“…Push actuators named InLastor were fabricated by rolling the DEA membrane in a cylinder of many layers. With 2500V actuation (∼ 31 V/µm), the actuators exhibit a 3% linear strain, a blocking force of 6 N/cm 2 and a response time below 10 ms [59].…”

“…Danfoss Polypower were the first to manufacture in high volume an electrode-coated DEA material. They have developed custom machinery that enable roll-to-roll production of hundreds of meters of DEA membranes, from the corrugated membrane fabrication to the lamination of two films to form a capacitor [59]. The electrodes are deposited by a roll-to-roll vacuum sputtering process, which follows the delamination of the membrane from the mould, whose profile height and period are respectively 4 µm and 10 µm.…”

Flexible and stretchable electrodes for dielectric elastomer actuators

Dielectric elastomer actuators (DEAs) are flexible lightweight actuators that can generate strains of over 100%. They are used in applications ranging from haptic feedback (mm-sized devices), to cm-scale soft robots, to meter-long blimps. DEAs consist of an electrode-elastomer-electrode stack, placed on a frame. Applying a voltage between the electrodes electrostatically compresses the elastomer, which deforms in-plane or out-of plane depending on design. Since the electrodes are bonded to the elastomer, they must reliably sustain repeated very large deformations while remaining conductive, and without significantly adding to the stiffness of the soft elastomer. The electrodes are required for electrostatic actuation, but also enable resistive and capacitive sensing of the strain, leading to self-sensing actuators. This review compares the different technologies used to make compliant electrodes for DEAs in terms of: impact on DEA device performance (speed, efficiency, maximum strain), manufacturability, miniaturization, the integration of self-sensing and selfswitching, and compatibility with low-voltage operation. While graphite and carbon black have been the most widely used technique in research environments, alternative methods are emerging which combine compliance, conduction at over 100% strain with better conductivity and/or ease of patternability, including microfabrication-based approaches for compliant metal thin-films, metal-polymer nano-composites, nanoparticle implantation, and reel-to-reel production of µm-scale patterned thin films on elastomers. Such electrodes are key to miniaturization, low-voltage operation, and widespread commercialization of DEAs.

To our knowledge no known technologies or processes are commercially available for embossing microstructures and sub-micron structures on elastomers like silicones in large scale production of films. The predominantly used technologies to make micro-scale components for micro-fluidic devices and microstructures on PDMS elastomer are 1) reaction injection molding 2) UV lithography and 3) photolithography, which all are time-consuming and not suitable for large scale productions. A hot-embossing process to impart micro-scale corrugations on an addition curing vinyl terminated PDMS (polydimethyl siloxane) film, which is thermosetting elastomer, was established based on the existing and widely applied technology for thermoplasts. We focus on hot-embossing as it is one of the simplest, most costeffective and time saving methods for replicating structures for thermoplasts. Addition curing silicones are shown to possess the ability to capture and retain an imprint made on it 10-15 minutes after the gel-point at room temperature. This property is exploited in the hot-embossing technology.
