A novel high performance induction link for hearing implants
Research Project, 2022
Purpose and goal
The objective of this project is to investigate the potential for a new generation, high performance, bone conduction implant system based on novel transducer and power link technologies. The main tasks will be to conceptualize and evaluate transducer electronic driver stage, to develop methodologies for evaluation and optimisation of the energy link and to evaluate the output performance of the system. Also, the influence of design and material parameters of the power link in relation to the novel transducer technology will be determined.
Expected results and effects
The project is expected to conceptualize, evaluate and build a transducer driver stage and to determine the effects of different parameters. The power link will be evaluated, adapted and optimised for driver/transducer system. Preliminary results show that the coupling factor of the novel power link is substantially higher compared with a conventional planar-coil link and the output performance of a complete system is expected to outperform current available solutions. The driver stage and power link is expected to reduce current consumption and extend battery life.
