A research team has developed the world's first high-performance photoacoustic endoscopy based on a transparent ultrasonic transducer. Their findings were recently published in the journal Science ...

Piezoelectric micromachined ultrasonic transducers (PMUTs) harness the direct and inverse piezoelectric effects in thin-film materials deposited on micromachined silicon substrates to generate and ...

A team develops an ultrasensitive broadband transparent ultrasound transducer. The 'ultrasound-photoacoustic dual-modal imaging system' combines molecular imaging contrast with ultrasound imaging, and ...

Scientists develop a high-performance photoacoustic endoscopy featuring a transparent ultrasound transducer. Recently, a research team consisting of Professor Chulhong Kim from the Department of ...

Ultrasonic levitation is by now a familiar trick: one or more ultrasonic transducers create a standing wave, and small objects can be held in the nodes of this standing wave. With a sufficiently large ...

The notion of a phased array was initially articulated by Nobel Prize recipient K. F. Braun. Phased arrays have subsequently evolved into a formidable mechanism for wave manipulation. This assertion ...
