The Sensing Skin

The research project aims at developping a large-scale flexible membrane that can be deployed onto monitored surfaces, and behaves like a matrix of capacitance-based strain gauges. The proposed method is analogous to biological skin, in the sense that it is capable of global monitoring by deploying sensors over large regions. Each strain gauge is a soft capacitors, which is fabricated using a highly sensitive elastomer sandwiched between electrodes. Changes in the material geometry correspond to changes in the material capacitance, which are directly related to local deformations.
