“…If the film is incorporated into a compliant frame with appropriate preloading, as shown in Figure 10, the film's orthogonal expansion can be converted into useful mechanical work. Linear strains of approximately 200% are possible with such a design [14]. When compared to conventional DC motor/gearhead combinations, dielectric elastomer actuators contain 10 to 100 times fewer parts.…”

“…Under activation with a high DC voltage (kV ), the electrostatic pressure squeezes the elastomer film in thickness and thus, the incompressible film expands in planar directions. By properly configuring the DE actuator, the three-dimensional deformation of the film can be transferred into axial, 23,24 bending and radial motion. As shown in Fig.…”

Miniature spring roll dielectric elastomer actuators for a novel kinematic-free force feedback concept were manufactured and experimentally characterized. The actuators exhibited a maximum blocking force of 7.2 N and a displacement of 5 mm. The theoretical considerations based on the material's incompressibility were discussed in order to estimate the actuator behavior under blocked-strain activation and free-strain activation. One prototype was built for the demonstration of the proposed force feedback concept.

Dielectric elastomer actuator (DEA) show promise for mechatronic applications due to the advantages of dielectric elastomer, such as lightweight, flexible, low cost, high strain, etc, and many configurations of DEAs have been demonstrated. As a kind of linear actuator, cone DEAs are studied in some laboratory prototypes due to easy manufacturing, however, their performance have not been exploited fully. Based on the working principle of DEA, a four-bar linkage mechanism is designed to provide negative stiffness preload, which can increase displacement output of actuator (outer diameter 100 mm) to 17 mm. Three cone actuating units are assembled in parallel to enhance the maximum force output to 5.07 N. Loading experiments of actuator in forward and backward strokes are performed, the experimental results show that backward stroke has stronger actuating capability than forward stroke, accordingly application of actuator is recommended. Four factors rather than applied voltage, i.e., number of actuating units, pre-stretch ratio, inner diameter, and outer diameter, are determined as influencing factors for Taguchi method. Then the performance objectives of actuator, i.e., displacement output, maximum force output, and maximum work in backward stroke, are investigated based on L 9 (3 4 ) Taguchi orthogonal design. The mean signal-to-noise (S/N) ratio based on the larger-the-better criterion is calculated according to the acquired displacement and force output. Analytical results show that outer diameter has the most significant influence on displacement output, and maximum force out and work output are influenced most by number of actuating units. Inner diameter also has an important effect on the performance objectives of actuator, while pre-stretch ratio has the least influence. The proposed performance investigation is helpful for the design and application of cone actuator in mechatronic system.
