In this paper, we present the electromagnetic characterization of the chitosan-based hydrogel in ultra-wideband (UWB) frequencies, and its use as a pH sensor with chipless radio frequency ...

Elecrow hit Kickstarter with an electronics learning lab-in-a-box based around the Raspberry Pi. A 2nd generation crammed the lab into a laptop form factor. The CrowPi 3 "playground for programming, ...

Abstract: We present a low-power gas sensor design based on a capacitive micromachined ultrasonic transducer (CMUT), for use on self-powered wearable platforms. Earlier a CMUT-based sensor, with 70-mW ...

We propose a micro-ultrasonic diagnosis using an all-optical ultrasound-based spectral sensing (AOUSS) technique for sensitive and quantitative characterization of early stage and whole blood ...

A real-time object detection and distance measurement system using the HC-SR04 ultrasonic sensor, developed in Embedded C for the LPC1768 microcontroller using Keil μVision.
