Abstract

Low-pressure fluid actuators play a crucial role in various engineering systems, particularly in assisting patients with limited mobility by offering advantages such as energy efficiency and precise control. These actuators are integral to the functioning of self-contained wearable devices, where they provide the necessary force and movement with minimal power consumption. The study delves into the fundamental principles underlying the operation of these actuators, highlighting key considerations in their design process, including material selection, structural integrity, and fluid dynamics. The artificial muscle system comprises three fundamental components: a compressible solid skeletal structure, a flexible fluid-tight skin, and a fluid medium. In this system, the skin is sealed as a bag covering the internal components, ensuring that the fluid remains contained and can exert the necessary pressure to facilitate movement. This paper discusses the experimental setup used to evaluate the performance of a specific component of low-pressure fluid actuators. Key parameters measured include zigzag width, gap size, and duralar distance, all of which are critical in determining the actuator's efficiency and responsiveness. Understanding the intricacies of these parameters allows researchers and engineers to develop more effective and reliable actuators. This has broad applications, from medical devices to robotics, ultimately advancing technology and improving the quality of life for users.
