Important results from the project
The project´s objective was met by developing and evaluating a technology that improves the power transmission of today´s implanted bone conduction hearing aids with the aim of improving sound quality and helping more patients who are suffering from hearing loss. The collaboration between academia and industry resulted in new technical solutions and concepts that can be implemented to efficiently and with low power consumption drive vibrators and the new generation speaker technologies compatible with magnetic resonance imaging.
Expected long term effects
The project resulted in a completely new concept that can be implemented in the company´s products. Despite low power consumption, the hearing implant becomes as efficient as many commercial alternatives used successfully worldwide which are not compatible with magnetic resonance imaging. The project has resulted in a patent application and the results are also planned to be published in a scientific journal and presented at conferences. The mobility project has resulted in new competitive ideas and long-term continued collaboration between the parties.
Approach and implementation
To achieve the project´s objective, the project manager has worked 50% at Oticon Medical for a total of 18 months together with experts in the research & development department. Ideas and concepts have been evaluated through calculations, simulations, electronics design, prototyping and measurements. A joint patent application has been submitted and the results are expected to be submitted to the appropriate journal. Parts of the project have been examined in a degree project at Oticon Medical supervised by the project participants and examined at Chalmers Tekniska Högskola.
