Tiny electric generators could accelerate wound healing

TSUKUBA, Japan, Jan 18, 2022 - (ACN Newswire via SEAPRWire.com) - Tiny dressings that generate electricity in response to movement could accelerate wound healing and tissue regeneration. Scientists in Taiwan reviewed the latest advances and potential applications of wound healing technology in the journal Science and Technology of Advanced Materials."Piezoelectric and triboelectric nanogenerators are excellent candidates for self-assisted wound healing due to their light weight, flexibility, elasticity and biocompatibility," says bioengineer Zong-Hong Lin of the National Tsing Hua University in Taiwan.The natural wound healing process involves complex interactions between ions, cells, blood vessels, genes and the immune system; with every player triggered by a sequence of molecular events. An integral part of this process involves the generation of a weak electric field by the damaged epithelium - the layer of cells covering tissue. The electric field forms as a result of an ion gradient in the wound bed, which plays an important role in directing cell migration and promoting blood vessel formation in the area.Scientists discovered in the mid- to late-1900s that stimulating tissue ...
