Abstract
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.
