Time-Transient Wireless RF Sensor with Differentiative Detecting Capability for Target Ionic Solution of Water and Dielectric Objects Introduced into Water

Understand

A novel wireless microstrip-based RF sensor designed for detecting changes in ionic content of water and the addition of solid contaminant objects is proposed and demonstrated.

• The sensor can be installed on the exterior wall of dielectric containers and customized according to the material of the container to enable wireless sensing.
• Its operation within the lower microwave frequency range (670-730 MHz) serves to minimize signal attenuation in water and streamlines circuitry design.
• The most significant feature of this sensor is its unique design, rendering it impervious to its surrounding environment.
