High sensitivity industrial production batches, such as pharmaceutical freeze drying, need accurate monitoring abilities so that producers can ensure the batches are at the optimum production value. To monitor the temperature of a batch, thermocouples are placed in the packaging or attached to a single product. Current technology requires either a web of wires threaded through the packaging to power the thermocouples or bulky batteries within the packaging. This method is invasive and obtrusive to the product and needs to be updated.

Researchers from Purdue University have developed battery free, vial printed temperature sensors/thermocouples, which can be printed on an adhesive substrate and placed on a vial and other surfaces. The temperature sensors can be integrated into a 2.4 GHz, low-power, wireless system, which is powered using a wireless energy harvester, ensuring battery free operation and real time data. This solution provides an almost noninvasive solution to process monitoring.

Advantages:
-Comprehensive data collection
-Noninvasive

Potential Applications:
-Printed circuits
-Pharmaceutical freeze drying
-Industrial batch monitoring
