The optimisation of inductive telemetry link for increasing wireless range of a medical implant device is studied in detail. An active implant device using separate wireless power and data links at 2 MHz and 420 kHz has been fabricated and tested. A test setup consisting of RF power transmitter and data reader hardware has been implemented. Measurement results show that the fabricated device achieved a wireless range of 25 cm.
