Why do many scientists consider using graphene materials for electronic tattoos?

Because of this tattoo-style electronic **, the biosensor is required to have good flexibility, scalability and high sensitivity, as well as wearing comfort, and the flexibility of graphene can be highly compatible with **, which also greatly increases the accuracy of measurement. The sensor was developed by researchers at the University of Texas at Austin, who hope that the ultra-thin sensor could be used in the beauty market or even replace existing medical testing equipment, <>

For example, the graphene electrode thickness in the graphene tattoo sensor at the University of Texas is only nanometers, which can better read the changes caused by changes in electrical activity in the epithelial tissue, while the larger electrodes of general medical monitoring equipment are prone to voids during stretching and contraction, thereby reducing signal accuracy.

So far, we have seen a lot of demos of electronic tattoos, but there is no official product on the market, which inevitably makes people wonder if it is another concept product in the laboratory.

As mentioned earlier, the need to be ultra-thin to fit ** and to cram an integrated circuit that can collect various biological signals in such a small space puts very high demands on electronic components.

Notably, Stanford University's Zhenan Bao team published a new technology in the journal Nature last year that allows components to be stretched twice as much without losing conductivity and sensitivity, making it possible to mass-produce this new flexible and scalable electronic component. As Bao Zhenan said:

This proves that it is an achievable thing to make electronic devices with electronic materials like electronics, and it is no longer a science fiction dream.

This means that the commercial application of electronics may not be far away.

Graphene is an ultra-thin material with excellent flexibility and conductivity, making it an ideal material for electronics.

Graphene electronic tattoos, developed by scientists at Tsinghua University in China, can be easily transferred to different surfaces such as human bodies**, leaves, and silk.

Electronic tattoos have high sensitivity and long-term stability. It has been reported to withstand higher temperatures and does not interfere with normal activities when worn.

This material is very special and very functional.

Maybe the cost will be very low.

Graphene is a good source of energy, very good.

It can withstand high temperatures and does not interfere with normal activities when worn.

I can't figure out why I have to get a tattoo.

The growth of plants is inseparable from water, but different plants have different water needs, so how can we effectively master this degree in the daily cultivation process? This often requires the teaching or experience of others, but researchers from Iowa State University have found a new way to use a strip humidity sensor made of graphene that attaches to the leaf to know how much water is needed.

The project, led by Professor Liang Dong, first creates a specific row of patterned notches on the surface of a plastic block, and then fills the notches with a liquid solution containing graphene. After the solution has dried, place another layer of tape on the leaves.

Dong said that this method of processing is very simple, and the production cost is very low. By measuring the conductivity of these strips, the research team was able to measure the amount of water needed by the leaves of the plant, and the more conductive they were, the more water they needed. This technology has already been successfully tested on cereals.
