A team of engineers from Stanford University in California has created a plastic material that recognizes pressure, delivering a signal straight to a living brain cell. They say their work serves as a step toward creating artificial limbs with the sense of touch.
The engineers, led by Prof. Zhenan Bao, publish their work in the journal Science.
Prof. Bao has been working for a decade to develop a material that can imitate the skin’s ability to flex and heal, as well as send signals to the brain that represent touch, temperature and pain. Her end goal is to create a flexible fabric laced with sensors that cover an artificial limb and copy some of the skin’s senses.
