[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The ...

A new simple tool developed by nanoengineers at the University of California, San Diego, is opening the door to an era when anyone will be able to build sensors, anywhere, including physicians in the ...

Here is the circuit diagram of a simple steam sensor, wired around a handful of inexpensive components. This steam sensor can be connected to a microcontroller’s I/O port directly. The steam sensor ...

Nanoengineers from the University of California, San Diego are making it possible for anyone to build sensors at any time with high-tech bio-inks that react with several chemicals, including glucose.
