Time-Temperature Integrator Advanced E-Team

University of Florida, 2005 - $15,700

This E-Team is concentrating on the problem of the perishability of food and pharmaceutical items. Currently there are two methods of ensuring food/pharmaceutical safety: human predication of expiration, and chemical tags that change color upon product expiration. The E-Team aims to combat the deficiencies of these methods by developing a Time-Temperature Integrator (TTI) tag which, in a 1x2 inch housing, incorporates a temperature measure, a microprocessor, and an RF transceiver. Instead of using the color-change method, these tags record the temperature and time at thirty-second intervals. A calculation of shelf-life is then made based upon a proprietary algorithm that takes into account the current time/temperature and the optimal shelf-life of perishables under those specific conditions. A report of time, temperature and freshness is then sent to a wireless device.
