Piezoelectric nanogenerators made from spider silk

Thu, 06/14/2018 - 10:04
Spider silk fibers show nature's most outstanding mechanical properties, for example, excellent tensile strength and elasticity, and remarkable protein sequence structure. So far, it has remained completely unidentified how the mechanical properties of spider silk fibers effectively contribute to the performance of a piezoelectric nanogenerator. Now, researchers have successfully demonstrated by Piezoresponse Force Microscopy experiment that natural spider silk fibers have a definite vertical (out-of-plane) piezoelectric coefficient.
