Abstract
A temperature probe includes: an antenna, a coupling element, a radio frequency identification (RFID) chip and a temperature measuring circuit. The antenna is connected to a capacitor in the coupling element to form a resonant loop, and is configured to sense an electromagnetic wave emitted by a reader and a store harvested energy in the capacitor to supply power to the RFID chip. The RFID chip is connected to the antenna and the coupling element, and is configured to send stored electronic tag information to the reader via the antenna. The temperature measuring circuit is connected to the RFID chip, and is configured to detect temperature information of an object and to send the temperature information to the reader via the antenna. Also provided is a temperature measuring device. The temperature probe and the temperature measuring device do not require a battery, are small-sized, and have a long service life.
