Dielectrophoretic Elastomer Actuators for Soft Pneumatic Pumps

Dielectrophoretic elastomers actuators are a new class of actuator capable of achieving out-of-plane deformation by the stimulation of external electric fields, providing an alternative approach for soft electric actuators. Pneumatic pumps based on dielectrophoretic elastomer actuators have been presented with a simple structure, facile fabrication, and low cost. Here, we demonstrate an improved version of pneumatic pump with a stand-alone soft materials structure and optimized air chamber design. The component configuration, actuation mechanism, and working performance are investigated, which reveals the enhanced output and durability. By using flexible building blocks, the pump can be bent and twisted, representing a step forward in the use of dielectrophoretic elastomers in soft robotic applications.
