Although there are now many skin-worn sensors which identify metabolites in sweat, the tech is limited in what it can detect, plus the sensors often aren't reusable. A new one, however, utilizes a ...

Saraf’s new sensor, unlike prior versions, will be able to detect the shape of the protein and the DNA sequence without any chemical tag.

The flexible, electronic sensor is a small square patch, measuring less than 1 inch (2 centimeters) in height and width; it's made of conductive polymer material with embedded spiral-shape capacitors.

TK has combined a PIR with an Arduino to create a smart safety light for the house or workshop. Follow along as this gets built out into a more extensive project.

He suspected EMF interference so as a quick first step he decided to throw together an EMF detector using an Arduino. It uses a bank of LEDs as an indicator bar to reflect the EMF picked up by the ...

The sensor operates on standard 5V power and can detect as little as 2.8mm of standing water in the bottom of the battery pack enclosure.

A new sticker changes in shape inside the body, enabling standard ultrasound technology to detect leaks for earlier detection and intervention. John Rogers, Louis Simpson and Kimberly Querrey ...

To beat cancer, early detection is crucial. Now, a team of Japanese and American scientists has revealed extremely thin sensors that could one day be built into skin-tight, tumor-detecting gloves ...

You can make a perfectly good water detector with things you probably already have around the house. My point isn’t that you should (or shouldn’t) construct a homemade water sensor.

Researchers have developed a sensor made from 'frozen smoke' that uses artificial intelligence techniques to detect formaldehyde in real time at concentrations as low as eight parts per ...

Waymo's sensor suite allows its robotaxis to see pedestrians in ways cameras may not be able to detect, co-CEO Dmitri Dolgov said.
