1. A flexible circuit, comprising:
a first planar segment comprising a plurality of teeth arranged in a geared pattern and a plurality of holes disposed entirely through the first planar segment, the first planar segment having a first portion and a second portion, in which the plurality of holes are positioned in the second portion; and
a second planar segment comprising:
a first layer including a non-conductive substrate,
a second layer including conductive materials comprising at least a first temperature sensor, a second temperature sensor, and a conductor element,
a third layer including an insulator,
a first sector comprising a first portion of the first layer, a first portion of the second layer, and a first portion of the third layer, and
a second sector comprising a second portion of the first layer, a second portion of the second layer, and a second portion of the third layer,
in which the flexible circuit is configured to be formed onto a core of a catheter body, the core having a lateral surface, a base disposed perpendicular to the lateral surface, and a curved surface connecting the lateral surface to the base, such that the second planar segment conforms to the lateral surface and such that the first portion of the first planar segment conforms to the base and the second portion of the first planar segment conforms to the curved surface.
