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 ...

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 ...

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 ...

Abstract: The positioning and posture of hands on the steering wheel are crucial for ensuring road safety while driving. This letter introduces a novel π-model capacitive sensor designed for detecting ...
