A plurality of particles are densely packed as an array on a flexible substrate. As at least a portion of the substrate responds mechanically to an external stimulus, the coated substrate is useful as a sensor device to the extent that the mechanical response produces a separation between particles resulting in a measurable change in the physical properties of the array. Preferably the particles are conductive, spherical and of nano-scale for greater sensitivity. When the array comprises closely packed conductive nano-particles deformation of the substrate disturbs the electrical continuity between the particles resulting in a significant increase in resistivity. The various optical properties of the device may exhibit measurable changes depending on the size and composition of the nano-particles, as well as the means for attaching them to the substrate.
