Unsurprisingly, inside you find not the ultrasonic transducer that you’d expect to find in an actual ultrasonic cleaner, but rather a vibration motor.

We’d love to find a source for those ultrasonic transducer devices, and can only guess at the physical arrangement that allows for air to pass in one direction only, to effect a net thrust.

Ultrasonic sensors have been a staple in the sensing space for several decades due to their capabilities, flexibility, and low cost. As the rise of IoT finds its way into virtually every market and ...

The HC-SR04 ultrasonic range sensor is a pretty cool pre-wired module that you actually enjoy using when you start playing with electronics, microcontrollers, and robotics. As you might have noticed, ...

HIFU concentrates ultrasonic energy into a focal region by using an ultrasonic transducer, which converts electrical signals into sound waves, to raise the temperature within the tumor to above 65 ...

However, a major limitation is that each focused ultrasound transducer has a fixed focal length. This means that multiple transducers with different focal lengths must be purchased, leading to ...

The wearable ultrasound sensor is roughly the size of a postage stamp, can be worn for up to 24 hours, and works even during strenuous exercise. Image Credit: Xu Laboratory, UC San Diego Jacobs ...
