PPG is an optical technique that uses light to detect blood volume changes in the skin. As a result, PPG is widely used in ...

Abstract: We propose and experimentally demonstrate a new polarization-reciprocal angular velocity measurement scheme based on an optoelectronic oscillator (OEO) with a Sagnac loop. The scheme employs ...

TDK Corporation introduces the stray-field robust Micronas HAL/HAR 35xy 2D Hall-effect position sensor family for automotive and industrial applications. Building on the success of the HAL/HAR 39xy ...

CHICAGO — In this video, Clement K. Chan, MD, FACS, recaps a lecture from the Macula Society symposium at the AAO meeting. In the Arnall Patz Lecture, Richard F. Spaide, MD, discussed advancements in ...

High-accuracy ASC sensors ensure safe and comfortable train operation. Without inertial sensors, modern rail transport would be inconceivable. They detect the position of trains, monitor the state of ...

Carotid-femoral pulse wave velocity (cfPWV) is the gold standard for noninvasive arterial stiffness assessment, an independent predictor of cardiovascular disease, and a potential parameter to guide ...

In a recent article published in Scientific Reports, researchers introduced a novel method for measuring water velocity in open channels and rivers using optical fiber sensors based on fiber Bragg ...
