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 ...

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.

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.

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 ...

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 ...

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.
