Current Photoacoustic tomography (PAT) approaches are based on a single-element transducer that exhibits compromised performance in clinical imaging applications. For example, vascular, tumors are ...

In the present study, the modal properties of an ultrasonic stack are investigated. The ultrasonic stack comprises a wide horn. The horn of the ultrasonic stack is designed with the genetic algorithm.

Butterfly Network. has been granted a patent for an ultrasonic transducer device featuring a patterned film stack with a metal electrode and bottom cavity layer, a planarized insulation layer, and a ...

The transducer, booster and horn make up the ultrasonic stack. Power is sent to the transducer, which contains piezoelectric crystals that expand and contract. This action causes mechanical vibrations ...

In the plastics processing industry, ultrasonic welding is highly respected. This technology enables high process speeds with consistent and reproducible weld quality along with low energy ...
