Monodirectional Positioning Using Dielectric Elastomers [PDF]
, 2010 The rationales for the use of microsystems are numerous, including the reduction of consumables, a faster response time, the enhanced portability, the higher resolution, and the higher efficiency; moreover their application sectors are numerous. Nevertheless microproducts have still great difficulty in penetrating the market, mainly due to the limits ...

Dielectric elastomer actuator biased by magnetorheological elastomer with permanent magnet
Smart Materials and Structures, 2023 Abstract Dielectric elastomer actuators have become one of the most important smart material transducers in recent times. One of the crucial aspects in this field is the application of bias to find the best operating conditions. The basic task is to find the proper bias configuration to obtain a wide range of displacements in the ...

A Review of Dielectric Elastomer Generator Systems [PDF]
Advanced Intelligent Systems, 2020 Dielectric elastomer generator systems (DEGSs) are a class of electrostatic soft‐transducers capable of converting oscillating mechanical power from different sources into usable electricity. Over the past years, a diversity of DEGSs has been conceived, integrated, and tested featuring diverse topologies and implementation characteristics tailored on ...

Monolithic Stacked Dielectric Elastomer Actuators [PDF]
Frontiers in Robotics and AI, 2021 Dielectric elastomer actuators (DEAs) are a promising actuator technology for soft robotics. As a configuration of this technology, stacked DEAs afford a muscle-like contraction that is useful to build soft robotic systems. In stacked DEAs, dielectric and electrode layers are alternately stacked. Thus, often a dedicated setup with complicated processes
