On a wireless power transmission system for an implantable prosthesis telemetry unit

We propose a wireless electrical power transmission system, for energizing a stress monitoring arrangement on the surface of a Titanium based-alloy prosthesis implant. Applying standard methods for characterizing cylindric coils, we find a frequency range that warrants the maximum power transmission, and we propose an electronic circuit for transmitting the sensed values by virtue of radio waves. We also mention some unexpected phenomena of power transference at very low frequencies.
