Liquid-level sensing based on capacitive sensors comes with its own challenges. It’s like absolute capacitance sensing. Unlike touch detection, the absolute value of the liquid level needs to be ...

As with traditional mechanical switches, a user's interface experience with a capacitive sensor is directly related to the way the sensor responds (sensitivity) upon contact under all operating ...

In industrial automation, sensors form the critical link between machines and their environment, enabling precise control, safety, and efficiency. From inductive proximity to photoelectric and ...

Capacitive sensor technology has evolved markedly over recent years, underpinned by advancements in integrated circuit design and novel measurement approaches. These sensors function by detecting ...

A 3D cage-like flexible capacitive pressure sensor increases its sensitivity as pressure rises, offering tunable performance ...

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 ...

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 sensing ...

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 ...

If you’ve got a smart home, or you just want to know how soaked your garden is getting in the winter, you might want to measure rainfall. There are a bunch of ways to go about it, and this capacitive ...

Densely packed arrays of electrical components called capacitors can form a high-fidelity vibration sensor that can be worn on the skin. Seungjae Lee is in the School of Energy and Chemical ...
