An exponential law is presented for modeling piezoelectric behavior of bone tissues. The law is established based on experimental observation and existing empirical decay function. The model is then used to investigate the relaxation behavior of pizeovoltages induced by external load. Piezovoltages between the two opposing surfaces of bovine tibia bone samples under three point bending deformation are measured using an ultra high input impedance bioamplifier. The experimental results indicate...[Show more]
