Helium is inert, which makes it useful in a lot of different industries. But helium’s colorless and odorless non-reactivity ...

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

What if you could send sound directly to a single person in a crowded room, without anyone else hearing it? This isn’t a scene from a sci-fi movie, it’s the reality of a new concept called the “sound ...

Finnish scientists sent electricity wirelessly using sound waves and lasers. "Acoustic wire" uses ultrasonic waves for contactless electricity transmission. Finland pioneers practical wireless ...

The parking sensor sound on the Dacia Duster is generally designed to assist drivers while parking by providing audible warnings as the vehicle approaches obstacles. Weight-loss drugs draw thousands ...

Rechargeable lithium-ion batteries are the bedrock of today’s tech-driven society. They underpin everything from smartphones and electric vehicles, to even our homes. To take us into a greener future, ...

Cylinders and tubes: The structure of the helium detection device was inspired by the Japanese bamboo-weaving technique known as Kagome-biki. This triangular structure (shown in detail at left) helps ...

Main Camera Quad 200 MP, f/1.7, 24mm (wide), 1/1.3", 0.6µm, multi-directional PDAF, OIS 10 MP, f/2.4, 67mm (telephoto), 1/3.52", 1.12µm, PDAF, OIS, 3x optical zoom ...

This project implements a real-time closed-loop motor control system where motor speed is dynamically regulated based on obstacle distance. An ultrasonic sensor provides the reference input, an ...

Abstract: In this paper, we propose the use of ultrasonic sensors for autonomous parking systems. In general, LiDAR sensors are evaluated to be advantageous in autonomous parking systems, but this ...
