A novel chipless RFID humidity sensor based on a finite artificial impedance surface (AIS) is presented. The unit cell of the AIS is composed of three concentric loops thus obtaining three deep and ...

The effects of the concentrations of glutaraldehyde and FeCl 3 ·6H 2 O on the film’s structure and properties have been studied in detail; the results show that the strain sensor prepared from the ...

An ultra-sensitive optical fiber humidity sensor based on an extrinsic Fabry-Perot interferometer is proposed and experimentally demonstrated in this paper. The Fabry-Perot cavity is constructed by a ...

Embedr is an AI-powered Arduino-like IDE designed to simplify development for Arduino-compatible microcontrollers. It looks ...

An example of an outdoor theater setup, with a 100-inch Elite Screens Yard Master 2 screen and the Nebula Mars 3 projector mounted on the Vanguard Alto Pro2+ tripod. Adrienne Maxwell/NYT ...

As I've experimented and played with a lot of different sensors, I've discovered that these basic devices can be built for ...
