Abstract
A sensor assembly includes a flexible substrate with conductive traces formed on opposed sides of the substrate and oriented transversely to each other. The substrate is wrapped around a core so that the traces formed on opposed sides of a first part of the substrate form a first sensor surface on one surface of the core, and the traces formed on opposed sides of a second part of the substrate form a second sensor surface on an opposed surface of the core. The core may comprise an encapsulant overmolded onto the conductive traces on a surface of the first part of the substrate, and the second part of the substrate is folded over the encapsulant. The sensor assembly may include an integrated circuit disposed on the flexible substrate, wherein one or more of the conductive traces are electrically connected to each integrated circuit.
