摘要

Sutures, as necessary medical devices for postoperative treatment, are no longer merely supportive but are required to have advanced functions to promote repair. Here, we report an absorbable self-powered electrical stimulation suture. The suture is composed entirely of absorbable materials (magnesium, polylactic acid, and polycaprolactone) and can be used in vivo for incision closure and repair. The suture has the capacity to generate spontaneous electrical stimulation in response to body movement, allowing for accelerated tissue reconstruction. An in vivo muscle incision repair model demonstrated that the wound healing rate under treatment with this suture was 1.6 times faster than that of commercial sutures, proving its postoperative therapeutic capability.
