This paper presents the use of Class-E oscillators as inductive power transmitters for implanted telemetry devices that transmit information sensed by biosensors. Several Class-E oscillators are compared with an equivalent Class-E amplifier, showing higher efficiency while maintaining frequency clarity, stability and accuracy. Energy has been successfully transferred to a receiving inductor 1.5 cm away, which has been rectified to produce a 1 V<sub>DC</sub> signal
