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 ...

Abstract: This article presents a new capacitive flow sensor intended for industrial fluid flow measurement. The sensor has a U-tube structure and relies on the centrifugal and momentum forces that ...

Abstract: This research presents an efficient front-end circuit for grounded capacitive sensors (GCSs), based on a phase-locked technique. An all-pass filter serves as a phase shifter to obtain the ...

What is part way between a printed circuit board and a rats-nest of point-to-point wiring? We’re not sure, but this is it. [Johan von Konow] has come up with an inspired solution, 3D printing an ...

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 ...
