An automatic toll gate system using Arduino revolutionises traditional toll collection by eliminating manual intervention.

Abstract: Metamaterial temperature sensors are gaining increasing attention due to their wireless passive operation. Most metamaterial temperature sensors are single-layer resonance structures, which ...

Abstract: This study presents a miniature triaxial fiber Bragg grating (FBG) vibration sensor incorporating a novel elliptical guide-angle hybrid flexure hinge structure for stepper motor vibration ...

Stealth jets aren’t truly invisible. Discover how modern radars, low-frequency sensors, and real-world conditions can still detect advanced fighters like the F-35 and J-20. Stealth jets like the F-35 ...

Stealth jets like the F-35 and China’s J-20 are designed to disappear — so why do they still show up on radar? In this video, we break down how radar cross-section, low-frequency sensors, multistatic ...
