In this work, we propose FabToy, a plush toy instrumented with a 24-sensor array of fabric-based pressure sensors located beneath the surface of the toy to have dense spatial sensing coverage while ...

Or, you can buy an ultrasonic cleaning machine and let it do all the work instead. These countertop contraptions—which we have not tested—claim to dislodge food bits, bacteria, and the like ...

Ultrasonic sounds are high-frequency sound waves that exceed 20,000 hertz, making them too high-pitched for human ears to detect. These sound waves vibrate more than 20,000 times per second. Doctors ...
