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

Ultrasonics or ultrasound is a radar-like system that uses ultrasonic signals at frequencies above those typical for human hearing, usually above 16 to 20 kHz. The 40- to 70-kHz range tends to be most ...

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.

In industrial markets, semiconductor chipsets play a huge role in the transformation of mechanical equipment to electromechanical or purely-electronic equipment. Every market segment is broken down ...

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 ...

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 ...

Ultrasonic sensor transducers work well in medical applications such as patient monitoring, flow measurement and air bubble detection used in infusion systems, pharmaceutic devices or spirometry.

One of the biggest mistakes Tesla made last year was removing ultrasonic sensors from the cars without offering an alternative. With the 2022.45.11 software update, cars without ultrasonic sensors ...

A research team led by Dr. Shin Hur at the Korea Institute of Machinery and Materials (KIMM, President Seog-Hyeon Ryu), ...
