Macroscopically, capacitive sensors are usually analyzed by converting their capacitance into another physical variable, such as voltage, time, or frequency. Microscopically, capacitive sensors have ...

Capacitive proximity sensor block diagram Capacitive proximity sensors use two metal electrodes or plates to generate a high-frequency electrostatic field.

Capacitive sensing is a contactless-sensing technique with numerous applications, ranging from proximity sensing (Fig. 1), gesture recognition, automotive rain sensors, and remote liquid-level ...

Proximity sensors sense the proximity of a conductive object. For many applications, we are particularly interested in sensing human hand/fingers. There are different technologies to implement ...

Using precision additive printing, a research team has devised a battery-free inductive, implantable stent for monitoring blood flow that can be read non-invasively.

Abstract: This study proposes a new wireless skin moisture detection system using a capacitive sensor rather than traditional optical methods. Moisture is the most important factor for maintaining ...

In this article, an equivalent conversion between eddy current (ECT) sensor topology circuit and piezoelectric crystal topology circuit is proposed. Based on this conversion, a novel multiparameters ...
