Temperature and humidity displacement measurement electronic tag

Abstract

The invention relates to a temperature and humidity displacement measurement electronic tag, the electronic tag comprises an electronic tag structure and a telescopic part, and the readability of the electronic tag structure is changed through the telescopic displacement of the telescopic part, so that the measured physical quantity is sensed. The electronic tag has the advantages of being passive, soft, thin, small, capable of achieving real-time measurement, low in cost and the like, various physical quantities are sensed through displacement of the telescopic part, and the electronic tag cannot be read when the structure is damaged or the electronic tag is close to a human body, liquid, metal and an electromagnetic shielding material; according to the characteristic, the electronic tag is switched from a readable state to an unreadable state through displacement change generated by contact between the telescopic pieces made of different materials and the measured object so as to sense different physical quantities, such as expansion, cracks, temperature and humidity, and the field which cannot be measured by traditional measurement can be completed.

Description

technical field [0001] The invention relates to the field of electronic tags, in particular to an electronic tag for temperature and humidity displacement measurement. Background technique [0002] Electronic tags are also called radio frequency tags, transponders, and data carriers; readers are also called readout devices, scanners, reading heads, communicators, and readers (depending on whether the electronic tags can rewrite data wirelessly). The spatial (non-contact) coupling of radio frequency signals is realized through the coupling element between the electronic tag and the reader; in the coupling channel, energy transmission and data exchange are realized according to the timing relationship. [0003] At present, in the existing technology, the measurement of physical quantities such as temperature and humidity is mostly carried out by corresponding sensors, which either require an active source, or are too large in size, or have high cost, or cannot be measured in r...

Problems solved by technology

[0003] At present, in the existing technology, the measurement of physical quantities such as temperature and humidity is mostly carried out by corresponding sensors, which either require an active source, or are too large in size, or have high cost, or cannot be measured in real time, and in terms of structural stability, product economy, etc. There is a lot of room for improvement in terms of , practicality, etc., and some more responsible environments cannot be used, which needs to be improved urgently
