Scientists create surgical stitch to aid healing by electrical stimulation

Researchers in China say their suture can speed up wound healing and reduce risk of infection by producing a charge

The humble stitch plays a crucial role in surgery, holding a gash together while tissues repair. Now scientists have created a type of suture they say can help speed up wound healing and reduce the risk of infection.

Researchers in China have created a suture that when put under strain - as occurs during movement - electrically stimulates the wound.
