Abstract
It is shown that the electromechanical behavior of bone in cantilever bending, in which the signal is related to the stress gradient, can be viewed as a consequence of a variation of a piezoelectric modulus along this gradient. Such behavior can be duplicated by piezoelectric ceramics if they are fabricated to exhibit the appropriate spatial variations. Theoretical expressions are obtained and confirming experimental data are presented for the piezoelectric response to cantilever bending of two such special cases — a ceramic bimorph and a radially-poled hollow cylinder. The former contains the essential piezoelectric texture to mimic a thin slab of bone, and the latter models a whole bone.
