Development of a Dynamic Fixing System for Wearable Robotics

The development of wearable robotics for rehabilitation and assistive purposes has shown great promise in improving the quality of life for individuals with mobility impairments. However, a major challenge in the design of such devices is the issue of discomfort and pain due to high pressure exerted on the user’s upper limb, particularly during extended use. This study presents the development of a dynamic fixing system aimed at addressing the problem of pressure-induced pain in wearable robotics. The proposed system utilizes adaptive mechanisms that adjust the pressure across the upper limb. By dynamically regulating the fixation force, the system reduces localized pressure points, enhancing user comfort without compromising stability or functionality. The design incorporates soft robotics principles, flexible materials and an actuation system based on innovative actuators to ensure a dynamic pressure distribution and a high level of ergonomy of the fixing system of the robotic device. Preliminary results indicate the effectiveness of the dynamic fixing system in improving comfort and wearability paving the way for more comfortable, long-term use of wearable robotic devices, and contributing to their broader adoption in clinical and everyday settings.
