A new type of synthetic “skin” is the first material that can both sense subtle pressure and heal itself when torn or cut. The advance, described in the journal Nature Nanotechnology, could lead to smarter prosthetics or resilient personal electronics that repair themselves. In the last decade, there have been major advances in synthetic skin, says Zhenan Bao, the study’s principal investigator and a chemical engineering professor at Stanford University, but even the most effective self-healing materials had major drawbacks. Some had to be exposed to high temperatures, making them impractical for day-to-day use. Others could heal at room temperature, but repairing a cut changed their mechanical or chemical structure, so they could heal themselves only once. Most important, no self-healing material was a good bulk conductor of electricity, a crucial property. “To interface this kind of material with the digital world, ideally you want it to be conductive,” says Benjamin Chee-Keong Tee, a researcher on the project.
