ABSTRACT:
A miniature, hybrid-mountable, accelerometer-based, physical activity sensor for use with a rate-responsive implantable stimulation device is provided. The physical activity sensor is constructed as a cantilever beam having a film of a piezoelectric polymer adhered to each surface of an electrically conductive substrate. The piezoelectric films are highly resistant to fracturing during manufacture and in use, and they provide a strong output signal when stressed in response to bodily accelerations. A pair of electrically conductive supports serve to anchor the physical activity sensor to a substrate and deliver the output signal provided by the sensor to circuitry within the rate-responsive implantable stimulation device. The physical activity sensor is adapted to be mounted directly to conductive traces on a suitable substrate, preferably an implantable stimulation device hybrid.
