The Korea Research Institute of Standards and Science (KRISS) has developed an ultrasonic sensor technology that applies a ...

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 ...

Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based u-blox NINA-W102 wireless module, ...

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

I'm returning to an old project today to fix it since it got broken during my recent move. This toy I made for my dog is very fun project where an Arduino controls two servos so they can move a laser ...

CU Boulder researchers have built high-performing optical microresonators, opening the door for new sensor technologies. At its simplest form, a microresonator is a tiny device that can trap light and ...

Nature does it again! The natural world has a knack for giving us the blueprints for some useful technologies, and the humble sea urchin is the latest contributor. Scientists have designed a new class ...
