Ultrasonic transducers send and receive waves for many types of sensing. They convert energy into high frequency sound waves in the ultrasonic range. These sound waves are then focused on a target and ...

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 ...

Ultrasound can be used for industrial inspection and automation - the technology is similar to the one know from medical ultrasonic imaging. Piezoelectric ultrasonic transducers also find applications ...

The 'ultrasound-photoacoustic dual-modal imaging system' combines molecular imaging contrast with ultrasound imaging, and it can visualize molecular and structural information inside the body in real ...

Throughout the surgical process, the surgeon must have access to a real-time assessment of blood vessels to make evaluations relative to the flow of blood. Piezo transducers are at the heart of ...

Technical systems must be regularly checked for defects, such as cracks. Up to now, piezo sensors measuring pressure, force or voltage have been used to reliably detect such faults – but only to ...

Before humans discovered ultrasound for a variety of medical, technical and military applications, nature had perfected it over millions of years for navigation under and above water. Dolphins and ...

Philips said a Lumify diagnostic ultrasound software issue may prevent scans in the field if Wi-Fi and cell service are ...

I needed a simple mist maker/humidifier for a project that I was working on. I found lots of ideas on the internet, but they all lacked in one area or another, so I decided to design one. The ...
