PI (Physik Instrumente) offers a new brochure on capacitive nanometrology displacement sensors and signal conditioning electronics. The brochure presents PI’s sensor systems and also features a ...

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 ...

A finger-heating effect has been observed on mutual capacitive touch sensors with plastic film overlay. The symptom is exhibited as serious sensitivity degradation when there is a greater than 10°C ...

The brochure on capacitive nanometrology displacement sensors and electronics presents PI’s state-of-the-art systems and also features a tutorial on single plate and dual plate capacitive sensors and ...

Depending upon the distance between the surface of a capacitance probe and a target source, the electrical capacitance that is formed between these two objects will vary. In an effort to improve ...

Most proximity sensors use an electromagnetic field to sense the presence of a target metal. But there are times when it's necessary to sense nonmetallic materials such as plastics, liquids, or ...

Tick tracer. Glow meter. Sniffer. They go by many names, but capacitive voltage sensors are all designed to do one thing: detect the presence of voltage in a wire or piece of equipment without ...

A new teardown published on iFixit, which focuses on the display of the iPhone 6s, has revealed the components that are thought to provide its 3D Touch feature. 3D Touch allows the iPhone’s ...

From synchrotron light sources to long-term space missions, nanopositioning specialist Queensgate is eyeing niche markets and extreme operating conditions for its NC series of nanosensors Tough enough ...

In the last Sensor Sense we looked at capacitive touch switches used for on/off control. But these switches are also found in capacitive touch sliders that can control various levels, such as volume ...
