Methods, devices, and systems for measuring vibration of an implanted elongate vibrating body coupled to a bone of the middle ear. One system includes an elongate vibratory body having a first and second piezoelectric body separated by a central vane. The piezoelectric bodies and central vane can be individually electrically coupleable to an implantable electronic device. The electronic device can have a switch, driving circuitry and sensing circuitry within. In normal use, the driving circuitry is coupled through the switch to drive both piezoelectric bodies causing the vibratory body to vibrate. In diagnostic use, one piezoelectric body is driven while the other piezoelectric body is sensed to detect changes in vibration indicative of decoupling or undesirable impedance of the vibratory body.
A method for measuring the vibration of an implanted elongate vibrator body coupled to a bone of a middle ear, where the elongate vibrator body includes at least a first and a second piezoelectric body each disposed on opposite sides of the elongate vibrator body, where the first and second piezoelectric bodies are individually electrically connectable with respect to each other, so as to allow forcing vibration of the elongate vibrator body by electrically driving the first and second piezoelectric bodies from an electrical excitation source at a desired frequency, and allowing measuring vibration from the second piezoelectric body using an electrical sensing circuit, the method comprising:
