Abstract

Disclosed is a method to use the accelerometer(s) in a smart phone to detect the device functionality of an osseo-integrated vibrator. Stimulation of the implant is sent wirelessly from the smart phone to the recipient's sound processor.

Title

Smart phone-based evaluation of an osseo-integrated vibrator

Abstract

Disclosed is a method to use the accelerometer(s) in a smart phone to detect the device functionality of an osseo-integrated vibrator. Stimulation of the implant is sent wirelessly from the smart phone to the recipient’s sound processor.

Problem Addressed 

Evaluating the device functionality of any type of (auditory) implant during and after surgery is crucial, as it is often used as a risk control or required by the regulators. Measuring the device functionality of an osseo-integrated vibrational implant once it is implanted can be complicated because there is no direct access to the implant.

Known Solutions/Approaches

One solution to measure this device functionality for recent types of acoustic hearing implants, is the use of impedance measurements (i.e., actuator current consumption).  This is not a viable solution because the measurement resolution is currently too low; the intra-operative test requires the use of an actuator isolator to allow the detection of partially damaged implants. In addition, this measurement technique currently involves the use of a laptop with a dedicated software application.

Novelty Statement

The novel solution is a method to use the accelerometer(s) in a smart phone to detect the device functionality of an osseo-integrated vibrator. Stimulation of the implant is sent wirelessly from the smart phone to the recipient’s sound processor.

Description (Components, Process)

Smart phones include one or more sensitive accelerometers to sense the tilt and movement (including speed) of the device. These accelerometers also enable smart phones to detect the vibration of a device that is in contact with the smart phone. By placing the smart phone over the implant (i.e., vibrator) site and stimulating the implant with a known stimulus, the generated vibrations can be picked up with the smart phone and evaluated using a dedicated smart phone application.
