Diagnostic radio frequency identification sensors and applications thereof
First Claim
1. An immunoassay test strip system for use in conducting quantitative immunoassay diagnostic measurements comprising:
- an immunoassay test strip including a substrate;
at least one test area located on said substrate for capturing antigens that flow through the immunoassay test strip;
a radio frequency identification (RFID) tag and a sensor module combination electronically connected to each other and integrated with said substrate;
said sensor module capable of quantitatively detecting captured antigens on said test area and said RFID tag and sensor module combination being capable of generating and transmitting at least one signal that includes information regarding the quantity of said antigen captured on said test area and identification of the RFID tag and sensor module combination;
a wireless reader adapted to communicate wirelessly with said RFID tag and sensor module combination through the use of multiple protocols to receive said at least one signal that corresponds to the quantity of antigens captured by said at least one test area; and
said wireless reader further adapted to communicate wirelessly over a network through the use of multiple communication protocols to download software wirelessly from a remote location based on the identification of the RFID tag and sensor module combination to enable reading and analysis by said wireless reader of the at least one signal received from said RFID tag and sensor module combination.

Abstract
An integrated passive wireless chip diagnostic sensor system is described that can be interrogated remotely with a wireless device such as a modified cell phone incorporating multi-protocol RFID reader capabilities (such as the emerging Gen-2 standard) or Bluetooth, providing universal easy to use, low cost and immediate quantitative analyses, geolocation and sensor networking capabilities to users of the technology. The present invention can be integrated into various diagnostic platforms and is applicable for use with low power sensors such as thin films, MEMS, electrochemical, thermal, resistive, nano or microfluidic sensor technologies. Applications of the present invention include on-the-spot medical and self-diagnostics on smart skin patches, Point-of-Care (POC) analyses, food diagnostics, pathogen detection, disease-specific wireless biomarker detection, remote structural stresses detection and sensor networks for industrial or Homeland Security using low cost wireless devices such as modified cell phones.
