Abstract
The present invention relates to accelerometer assemblies for implantable medical devices such as pacemakers, IPGs, PCDs, defibrillators, ICDs and the like. The accelerometer assembly of the present invention comprises a beam that deflects in response to being subjected to an externally provided force. Deflection of the beam generates a voltage in a piezoelectric material disposed in the assembly. At least one stop is provided to limit the vertical range of motion through which the beam may deflect to prevent failure, fracturing or breakage of the beam resulting from excessive deflection of the beam that might otherwise occur were the stop not present.
