It seems that new thin-film transistors will be revolutionary for the first time in the field of detecting the shelf life of food, which can display the best expiry date of food, which is more valuable than some display pictures or electronic tattoos.
At present, this kind of nano-material graphene through 2D printing technology can be used in newspapers, commodity price labels and other fields, and this kind of electronic label is currently to be widely used in the commercial field, and it still needs many more years of development.
Coleman and his team have developed this type of transistor by 2D printing nanomaterials. In other words, this type of electronic label based entirely on planar printing is very low cost and can have many different uses.
For example, this kind of electronic label can be used to replace the traditional paper label in the supermarket, and the use of this technology no longer has to manually change the new price. This kind of electronic label can be controlled by a computer to automatically update the price. It can even be used on personal citizen passports and packaging of wine and milk to display the date of production. You can even create newspapers, posters, and books that can change the content like Harry Potter.
At present, this technology is still in the testing stage, and specific new results and processes will be gradually announced in the future.
