Latest Patents

One of Clarke's latest patents involves manufacturing techniques and devices using dielectric elastomers. This invention includes a dielectric elastomer device that consists of first and second dielectric elastomer layers, with a layer of conductive particles forming a first electrode. The design allows for portions of the second dielectric elastomer layer to be directly bonded with the first layer through the conductive particles. The dielectric elastomer layer may comprise a cured acrylic elastomer precursor with additives such as urethane, polybutadiene, or silicone. Additionally, electrodes in different layers can be interconnected by infusing a liquid or semi-liquid conductive material, which solidifies to create a conductive path.

Another significant patent by Clarke is for tunable blinds for windows. This invention features methods and apparatus for modulating light using a tunable light modulation device. The device includes an elastomer structure with a compliant electrode network of conducting fibers and a patterned electric conductor. The individually-addressable sections of the patterned electric conductor allow for voltage-dependent roughening of the elastomer layer, enabling effective light modulation.
