Local piezoelectric activity of single poly(L-lactic acid) (PLLA) microfibers
Local piezoelectric properties of the poly(L-lactic acid) individual electrospun fibers have been studied by Piezoresponse Force Microscopy. Piezoelectric response, polarization switching, and nanoscale patterning of the fibers have been demonstrated in this important biomaterial, thus opening interesting possibilities for tissue engineering and sensing/actuating applications.
