A Smart Sensor for Robots to Feel Metals like We Do

Imagine if robots could feel and sense the world around them like humans do. That's what scientists have been working on with a new flexible sensor. This sensor is like a tiny, smart patch that can detect pressure, temperature, and even magnetic fields. It's made of a flexible coil on a polyimide base and mixed with materials called MXene and CNT aerogel. This combin...
