Researchers from the Physics Laboratory of England have created a sensor to measure ultrasonic cleaning of surgical devices. The invention has quantitatively measured this ultrasonic bubble cleaning.

For the disinfection of surgical instruments by ultrasonic cleaning, the instruments are first inserted into a disinfectant liquid. High frequency sound waves are then sent through the liquid, resulting in small bubbles that break. The sensors are designed for placement in the liquid and for recording the high-frequency sound of bubble implosion. So far, the most widely used method was to wet an aluminum foil in liquid and see the marks of the bubbles explosions. But this method only performed a qualitative measurement.
