The Korea Research Institute of Standards and Science (KRISS) has developed an ultrasonic sensor technology that applies a waveguide to detect defects in all directions without directly attaching ...

Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...

Without any delays, here are the best Phones with Ultrasonic Fingerprint Sensors (March 2026) that make the cut: ...

Dr. Park Chan Wook (Postdoctoral Researcher, Non-Destructive Metrology Group, KRISS); The Korea Research Institute of Standards and Science (KRISS, President Lee Ho-seong) has developed an ultrasonic ...

Abstract: Stable operation of transformers is vital for the security of power grids. And the partial discharges can lead to insulation degradation and potential transformer failures. This paper ...

Abstract: Robotic Continuous Ultrasonic Welding (cUSW) provides significant advantages, including efficiency, flexibility, and the capability to weld complex geometries with high repeatability. These ...

Exceptional points (EPs) in non-Hermitian systems offer a strong response to perturbations, offering a promising platform for sensing. By using a third-order EP of coherent perfect absorption, here, ...

A car that hesitates when the accelerator is pressed is usually experiencing a fuel delivery problem, an ignition issue, or a ...
