  • Method for producing a piezoelectric film
    Patent number: 8372469
    Abstract: A method for producing a biocompatible material of the formula NaxKyNbO3, 0?x?0.8, 0.2?y?1, x+y=1 includes the steps of a) providing a Na-precursor and a K-precursor for NaxKyNbO3, b) mixing the precursors in solution wherein said precursors first react to form a sol and thereafter a gel, c) heat treating the gel to obtain an oxide of the material NaxKyNbO3, 0?x?0.8, 0.2?y?1, x+y=1. The material can be produced as a film, and the material or film can be provided on the exterior surface of a medical implant that will come into contact with body tissue and/or body fluids upon implantation thereof.
