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, ...

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.

Cancer is one of the leading causes of death in the U.S., second only to heart disease. But a new cancer treatment method from CU Boulder researchers uses sound waves to soften tumors and could be a ...

Scientists have boosted the motility of sluggish sperm by up to 266%, by blasting the cells with noninvasive, 40-MHz ultrasound waves to induce movement. Capturing the technique's impact on individual ...
