摘要： A headpiece for a cochlear implant system includes a transcutaneous transmission coil that transfers power and/or data to an implantable device implanted under a user's skin. The headpiece includes a magnet for holding the transmission coil in close proximity to the receiver coil in the implanted device, which also contains a magnet, and provides the desired alignment between the coils so that inductive coupling may efficiently occur. The headpiece has a bottom surface for skin contact that includes a plurality of flexible bumps configured to distribute pressure over a large surface area while allowing blood flow throughout the area. This also provides friction contact with the skin to help secure the headpiece, reducing movement due to lateral loading, while reducing skin irritation and erosion.
