This study aims to present the HUCI and compare the test results with the existing fully implanted cochlear implant concepts(FICI) . Methods: BLE module was implanted in the implant bed. For the TODT tests, a receiver was passed through the posterior tympanotomy, and the transmitter was placed in the ear-canal. Results: The BLE range was 5.2-17.5m. TODT reached 1Mbit/s rate and 99.22% accuracy. Despite various obstacles, the accuracy of the TODT was 99% with 250Kbit/s rate. The average power consumption was 310mW for the implanted BLE module and 41mW for the TODT receiver. Conclusion: BLE is suitable to be used transcutaneously. TODT is an effective and promising technology. HUCI aims to have the esthetics of a FICI with higher reliability, a magnet-free design with smart device integration.
