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

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 ...

To derive blood pressure, the device measures the time-of-flight between ultrasound echoes reflected from the anterior and ...

Piezoelectric ultrasonic transducers play a critical role in modern sensing and actuation by converting electrical signals into high‐frequency mechanical vibrations and vice versa. Recent advances ...

KIRKLAND, Wash.--(BUSINESS WIRE)--Verasonics, Inc., the leader in research ultrasound, today announced it has enhanced the Vantage Research Ultrasound System with the introduction of the Verasonics ...

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.

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 ...

To measure wind speed and direction, most people turn the traditional cup anemometer and wind vane. Another less-known method is to use an array of ultrasonic transducers, which doesn’t need any ...

Ultrasonic nondestructive testing, also known as ultrasonic NDT or simply UT, is a method of characterizing the thickness or internal structure of a test piece using high-frequency sound waves. The ...
