Piezoelectric signals of HAp and collagen with different glucose concentrations: A method for diabetes detection.

Piezoelectric signals were obtained from samples based on hydroxyapatite (HAp) and collagen (C) containing different glucose (G) concentrations. HAp was obtained by coprecipitation using Ca and HPO as precursor ions in solution. C and G were added at the beginning of the coprecipitation method during the HAp growth.
