Electrohydraulic Actuator

Electrohydraulic actuators, particularly Hydraulically Amplified Self-Healing Electrostatic (HASEL) actuators, are artificial muscles offering high power density and speed, mimicking biological muscle function. Current research focuses on improving their controllability, including developing self-sensing capabilities to eliminate the need for external sensors and employing series elastic components or AC driving to achieve smoother, more stable displacement. These advancements are enabling the creation of more sophisticated biomimetic robots, prosthetics, and wearable devices with improved dexterity, compliance, and safety, particularly in applications requiring complex movements and interactions with unstructured environments.
