Wound Healing With Wearable Nanogenerators

According to University of Wisconsin–Madison engineers, a new, low-cost wound dressing could improve healing times by a factor of three or more.

Researchers have known for several decades that electricity can be beneficial for skin healing, but most electrotherapy units in use today require bulky electrical equipment and complicated wiring to deliver powerful jolts of electricity...

The new dressings consist of small electrodes for the injury site that are linked to a band holding energy-harvesting units called nanogenerators, which are looped around a wearer’s torso. The natural expansion and contraction of the wearer’s ribcage during breathing powers the nanogenerators, which deliver low-intensity electric pulses.

Fans of Frank Herbert may be thinking of the Atlotl/Gibiril Regimen described in his 1972 novel The Godmakers; it uses the body's own energy to regrow lost tissue.
