A method of producing a printed electronic device on a thin PDMS film which includes coupling a first layer of a water-soluble polymer to a substrate and drying the first layer of the water-soluble polymer. The method further includes coupling a second layer of a crosslinkable PDMS polymer to the first layer of the water-soluble polymer and curing the second layer of the crosslinkable PDMS polymer to form the thin PDMS film. The method also includes printing one or more functional layers on the thin PDMS film and drying the one or more functional layers on the thin PDMS film to form the printed electronic device coupled to the substrate.

Polydimethylsiloxane films and method of manufacture

An impact sensing system includes a first impact sensor having a flexible dielectric layer, a first printed electrode on a first side of the layer, and a second printed electrode on a second side of the layer. The second printed electrode overlies and is moveable toward and away from the first electrode by deformation of the flexible dielectric layer. Further, the layer maintains a capacitance between to the first electrode and the second electrode that changes with a movement of the second electrode toward or away from the first electrode. The system further includes a first readout circuit electronically coupled with the first and second electrodes to measure a change in the capacitance and output a corresponding voltage.
