Abstract:
1. A flexure sensing device comprising: a substrate having a flexible portion and a non-flexible portion; a first electrically resistive element formed on or within the flexible portion of the substrate, the first electrically resistive element having a variable electrical resistance dependent on a change in flexure of the flexible portion of the substrate; and a second electrically resistive element formed on or within the non-flexible portion of the substrate, the second electrically resistive element providing a reference resistance for biasing the flexure sensing device such that the reference resistance provides a fixed resistive element of a bias network; and a common conductor coupled between the first electrically resistive element and the second electrically resistive element, the common conductor formed on or within both the flexible portion of the substrate and on or within the non-flexible portion of the substrate; a first terminal connected to the first electrically resistive element, a second terminal connected to the second electrically resistive element, and a third terminal connected to the common conductor, the first terminal, second terminal, and third terminal being configured to be electrically coupled to contacts in a printed circuit board (PCB); wherein the non-flexible portion of the substrate surrounds at least a portion of the flexible portion of the substrate.
