A human interface device is provided, having a substrate. A strain sensitive die is coupled to the substrate wherein the die is capable of providing an electrical signal indicative of a force applied to the strain sensitive die. A force transfer element is positioned adjacent to the strain sensitive die and coupled to the strain sensitive die. A translation element is mechanically coupled to the force transfer element. An elastic element is at least partially surrounding the translation element and the force transfer element, wherein the elastic element provides the mechanical coupling between the translation element and the force transfer element. A force applied to the translation element causes stretching of the elastic element, wherein the stretching of the elastic element causes a force to be applied to the force transfer element; and wherein the force applied to the force transfer element by the elastic element is then applied to the strain sensitive die. |
