A unimorph nanocomposite dielectric elastomer for large out-of-plane actuation

Junhong Pu et al.

Summary: This study introduces an electrophoretic process to concentrate boron nitride nanosheets onto a designated electrode surface, forming a seamless bilayer structure with significant modulus difference, called the unimorph nanocomposite dielectric elastomer (UNDE). This material shows improved performance in terms of breakdown field strength and durability compared to conventional nanocomposite dielectric elastomers. Multiple UNDE units can be formed using a simple electrophoretic concentration process, and they can be used to create high-stroke actuators. The experimental disc-shaped actuator demonstrated the capability of a high-speed lens motor to vary the focal length of a two-lens system by 40 times.

Summary: Dielectric elastomers (DEs) are capable of generating mechanical work in response to an electric field. In this study, a processable, high-performance dielectric elastomer (PHDE) with a bimodal network structure was synthesized, and its electromechanical properties were tailored by adjusting cross-linkers and hydrogen bonding. The PHDE exhibited high strains without prestretching and multilayer actuators were fabricated using a dry stacking process.

Jonas Hubertus et al.

Summary: This paper presents an electromechanical characterization of thin film nickel-based wrinkled electrodes for dielectric elastomer (DE) applications. Compared to conventional screen-printed carbon black electrodes, nickel-based thin film electrodes offer a significantly lower ohmic resistance. The ultrathin layers are deposited onto prestretched silicone membranes, resulting in wrinkled out-of-plane buckled surfaces and demonstrating strong adhesion to the silicone, allowing for strains up to 200% while remaining conductive.
