In electrical engineering, capacitive sensing (sometimes capacitance sensing) is a technology, based on capacitive coupling, that can detect and measure anything that is conductive or has a dielectric constant different from air.

Capacitive sensing is becoming a popular technology to replace optical detection methods and mechanical designs for applications like proximity/gesture detection, material analysis, and liquid level sensing.

Mar 17, 2025 · What is a capacitive sensor? A capacitive sensor is an electronic device that can detect solid or liquid targets without physical contact. To detect these targets, capacitive sensors emit an electrical field from the sensing end of the sensor. Any target that can disrupt this electrical field can be detected by a capacitive sensor.

Luckily, you'll have this this handy guide to help you on your road to becoming a capacitive sensei. Here you'll find a bunch of guides, tips, tutorials and general information about this unstable and strange sensor technology.

cap will sense object position anywhere near the sensing line or electrode. § Self-cap is generally better for sensing proximity of nearby objects. § Self-cap is sensitive to parasitic capacitance to ground.

Capacitance sensors are an emerging technology for human-machine interfaces and are rapidly becoming the preferred technology over a range of different products and devices. Capacitance sensors enable innovative yet easy-to-use interfaces for a …

Learn how capacitive sensors are used for industrial applications. See examples of capacitive sensors that help to measure appropriate thickness, gap, and displacement.

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 switches in a wide range of consumer products.

Capacitive sensing is the process of detecting a change in an electrical property of a dielectric material by measuring changes in capacitance. It is a non-contact method of sensing; thus, it does not require any mechanical parts or parts that would require contact with …
