Capacitive sensors work by detecting the change of capacitance introduced by the finger touching near the electrode. Such change is so small that detecting it unambiguously is challenging, and has ...

You can’t have a touch sensitive switch without a way to detect the presence of a finger! A touch sensor, especially a capacitive touch sensor, has some surprisingly sophisticated electronics to ...

With the introduction of the first smartphones in 2012 with in-cell touch displays, a battle is emerging between the traditional supply chain of ITO-based touch sensors that are externally combined ...

Infineon has introduced automotive microcontrollers with capacitive touch sensing for sensor and actuator applications. The PSOC 4 HVMS family is built around a 24 or 48MHz Arm Cortex-M0+ processor, ...

To meet the evolving design needs of the diverse and growing market for biometric access control solutions, the globally renowned biometrics company, Fingerprint Cards AB (Fingerprints) has announced ...

Today’s homes and workplaces are increasingly pervaded by smart appliances, which are designed to be attractive and reliable, and ideally should support interactions that are as easy and rewarding as ...

I am trying to test a capacitive touch sensor. Specifically, I want to show that it registers a specific change in capacitance. Capacitance is defined as: C = A * Eo * Er / d Keeping A, Eo and d ...
