Abstract
Official abstract text for this publication.
According to the present disclosure, a strain gauge includes: a flexible substrate; a resistor made from a film containing Cr, CrN, and Cr2N, on one surface of the substrate; an insulating layer covering the resistor; and a conductive barrier layer covering the insulating layer.
First claim
Opening claim text (preview).
1 . A strain gauge comprising: a flexible substrate; a resistor made from a film containing Cr, CrN, and Cr 2 N, on one surface of the substrate; an insulating layer covering the resistor; and a conductive barrier layer covering the insulating layer. 2 . The strain gauge according to claim 1 , wherein the insulating layer is made from an organic material. 3 . The strain gauge according to claim 1 , wherein the barrier layer is made from a metal, an alloy, or a laminated film in which metals, alloys or both are laminated. 4 . The strain gauge according to claim 1 , wherein the barrier layer covers an upper surface and side surfaces of the resistor, in a continuous manner, via the insulating layer. 5 . The strain gauge according to claim 1 , further comprising a conductive layer formed on the other surface of the substrate. 6 . The strain gauge according to claim 1 , wherein a gauge factor is 10 or more. 7 . The strain gauge according to claim 1 , wherein the CrN and the Cr 2 N contained in the resistor are 20% by weight or less. 8 . The strain gauge according to claim 7 , wherein a proportion of the Cr 2 N in the CrN and the Cr 2 N is 80% or more by weight and less than 90% by weight.
