Latest Patents

James T Stewart holds a patent for a device titled "Remote sensing of structural integrity using a surface acoustic wave." This invention involves a SAW sensing device designed to remotely assess the structural integrity of a physical structure. The device features a piezoelectric substrate with a notch, which is mounted to the structure of interest. An antenna is integrated with the RF circuit on the substrate, enabling the reception and transmission of RF signals. The device includes input and output transducers that facilitate the sensing process. When the substrate experiences strain beyond a critical level, it fractures along the notch, indicating a failure in the SAW sensor and a compromise in structural integrity.
