A school trip to Delhi's Sundar Nursery in 2023 left 17-year-old Mahi Malhani thinking about something beyond the park's ...

Measuring electric currents is an essential element of many electrical systems, but doing so in a way that is as nonintrusive as possible is not an easy problem to solve. Due to this we got a wide ...

During its recent Mobility Experience Days at the company’s Flat Rock, MI proving grounds, Bosch Mobility showed an example of how technology can be repurposed to provide previously unforeseen ...

You brush your teeth, floss regularly and faithfully wear your retainer every night. But despite your diligent oral health habits, your retainer or mouth guard can get yellowed, cloudy or stained. “A ...

This project demonstrates the control of an SG90 servo motor using an HC-SR04 ultrasonic sensor and an Arduino Uno. The ultrasonic sensor measures the distance between the sensor and an object. Based ...

Why passive ultrasonic offers a unique option of sensing discrete open/close events. How a team used passive, non-electronic metal tag for signal initialization. How they used DSP-based, non-ML, ...

The **HC-SR04 Ultrasonic Distance Sensor** is one of the most popular distance measurement modules used in Arduino, ESP32, robotics, and IoT projects. It measures the distance between the sensor and ...

If you’re unfamiliar, board-certified dermatologist Michele Green, MD, describes them as handheld devices that use high-frequency vibrations, typically between 20,000 and 30,000 hertz, to exfoliate ...

The sensor uses diamond NV technology to operate at room temperature, eliminating the need for cryogenic cooling systems. The device aims to provide full-vector magnetic field measurements with ...

Sonair’s ADAR One 3D ultrasonic sensor provides spatial awareness for robotic systems, enabling detection of people and obstacles across multiple heights in shared work environments. Sonair has ...

A biodegradable pressure sensor could help people with knee injuries exercise and heal faster, University of Connecticut researchers report in the 26 June issue of Science Advances. The knee can take ...

Researchers have demonstrated they can make coffee comparable to conventional espresso using ultrasonic waves. Because the process doesn’t need hot water, it consumes 75 percent less energy. The ...
