1. A sensor device for applying a sensor to a medical device, the sensor device comprising:
a flexible planar strip configured to at least partially encapsulate the medical device, the flexible planar strip comprising:
a first dielectric layer;
a second dielectric layer;
a patterned conductive layer disposed on the second dielectric layer, the patterned conductive layer including a sensor electrode disposed at a distal end portion of the patterned conductive layer, a hub electrode disposed at the proximal end of the patterned conductive layer, and a trace connecting the sensor electrode and the hub electrode;
an ultrasound sensor disposed on the sensor electrode, a first surface of the ultrasound sensor configured to make electrical contact with the sensor electrode and a second surface of the ultrasound sensor exposed for making electrical contact with the medical device; and
a third dielectric layer formed on the patterned conductive layer, wherein a distal end portion of the third dielectric layer is recessed to expose the sensor electrode and a proximal and portion of the third dielectric layer is recessed to expose the hub electrode.
