Chinese scientists have developed a new material that they say will improve the performance of prosthetic devices.
The authors of the new study used ion-conductive materials in their technology, rather than electrical conductors, which are not always compatible with the human body.
The new ionic organohydrogel contains a moleculespiropyran. Under mechanical stress, it changes color from pale yellow to bluish-violet. A special gel has become the mainstream of artificial skin called I-skin. It has already been tested by attaching it to various body parts of volunteers - fingers, hands and knees.
In the course of experiments, scientists have shown that theirI-skin flexes and stretches without bruising. But strong and repetitive pressing, bumping and pinching really changed the color of the material: purple remained on the surface of the artificial leather for two to five hours before it returned to its original color.
The study was published in the journalACS Applied Materials & Interfaces
