Bioelectronic options for a totally implantable hearing device for partial and total hearing loss.
A semi-implantable electromagnetic hearing device (SIMEHD) for sensorineural hearing loss has been developed and tested in animals and limited clinical trial. The authors' electromagnetic transducer, which is the driver of the SIMEHD, when used in reverse mode is applicable to the fabrication of a bioelectronic microphone. Instead of being a driver, it transforms the sound-activated eardrum-ossicular vibration into an electric signal through the NdFeBo magnet implanted on the head of the malleus, interacting in a contactless manner with the electromagnetic coil.
