An implantable microphone for a hearing prosthesis. The microphone comprises: a housing having a diaphragm chamber formed therein, and an aperture extending from the exterior surface of the housing to the chamber; a diaphragm disposed on the exterior of the housing so as to seal the aperture, and configured to vibrate in response to sound signals; a sensor positioned adjacent an end of the chamber opposing the diaphragm, and configured to detect vibration of the diaphragm, and to generate electrical signals based thereon; and a stiffening material substantially filling the regions of the housing external to the sensor and the diaphragm such that that air gaps within the filled regions of the housing are substantially eliminated, wherein the stiffening material has an elastic modulus that enables the housing to substantially resist deformation there of in response to body-noise.

A method for attaching imagers to color-separation prisms includes the steps of: arranging three solid-state array image sensor integrated circuits behind and in close proximity to the output faces of a color-separating prism having substantially equal optical path lengths for the three paths, the three solid-state array image sensor integrated circuits each having a solid-state array image sensor and bonding pads for electrical connections disposed on a top face thereof; aligning the three sensors such that the images traversing the three paths are coincident within a pixel dimension of the image sensors; filling the space between each output face of the prism and the top face of the corresponding image sensor with index-matched adhesive; and causing the index-matched adhesive to become rigid while maintaining the alignment of the three image sensors.
