A sensing device includes a first layer, a second layer, and an optical sensor. The first layer includes a first surface for supporting an associated load. The first layer transmits a strain to a second surface due to the associated load located on the first surface. The second layer is formed of a compliant material and provides substantially uniform support to the first layer and deflects due to the associated load. The optical sensor is positioned between the first and second layers and senses the strain due to the associated load.
