A new technology has been developed that enables cuffless noninvasive blood pressure monitoring by using ultrasonic to track ...

A newly published patent proposes a single-sided ultrasonic levitation printer that maintains contactless deposition even ...

There is a lot of buzz about electromagnetic (EM) detection and ranging sensor technology, which encompass radar, lidar, infrared (IR), ultra-wide bandwidth (UWB), and many others. However, there are ...

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 ...

혈압 측정 밴드 없이 초음파로 혈압을 연속 측정하는 기술이 개발됐다. 피부에 붙이는 초소형 센서로 혈관 직경 변화를 실시간 감지해 혈압을 계산하는 방식이다. 웨어러블 헬스케어 기기의 핵심 기술로 활용될 전망이다.

This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...
