Zusammenfassung:A mechanically actuated transmitter is disclosed. The transmitter can comprise a magnetoelastic member; a magnet adjacent to the magnetoelastic member for inducing magnetization in the magnetoelastic member; a mechanical driver for applying mechanical stress to the magnetoelastic material, thereby changing the magnetic permeability of the magnetoelastic material to change an external magnetic field.
