"electrical signals are key to normal growth... tissue scaffold made out of nanofibers of poly-L lactic acid (PLLA), a biodegradable polymer often used to stitch up surgical wounds. The nanomaterial has a neat property called piezo-electricity. When it is squeezed, it produces a little burst of electrical current The team recently tested the scaffold in the knee of an injured rabbit... the cartilage grew back normally"
