Detection of Water and Ice on Bridge Structures by AC Impedance and Dielectric Relaxation Spectroscopy - Phase III - FY10 NATSRL
Principal Investigator:
John Evans, Professor, UMD-Chemistry and Biochemistry
Project Summary:
This project is the third phase of an existing NATSRL project and aims to improve the technology used to detect water and ice on bridges. These sensing systems are based on the impedance response of sensors in relation to ice, water, or other aqueous solutions, and can be produced at a low cost. In this phase, researchers are focusing on high-frequency dielectric relaxation by using time-domain reflectometry, which probes the physical state of the precipitation and the deicing chemicals on the deck or road surface.
