Abstract
A piezoelectric bio-organic films resembling ceramic-based piezoelectric films, and also a fabrication method thereof. In particular, the bio-organic piezoelectric films are formed by compact nanocrystals resembling the inorganic ceramic structure, where nanocrystallization on biomaterials and in-situ electric field are applied to facilitate domain orientation alignment across the entire films. The present fabrication method provides flexibility to tune various parameters of the resulting bio-organic films according to the needs, and therefore is substantially applicable to a wide range of biomaterials to form piezoelectric bio-organic films comparable to those formed by conventional piezoceramics in terms of piezoelectricity, thermostability and durability.
