In this paper, a quasi-spherical PVDF airborne ultrasonic transducer for three-dimensional (3D) ultrasonic location systems is designed and fabricated using two strips of cylindrical PVDF film. The 3D ...

The main contributions are related to the utilization of a 0.8 MHz ultrasonic air-coupled concave array transducer. This transducer, using only 32 elements, is able to generate a 2.5 square cm size ...

Ultrasonic humidifiers: Instead of electricity, these units use vibrations to vaporize water. Evaporators: These produce humidity by blowing air past evaporating water.

The Korea Research Institute of Standards and Science has developed a detachable acoustic lens that allows for easy adjustment of the focal length in ultrasonic inspection equipment. Much like ...

The Doppler transducer will be pressed against the skin and moved around over the area of the artery being looked at. When blood flow is detected, you will hear a "whoosh, whoosh" sound. The probe ...
