'Tania K. Morimoto' 'Dinesh Bharadia'] Any two objects in contact with each other exert a force that could be simply due to gravity or mechanical contact, such as a robotic arm gripping an object or even the contact between two bones at our knee joints. The ability to naturally measure and monitor these contact forces…

An outstanding event related to the understanding of the physics of mechanical sensors occurred and was announced in 1954, exactly seventy years ago. This event was the discovery of the piezoresistive effect, which led to the development of semiconductor strain gauges with a sensitivity much higher than that obtained…

'Aldo Minardo' 'Nunzio Cennamo' 'Cosimo Trono'] The transition toward more electric aircraft (MEA) and all-electric aircraft (AEA) has driven the adoption of high-voltage DC (HVDC) electrical architectures to meet increasing power demands while reducing weight and enhancing overall efficiency. However, HVDC systems…

The effectiveness of passive human body capacitance (HBC) sensing relies heavily on the careful design of the sensing hardware. Because the electrostatic signals involved are extremely weak and sensitive to environmental influences, hardware implementations must strike a balance between signal fidelity, power…

— Force and proximity sensors are key in robotics, especially when applied in collaborative robots that interact physically or cognitively with humans in real unstructured environments. However, most existing sensors for use in robotics are limited by: 1) their scope, measuring single parameters/events and often…

The pervasive model for a solvated, ion-filled nanopore is often a resistor in parallel with a capacitor. However, for conical nanopore geometries, we propose the inclusion of a Warburg-like element which is necessary to explain otherwise anomalous observations such as negative capacitance and lowpass filtering of…
