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 ...

The model 720 is a low-cost, compact capacitance vacuum gauge (CVG) based on the companyÕs variable capacitive sensor design. It produces a 0 to 5 Vdc or 0 to 10 Vdc output that is linear with ...

This article provides an overview of capacitive touchscreen technology and describes the challenges inherent in implementing this technology in handheld devices. Ever since Apple launched the iPhone ...
