Stanford scientists create highly flexible electrodes


In fact, there are already flexible electrodes for some years, however, the numbers attest that this is the one that offers better conditions of conduction of electricity and of light transmission.

For the integration of this technology into everyday objects, it is essential that circuits become flexible, flexible and adaptable to the conditions of the destination that we want to assign them. At Stanford University, more specifically in the Zhenan Bao laboratory, there is a team of dedicated scientists who have been able to create a highly flexible electrode, “which does not compromise electrical performance” and which has a secret from industrial kitchens. The flexibility of this component was only possible thanks to something very banal and an integral part of the daily life of the human being: soup.

Mostly composed of plastic, a material that is not a good conductor of electricity. Ainsa thus, Bao and the rest of his team created a plastic electrode with good driving ability thanks to the use of two different polymers. This addition limited, to some extent, the flexibility of this component. Thus, the solution to the problem arose at the SLAC National Accelerator Laboratory, where, thanks to unique x-ray equipment, the scientists concluded that the missing element in this electrode was, after all, a molecule in an ingredient used in kitchens to make soups thicker.

“Actually, the level of electricity conduction even increases when the material is stretched”, Bao said, adding that the conduction and light transmission figures presented with this experiment are the best ever recorded on transparent electrodes and flexible materials.

That is, the possible real applications of this innovation are very extensive. According to the scientist, it is possible that material such as this will be included in brain activity monitoring devices, smart clothing with heart rate sensors and even in epidermal implants.
