The Korea Electronic Communications Research Institute has developed an electronic tag that can measure changes in temperature and humidity, which can be used for food freshness detection and environmental pollution monitoring. Electronic tag is a non-contact automatic identification technology. It automatically identifies target objects and obtains relevant data through radio frequency signals. Compared with the widely used bar code technology, electronic tags have the advantages of waterproof, antimagnetic, high temperature resistance, long service life, and long read distance. According to South Korea's "Daily Economic News" reported on the 2nd, the newly developed bar-shaped electronic tag built-in processor, high frequency antenna and storage components. When it is affixed to the human body, animals or objects, it automatically senses changes in temperature and humidity. The reader can not only read the information previously stored in the tag, but also can know the current temperature and humidity of the object on which the tag is located. Compared with previous electronic tags, the new tag's data recognition distance has also increased from 6 to 10 meters to 10 to 12 meters. The Korea Electronic Communications Research Institute also plans to add a function to identify quake and stress based on the electronic tags that were developed this time. The new electronic label will be put on the market in 2008, and the price after mass production is expected to be reduced from the current US$1.6 to US$0.01.

The size of the infrared radiation energy of an object and its wavelength distribution are closely related to its surface temperature. Therefore, the surface temperature of the object can be accurately measured by measuring the infrared energy radiated by the object itself. This is the principle on which the infrared thermometer operates.

After the outbreak, measuring body temperature has become a convenient and intuitive way to find potentially infected people. Many regions require companies to prepare non-contact temperature measuring instruments when they resume work.
