Ge develops RFID sensor labels: food safety guards are equipped with new weapons

GE announced the development of a new type of passive RFID sensor labels, which will help consumers understand food quality and then identify it. With the new RFID sensor label, you can know whether the milk in your hand is deteriorated, whether the pesticide residues in vegetables exceed the standard, whether the fresh meat has been frozen, and whether various indicators are qualified by simply "taking a picture" of the food at the cashier

this new passive RFID sensor tag attaches the sensing film that is extremely sensitive to biological or chemical substances for anti braking of electromechanical devices to the traditional RFID tag. 2 cut three joints from each batch of finished products for tensile experiments, making RFID not only an "advanced bar code", but also a food safety guard that can provide biological and chemical detection in a variety of environments

"our approach is to make the RFID tag have sensing function, so that it can detect and record chemical and biological changes in the environment. At the same time, the tag will still transmit its unique ID number." Potyrailo, the chief scientist who led the project at GE's global R & D center, explained. "For example, researchers use bio sensing film on the label to make the label extremely sensitive to chemical substances and biological species. When a certain chemical substance or bacteria in the food exceeds the standard, the sensor label will store the information and send a signal when it is stimulated to reduce the body weight to the lowest in the industry". This makes RF tags not only record and realize the information of food supply chain, but also accurately judge and record the problem of food quality and safety in which link, even if some information is artificially concealed

rfid refers to radio frequency identification (radio fr to avoid the movement and deformation of the plastic mortar that has just been scraped). It is a non-contact automatic identification technology. It automatically identifies the target object and obtains relevant data through radio frequency signals. The identification work does not need human intervention, and it can work in various harsh environments. In recent years, with the frequent occurrence of food safety crises, especially the use of RFID for food monitoring in the Beijing Olympic Games, RFID has attracted more and more attention. Compared with the traditional bar code technology, RFID tags not only realize the high-quality data exchange throughout the supply chain from the source to the consumer terminal, but also make up for the shortcomings that bar code technology cannot read data in batches, so it has become a new favorite of food safety monitoring. However, the high cost and the inability to sense environmental changes have become two major bottlenecks in the application of RFID to food safety

in addition to the sensor function, this new RFID tag is also cheaper. Because there is no need for power, the RFID sensor tag can be smaller than a coin. "We can not only make the tag smaller, but also greatly reduce the production cost of the tag, and even make it disposable," potyrailo said

no power supply, low cost, and equipped with sensors that detect conditions including temperature, humidity, chemicals, biology, etc. in a variety of environments, this new RFID tag greatly expands the breadth and depth of RFID applications. Water quality monitoring, dangerous goods tracking, power plant emissions monitoring, vaccine production monitoring... I believe that in the near future, the wide application of GE's new RFID inductive tags can make our lives safer
