Executive Summary

Wireless sensing can be utilized to monitor multiple targets in various fields, including biomedical, civil engineering, automation, aerospace, and defense. Conventional radio waves do not travel well through conductive mediums, such as metal and sea water. This poses an issue for certain applications, like monitoring the corrosion of metal structures. Instead, acoustic waves are used to probe and transmit information.  However, current methods of acquiring information from acoustic transducers are active, which limits their usability, field-operability, and life span. This technology enables a low-cost, passive wireless tag for improvement in acoustic detection systems.

Description of Technology

This technology is a wireless multiband sensing unit compatible with monitoring and preventative maintenance applications in numerous industries. The sensing unit offers significant advantages, such as real-time and non-invasive monitoring, lower clutter-rejection and a long interrogation range. The sensing unit operates on any FCC-approved antenna or frequency band for transmission or reception of information. This technology allows for a seamless transition between frequency bands so acoustic waves can be actuated in any medium and detected independently and wirelessly.

Key Benefits

• Passive: Improved Life-Span
