| 摘要 |
The invention relates to an implantable microphone, comprising a source (32) of incoherent light (34), a light detector (38) for outputting a signal corresponding to the total light intensity impinging onto a detector surface (42), a housing (26) for housing the light source and the detector, and a sensor membrane (28) for being exposed to surrounding soft tissue, the membrane being arranged to seal an opening of the housing and comprising reflector means (36) provided at the inner side of the sensor membrane for reflecting light from the light source onto the detector in manner that the total light intensity reflected onto the detector varies as a function of the position of the reflector means relative to the detector. |
