Abstract: A hydrogen gas sensor based on peak-delay measurement of ultrasonic time-of-flight (TOF) is reported. The sensor integrates a time-to-digital converter (TDC), a pair of 200 kHz ultrasonic ...

SEATTLE — The Pacific Northwest Seismic Network (PNSN) announced their upcoming collaboration with the Seattle Seahawks and Lumen Field to measure ground motion during the 2026 NFL Playoff Games. On ...

Quantum sensors are transforming how we measure and navigate, offering levels of precision far beyond classical systems. By exploiting atomic superposition, cold atom interferometers, and diamond NV ...

A new technology has been developed that enables cuffless non-invasive blood pressure monitoring by using ultrasonic to track real-time changes in vascular diameter—without the need for a traditional ...

Abstract: Here a microwave sensor for non-invasive blood glucose measurement is proposed. To achieve a high sensitivity, this sensor uses a complementary electric-LC resonator with strong ...

For electrical engineers working in almost any part of the wired or wireless spectrum, the spectrum analyzer is a critical test and measurement tool. For optical engineering, the equivalent tool is ...

Ultrasonic sensors measure the distance between a target and the sensor using high-frequency sound waves that are inaudible to humans. The process is simple: the sensor emits ultrasonic waves, which ...

Thermopile sensors offer a reliable way to measure temperature without physical contact, making them ideal for real-world applications where speed, safety, and precision matter. Whether you are ...

In a new study, physicists at the University of Colorado Boulder have used a cloud of atoms chilled down to incredibly cold temperatures to simultaneously measure acceleration in three dimensions—a ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...
