US 12,726,776 B2 · Intraoperative vibrational feedback assessment

Abstract

Presented herein are techniques for generating information characterizing an amount of vibration isolation between an implantable vibration sensor and an implantable mechanical actuator (actuator), when each are implanted in a recipient. In particular, the implantable mechanical actuator is configured to generate and deliver, based on one or more actuator control signals, mechanical stimulation signals to the recipient. The vibration sensor is configured to capture vibrations induced by the delivery of the mechanical stimulation signals to the recipient. A vibrational transfer function relating a position of the vibration sensor to the actuator is then generated based on the captured vibrations and the attributes of the actuator control signals. The vibrational transfer function provides an indication of the vibration isolation present between the vibration sensor and the actuator, at their respective locations within the recipient.
