If you build engines, tune cars, or even just like mashing your foot on the throttle with conviction, you’ve probably heard the term “wideband O2 sensor” being thrown around at the track, dyno ...

Abstract: In this paper, we demonstrate a CMOS image sensor with high extinction ratio on-chip polarizers with 65-nm standard CMOS technology. The polarizer is based on a metal wire grid fabricated ...

Abstract: A novel robust approach for permittivity measurements of liquid materials in a wide frequency range is proposed. A high-sensitivity microwave-fluidic sensor is developed enabling direct ...

For more than a century, scientists have wondered why physical structures like blood vessels, neurons, tree branches, and other biological networks look the way they do. The prevailing theory held ...

Blood vessels, neurons, and tree branches often form junctions that look irregular, yet they follow a shared geometric rule. Using three-dimensional scans from six kinds of organisms, researchers in ...

An intelligent refrigerator management system built for Raspberry Pi 5, featuring computer vision, IoT sensors, cloud connectivity, and AI-powered intelligence.

(p) Examples of solvent uptake plots for (k–n) during SVA, with the corresponding ϕ s value shown in the inset that the film was held at for 200 s. (q) is an orientation diagram of the swollen film ...
