New electrical stitches use muscle movement to speed up healing

In an experiment in rats, rodents treated with the electric stitches made a quicker recuperation and were much less most likely to develop an infection than rats treated with typical sutures and unattended rats.

The string is made from biodegradable polymers and magnesium, a metal that can be absorbed by the body over time. When muscular tissues around the stitches agreement and relax, the thread’s center layer massages versus the external covering, transferring electrons to the covering and generating electrical energy.

Scientists already recognized that pumping electrical power through stitches might speed up recovery, but previous innovations relied on cumbersome exterior batteries. The brand-new sutures are powered by the body itself (SN: 3/2/23).
