PIEZOELECTRIC SENSOR, A METHOD FOR MANUFACTURING A PIEZOELECTRIC SENSOR AND A MEDICAL IMPLANTABLE LEAD COMPRISING SUCH A PIEZOELECTRIC SENSOR

摘要

In a piezoelectric sensor, a method for the manufacture thereof, and an implantable lead embodying such a piezoelectric sensor, a layer of piezoelectric material, having aligned, polarized dipoles, is applied to a tubular supporting substrate, the layer of piezoelectric material having at least one electrode at an outer surface thereof and at least one electrode at an inner surface thereof. The piezoelectric material is applied on the inner circumference of the tubular supporting substrate.
