At the present time there is no system to monitor the progress of medical shipments to and within the combat theater other than those pallets that are tagged with Radio Frequency Identification (RFID) tags in compliance with the current DoD mandate for tagging pallets and cases. Full implementation of the DoD mandate to tag all pallets and cases of Class VIII (Medical) materiel is not expected to occur before the end of 2008. The DoD mandate not withstanding, most Class VIII shipments are of less than pallet or case quantity and therefore are not subject to this requirement. Many of these medical shipments are time sensitive and are often subject to damage from rough handling and/or environmental exposure. Very often the timely delivery of these items, in good condition, is necessary to save human life or limb or to alleviate human suffering. Thus, an RFID system with the ability to monitor the condition of the medical shipments in transit is of vital importance. In the Small Business Innovation Research (SBIR) Phase I Contract W81XWH-08-C-0014, Eigent conducted a technology feasibility study and considered alternative strategies for an AIT enabled system to provide tracking/in-transit visibility (ITV) of less than pallet/case quantity medical shipments from the point of origin, or from an intermediate shipping point such as a military medical depot, to the point of use. This research demonstrated that RFID sensor tags have the potential to: 1. monitor the condition of sensitive medical shipments in transit; 2. report temperature, humidity, vibration and/or shock; 3. be compact in size; 4. be low cost and disposable; 5. require no battery replacement over their useful life; 6. provide early notification of possible damage to essential medical materiel; 7. require minimal human intervention; and 8. be capable of being integrated into the Defense Medical Logistics system(s).
