Just about every “getting started with microcontrollers” kit, Arduino or otherwise, includes an ultrasonic distance sensor ...
Abstract: An exceptionally sensitive and photothermally tunable polymer microbubble is fabricated at the fiber tip for enhanced ultrasonic detection. A modified acrylate adhesive (MAA) is applied to ...
Ultrasonic energy is widely used to sense the presence of nearby objects and even determine their distance if needed, as well as to measure fluid flow rates in industrial and scientific applications.
