Abstract

The invention discloses a passive electronic tag having a temperature sensing function. The electronic tag has functions of an ultrahigh frequency smart tag and a temperature sensor at the same time, and comprises a chip, an antenna and a temperature sensing component, the chip is fixed on the surface of the antenna through glue, and a bonding pad on the chip is electrically connected with a bonding pad of the antenna through solidification of glue. The technology provided by the invention solves the problem that a temperature sensor must rely on a power supply for power supply and cannot realize convenient wireless transmission.

Description

technical field [0001] The invention relates to smart label technology and temperature sensor technology in the field of RFID technology, in particular to a passive electronic label with temperature sensing function. Background technique [0002] With the development of Internet of Things technology, the RFID industry as its foundation will also usher in a new round of opportunities and challenges. As far as the current industry situation is concerned, the related market of RFID will be further expanded, and more and more traditional industries will generate demand for RFID products. [0003] As the nerve terminal of smart cities, sensor technology will further expand its demand. At present, as a temperature sensor application, almost all of them are implemented by traditional active sensors. Traditional active sensors have a short service life, large product volume, complicated installation and use, and insufficient intelligence in data collection. , it is difficult to re...
