Arduino has just announced the Arduino Matter Discovery Bundle (AKX00081), an all-in-one development kit designed to help ...

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 ...

Light aircraft often use a heading indicator as a way to know where they’re going. Retired instrumentation engineer [Don Welch] recreated a heading indicator of his own, using cheap ...

These days, photochromic lenses are old-hat. Sure, it’s useful to have a pair of glasses that automatically tints due to UV light, but what if you want something a little more complex and flashy?

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 ...

Abstract: Capacitance underpins a wide spectrum of impedance-based sensors, yet the usual method of using iterative finite-element modelling of frequency-dependent, fringing-field geometries is ...
