MEI has developed 2-D and 3-D passive antenna fabrication technology using non-standard, additive manufacturing processes. These RF structures can be coupled with embedded chemical sensors (measuring, for example, gas concentration, pH and conductivity) or physical sensors (measuring, for example, pressure, temperature and strain) to form comprehensive passive wireless sensor networks. These highly miniaturized wireless sensors can be used for many applications including non-destructive testing, in-situ health monitoring and remote environmental monitoring. Large networks of RF coupled sensors can be deployed and combined with MEI’s machine learning applications for real-time monitoring of structures, aerospace vehicles, remediation sites and energy production wells.
