The disclosure relates to an implantable sensor (1) for the detection of an electric excitation of muscle cells (M), more particularly heart muscle cells (M), wherein, according to the invention, the sensor (1) has a dielectric component (2) and a contact point (20) for contacting muscle cells (M), said contact point being connected to the dielectric component (2) such that, in the event of an electric excitation of the muscle cells (M), an electric field in the dielectric component (2), and thus a capacitance of the dielectric component (2), changes. A system comprising a sensor and an implant is also disclosed. |
