Description

technical field [0001] The present application relates to the field of implantable devices, in particular to an implantable RFID tag device for obtaining body temperature of animals. Background technique [0002] Animal health is judged by measuring body temperature. There are mercury thermometers and electronic thermometers on the market. In the related technology, through wearable electronic ear tags, Bluetooth technology, temperature sensor and button battery are used to measure the temperature by skin contact. It relies on the contact between the temperature sensor and the ear skin to obtain the skin temperature, which does not represent the real temperature due to the influence of the environment. In addition, the drop-off rate of wearable electronic ear tags is as high as 60%. [0003] The inventors of the present application have discovered that the implantable device can detect body temperature and is not easy to fall off. However, electronic thermometers in the r...
