Ultrasonic wave is a powerful tool for many applications, such as structural health monitoring, medical diagnosis and partial discharges (PDs) detection. The fiber optic extrinsic Fabry–Perot ...

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 ...

Hydrogen (H 2) is considered to be a clean and renewable energy source that is promising in various fields as energy battery, chemical production, medical, aerospace and etc. Due to flammability and ...

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 ...
