Problems solved by technology

At present, many medicines, vaccines and blood products need to be stored at low temperature. The existing RFID technology can contain the information of the expiration date, but it cannot reflect the information of the premature expiration and failure of the medicine due to improper storage.
Inadvertent use of invalid medical products may lead to serious accidents

Abstract

The invention discloses an electronic tag combining a time-temperature indicator and radio frequency identification. The electronic tag comprises a substrate layer, a reaction layer which is adhered to the substrate layer, an RFID (Radio Frequency Identification) transponder which is connected with the reaction layer, and an activator which is used for activating the reaction layer, wherein the substrate layer is made of transparent material; the reaction layer is a conductive polymer film; the activator is an electrolyte solution. The electronic tag prepared by the invention is capable of recording the time-temperature changing process of the products to be indicated through the time-temperature indicator, tracking and recording various information of the products to be indicated through the RFID transponder, and automatically closing the RFID transponder after the products to be indicated exceed the expiration date, thus effectively preventing the continuous use of the expired or invalid products.

Description

technical field [0001] The invention relates to an electronic label, in particular to an electronic label with a time-temperature indicator and a radio frequency identification. Background technique [0002] The shelf life of food or medicine is the quality assurance period of prepackaged food or medicine under specified storage conditions. During this period, the product is fully fit for sale and retains its characteristic qualities which need not be stated or have been stated on the label. Through the shelf life, consumers can know the quality status of the purchased products, and manufacturers can specify the correct distribution channels and sales models. [0003] However, the temperature of food or medicine is unpredictable during the entire storage and transportation stage, so the printed date cannot truly reflect the quality of the product. For example, some food or medicine that needs to be refrigerated is not used in the transportation process. It will cause food ...
