Scientists with the Bao Research Group at Stanford University have created a new electronic skin that can mimic the sense of touch. The “e-skin,” as some refer to it, is detailed in a new study featured in the journal Science. The skin is intriguing because it is not only soft and stretchable, but it can also generate nerve-like impulses that communicate directly with the brain.
Previous attempts to make skin like this have required very rigid electronics in order to convert the sense of touch and other nerve-like signals. However, these researchers have managed to not only convert senses like pressure or temperature into electrical signals, but they’ve also managed to do it with a very thin, stretchable material that can be applied almost anywhere.
The resulting electronic skin has already known immense success during the researcher’s study. Zhenan Bao, a senior author of the study, says mimicking the sense of touch wasn’t the difficult part. “The hurdle was not so much finding mechanisms to mimic the remarkable sensory abilities of human touch,” Bao explained in a statement. The trouble, instead, lies in bringing all those components together using nothing but skin-like materials.

The skin relies on layers of technology like a soft integrated circuit that mimics the sensory receptors found in human skin. This circuitry relies on a very low voltage to run efficiently, requiring only five volts. The researchers say that this kind of electronic skin will be vital to create new-age prosthetic limbs that not only help restore movement functions but also help provide sensory feedback.
It’s definitely a far cry from earlier tech like Facebook’s touch glove, which let you experience touch in virtual reality, and hopefully, future research and development brings some widespread availability of this kind of technology for those who need it. Similar tech developed in Singapore could also help push this next generation of prosthetics.
