“Bio-Thermo” implantable tags combining animal ID and temperature measurement are manufactured by Destron Fearing (www.destronfearing.com). The Bio-Thermo tags were originally produced by a company named “Digital Angel” in Delray Beach, FL. The Bio-Thermo tag is covered under a 2006 US Patent No. 7,015,826 “Method and Apparatus for Sensing and Transmitting a Body Characteristic of a Host.”
Digital Angel merged with Veriteq in 2013. VeriTeq owned the IP to Sicel’s implantable dosimeter products. VeriTeq is no longer in the business of selling human or animal ID tags, probably as a result of the outcry by the ignorant populace claiming that implantable RFID chips are “the Mark of the Beast”. Instead, they have reinvented their tags approved for human use as UDI (unique device identifiers) for medical devices. Their website states that they plan to relaunch the implantable radiation dosimeters.
The Bio-Thermo tag is a small (12mm length) “microchip” which offers a unique numerical identity, as well as instantaneous temperature recording accurate to 0.1 degree F or C using its Bio-Thermo™ sensor. Although Bio-Thermo™ is implanted subcutaneously in the shoulder region, the correlation of the temperature with the traditional rectal reading is excellent. Multiple temperature readings can be taken with no stress to the patient, so it is ideal for monitoring temperature after surgery where minimal disturbance is desired. Non-invasive measurements also allow easy monitoring of animal health, wellness, and breeding cycle.
