Claim 13:
14. A friction element that senses an external compression force applied to the friction element, the friction element comprising:
a support element;
a friction material attached to the support element;
a force sensor positioned between the support element and the friction material, the force sensor comprising a top surface , the force sensor configured to output a response signal; and
a protective element positioned between the friction material and the force sensor such that the top surface of the force sensor is separated from the friction material by the protective element,
wherein the protective element comprises resin-based material which protects the force sensor, and
wherein the protective element applies a final force (Fp) to the force sensor in a direction of external compression force (F) applied to the friction material, and the resin-based material is selected such that Fp/F is not less than 0.01.
