  • Accelerometer for implantable medical device
    Patent number: 6216537
    Abstract: An accelerometer device which can be mounted on a substrate, e.g., a circuit board enclosed in a medical device, includes an accelerometer sensing element having an axis of sensitivity and further includes first and second multilayer end caps. The substrate generally defines a mounting plane. The accelerometer sensing element includes a device body having a longitudinal axis extending between generally parallel first and second ends thereof and further includes a principal surface extending between the first and second ends of the device body parallel to the longitudinal axis. The axis of sensitivity of the sensing element is generally perpendicular to a plane defined by the principal surface. Further, the accelerometer sensing element includes conductive pad regions on each of the first and second ends of the device body.
