A piezoelectric model for dry bone tissue.

Abstract A linear theory of piezoelectric bars is used for analyzing a dry femur under constant load and a cantilever dry bone beam subjected to a vertical end load. The results obtained from this theoretical study are: (a) The faster healing of the fractured bone tissue by the aid of negative electrical surface charge; (b) The causes of the cellular level electrical stimulation due to the alternating structure of the collagen fibers in the osteons; (c) The faster rate of remodelling of the bone tissue due to the shear force.
