A hand robot It may allow doctors to more accurately diagnose and treat people on the other side of the world, but the technology currently available is not good enough to match the experience of being on site in person.
Some researchers now reports in the journal Science Advances who has designed and produced one smart electronic skin and a medical robot hand capable of evaluating vital diagnostic data using a newly invented rubber-like semiconductor that enables high mobility carrier.
Cunjiang Yu, an associate professor of mechanical engineering at the University of Houston and co-author of the paper, said the material semiconductor gumoso can be easily scaled for manufacturing.
The interface unit and rubber-like electronic devices described in the paper suggest a path to soft and elastic rubber-like electronics and embedded systems that mimic the mechanical softness of biological tissues, suitable for a variety of emerging applications, says Yu, who is also Principal Investigator at the Texas Superconductivity Center UH.
Smart skin and the medical robot hand are just two potential applications, created by researchers to illustrate the benefits of the discovery.

In addition to Yu, the authors of the work include Ying-Shi Guan, Anish Thukral, Kyoseung Sim, Xu Wang, Yongcao Zhang, Faheem Ershad, Zhoulyu Rao, Fengjiao Pan and Peng Wang, who are all affiliated with UH. Co-authors, Jianliang Xiao and Shun Zhang, are affiliated with the University of Colorado.
The semiconductor Traditional ones are brittle, and their use in stretchable electronics has required special mechanical adaptations. Previously stretchable semiconductors have had their own disadvantages, including low carrier mobility – the speed at which charge carriers can move through a material – and complicated manufacturing requirements.
Yu and his staff reported last year adding small amounts metallic nanotubes in carbon to rubber-like semiconductors of P3HT – polydimethylsiloxane compound – improves carrier mobility, which controls the performance of semiconductor transistors.
Yu said the new scalable manufacturing method for these high-performance extensible semiconductor nanofilms and the development of fully rubber-like transistors is an important step forward.
Production is simple, he said. A commercially available semiconductor material is dissolved in solution and dropped into water, where it disperses; the chemical solvent evaporates from the solution, resulting in an improvement in the properties of the semiconductor.
It’s a new way to create high-quality composite films, he said, enabling consistent production of completely rubber-like semiconductors.
Electrical performance is maintained even when the semiconductor is stretched 50%, the researchers reported. Yu said the ability to stretch rubber-like electronics by 50% without compromising performance is a remarkable step forward. Human skin, he said, can be stretched only 30% without tearing.
