20110015555 | PIEZOELECTRIC, MICRO-EXERCISE APPARATUS AND METHOD - An apparatus and method for micro-exercise apply piezoelectric stress to cells of a bone mass by inducing voltages in the bone mass. Application of dynamic, electromagnetic fields passing through the conductive bone mass induce currents and voltages locally in and around cells or groups of cells.
