Simple circuit ratios sensor capacitance to reference capacitor to measure micrometers. It’s hard to imagine a simpler electromechanical sensor than the capacitance type, consisting of little more ...

We often like to say that if something is worth doing, then it’s worth overdoing. This automatic cat feeder built by [krizzli] is a perfect example of the principle. It packs in far more sensors and ...

Encoders are a vital component in many applications that require motion control and feedback information. Whether a system’s requirement is speed, direction, or distance, an encoder produces control ...

The ability to control the movement of negatively charged particles (i.e., electrons) is central to the functioning of all ...

The scientific community cannot always agree on how much water a person needs in a day, and since we are not Fremen, we should give it more thought than we do. For many people, remembering to take a ...

Regulated helical orientation of polymer chains proved to greatly enhance fiber mechanics, and the highly stretchable fibers were capable of simultaneously sensing and decoupling tensile and torsional ...

The Mpox outbreak in Sierra Leone necessitated fast, decentralized testing. Here, authors developed and validated Mpox SHINE, a portable CRISPR diagnostic that delivered 100% accurate results on ...
