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 ...

Ultrasonic sensors measure the distance between a target and the sensor using high-frequency sound waves that are inaudible to humans. The process is simple: the sensor emits ultrasonic waves, which ...

Implantable medical devices such as pacemakers and defibrillators use electrical pulses to regulate the heart. Despite technological advances in leads or electrodes, these devices still use batteries, ...

NTT Corp. (NTT) and Okayama University have developed a solution to the increasing problem of IoT signal interference by creating a topological ultrasonic circuit. Claimed as the first of its kind, ...

Alternatively, data from all transducers can be used while limiting the focal depth, allowing more transmit-receive pulses to ...

Both ultrasound for medical imaging and seismology for imaging the Earth's interior measure the propagation of waves through matter. For example, when seismic waves encounter material differences in ...

In a recent development, NTT Corporation unveiled the “first” gigahertz ultrasonic circuit that utilizes topological insulator principles, indicating a new era in ultrasonic communication technology.

Ultrasonic sounds are high-frequency sound waves that exceed 20,000 hertz, a range far beyond what the human ear can detect. These waves vibrate more than 20,000 times per second, creating a hidden ...

Encapsulated microbubbles (EMBs), tiny gas-filled bubbles coated in lipid or protein shells, play a central role in ...
