Abstract
A propulsion system includes a component and a multi-layer sensing device mounted to the component. The multi-layer sensing device includes a first substrate layer, a first adhesive layer securing the first substrate layer to the component, and a second substrate layer arranged in a stacked configuration with the first substrate layer. The second substrate layer is spaced apart from the first substrate layer by a gap. The multi-layer sensing device further includes a second adhesive layer arranged between the first and second substrate layers to maintain the gap. Thus, the multi-layer sensing device provides passive compensation of viscoelastic creep of the multi-layer sensing device.
