Salinity and Sugar Content Detection by Wideband Microwave–Based Patch Antenna Sensor
Journal of Electrical and Computer Engineering, Volume 2025, Issue 1, 2025.This article studies a dielectric microwave sensor to identify salinity and sugar concentration. The lightweight patch‐antenna–based wideband sensor is designed to propagate the electromagnetic wave for the transmission and reception. With a broken‐heart‐shaped patch, the sensor is printed on common FR4 material.

Low‐cost animal tracking using Bluetooth low energy beacons on a crowd‐sourced network
Methods in Ecology and Evolution, Volume 15, Issue 12, Page 2247-2261, December 2024.Abstract Animal tracking has opened the door to address many fundamental questions in ecology and conservation. Whilst historically animals have been tracked as a means to understand their large‐scale movements, such as migration, there is now a greater focus on using tracking to study movements over smaller scales, individual variation in movement or ...

Dielectric‐Doped 2D Tellurium Diodes for Zero‐Bias Radio Frequency Power Detection
Advanced Electronic Materials, Volume 10, Issue 11, November 2024.This work presents a 2D Tellurium (Te)‐based radio frequency (RF) diode that exploits a dielectric doping technique to enhance its performance as a power detector. The atomic layer deposited Al2O3 is used to n‐type dope the Te flake to engineer the rectifying Schottky contact.
