and value-added alternative to mechanical ...

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 ...

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 ...

A new fabric-based touch sensor used machine learning to control mobile apps, video games and other devices while integrated into clothing. A new study from NC State University combines ...

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 ...
