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

摘要

The invention relates to a piezoelectric sensor comprising a layer of a piezoelectric material (3) , having aligned, polarized dipoles, which is applied to a tubular supporting substrate (2) , and having at least one electrode (2) connected to its outer surface as well as at least one electrode (5) connected to its inner surface. The piezoelectric material (3) is applied on the inner circumference of the tubular supporting substrate (2) . The invention also relates to a method for manufacturing a piezoelectric sensor and a medical implantable lead comprising such a piezoelectric sensor.
