Analytical solution of electro-mechanical wave propagation in long bones

摘要

In this work, analytic solution of electro-mechanical wave propagation in a long bone has been obtained. A dry long bone is considered as a piezoelectric transversely isotropic hollow cylinder, for stress wave a flexural mode for n=1,2 is studied. The dispersion curve is plotted. The generated electro-magnetic fields as a function of cylindrical coordinates are obtained, and then the components of the magnetic field are plotted. Theoretical results are compared with the in vitro experimental values as measured by a previously developed non-contacting electromagnetic device.
