Sheima, Yauhen published the artcileArtificial Muscles: Dielectric Elastomers Responsive to Low Voltages, Product Details of C17H28O8S4, the main research area is dielec elastomer permittivity thin film actuator artificial muscle; dielectric elastomer actuators; high permittivity elastomers; high permittivity polysiloxanes; thin films; thiol-ene addition.
The lack of soft high-dielec.-permittivity elastomers responsive to a low voltage was a long-standing obstacle for the industrialization of dielec. elastomer actuators (DEA) technol. Here, elastomers that not only possess a high dielec. permittivity of 18 and good elastic and insulating properties but are also processable in very thin films by conventional techniques are reported. Addnl., the elastic modulus can be easily tuned. A soft elastomer with a storage modulus of E = 350 kPa, a tan δ = 0.007 at 0.05 Hz, and a lateral actuation strain of 13% at 13 V μm-1 is prepared A stable lateral actuation over 50,000 cycles at 10 Hz is demonstrated. A stiffer elastomer with an E = 790 kPa, a tan δ = 0.0018 at 0.05 Hz, a large out-of-plane actuation at 41 V μm-1, and breakdown fields of almost 100 V μm-1 is also developed. Such breakdown fields are the highest ever reported for a high-permittivity elastomer. Addnl., actuators operable at a voltage ≥200 V are also demonstrated. Because the materials used are cheap and easily available, and the chem. reactions leading to them allow upscaling, they have the potential to advance the DEA technol.
