Measuring device for the mechanoelectric measurement and monitoring of physiological activities in an electrically evoked stapedius muscle tissue (eKEHRT sensor)
The invention relates to a measuring device for measuring and monitoring physiological activities in an electrically evoked stapedius muscle tissue (eKEHRT sensor), in particular for contactless measuring of physiological activities of electrically evoked tissue which is located in the human middle ear, which consists of a biocompatible sensor element (1), wherein the biocompatible sensor element (1) is arranged at or on or around a movable structure in the cavum of the middle ear using a corresponding fastening element (4), and connected via a discharge electrode (5) to the cochlea implant (not shown), and the round magnet (6) for producing a magnetic field is inserted in the cochlea implant for fastening the external speech processor. An additional mini coil (7), which increases the sensitivity of the sensor element (1) and makes adjustment of the sensor element (1) easier, is integrated on or in the discharge electrode (5) or fastened in a bone window the middle ear cavity.
