Modern piezo transducers can emit and detect high-frequency sound (often in the range of 5 to 10 MHZ), when used in conjunction with special electronic amplifiers.

Imec has developed an optomechanical ultrasound sensor on a silicon photonic chip that has an unprecedented sensitivity due to an innovative optomechanical waveguide. Because of this high-sensitivity ...

While most common piezo transducers are based on PZT formulations, lead-free PIC700 material is currently available, ideal for ultrasonic transducers in the MHz range and for hydrophone and sonar ...

Here, ultrasonic direct drives based on piezo actuators can pave the way for new opportunities. These devices are compact, quiet, self-locking and low-wear, and continue to maintain their position ...

The challenge here is in designing piezoelectric transducers that can produce very-high-quality sound within a small package, and without draining too much of the device’s battery. Medical ...

Piezo-based ultrasonic direct drives can pave the way for new opportunities here. They are quiet, very compact, low wear, and self-locking, maintaining their position when powered off and even if they ...

In the lab University of Connecticut researchers (from left to right): Kazem Kazerounian, Thanh Nguyen, Feng Lin, Thinh Le, Meysam Chorsi and Horea Ilies. The biodegradable ultrasonic transducer is ...

Many monitoring, sensing and characterization tasks in industry today are based on classic ultrasonic sensors. Micromachined ultrasonic transducers (MUTs) represent an innovative and effective ...
