Abstract: This article presents a compact phase- variation sensor that achieves high linearity and a large phase variation at a single frequency for wide-range permittivity measurements. The sensing ...

Wearable health sensors such as photoplethysmography (PPG) wristbands, ECG patches and multi-modal biometric devices are typically developed and calibrated under controlled laboratory conditions.

Wrist pulse oximeters can look similar, making it hard to decide which one to buy. This in-depth guide covers everything you need to know to find your best fit.

Inside every cell are lipid molecules that make up cellular membranes, helping organelles communicate and respond to stress.

A biomechanical well plate inspired by the pressure-sensing lateral line of fish can wirelessly monitor the pulse of multiple ...

Among study participants, fecal testing increased by 36.57% and colonoscopy screening increased by 55.56% from 2014 to 2022. Adults participating in an organized, population-wide colorectal cancer ...

Many electric vehicle (EV) power electronics systems use silicon carbide (SiC) and gallium nitride (GaN) devices. These wide-bandgap (WBG) semiconductors enable significantly higher switching ...
