Strontium Titanate Composites for Microwave-Based Stress Sensing
Source abstract
Abstract
Composites of strontium titanate ceramic particles dispersed in epoxy resin have been manufactured for nondestructive wireless stress sensing. Magnetic coupling with a hairpin resonator on the surface of the composite was used to detect changes in the effective dielectric properties. The hairpin resonator was excited in the microwave frequency domain at 1–10 GHz, and its resonant frequency detected using a network analyzer based on the absorbed power. The results indicated a shift in the resonant frequency of the hairpin resonator under application of stress due to a change in the dielectric constant of the composite.
