A high number of traumas and neurophysiological disorders each year, along with the aging population, has increased the number of people with compromised hand functionality. The need of providing rehabilitative and assistive devices for patients has encouraged the study in hand exoskeletons. Since rigid structures are bulky and may cause fatigue, soft and compliant components have gained attention from the researchers as they can provide better wearability, improve the portability and help in performing more natural movements. The aim of the project is to develop an instrumented testing platform to allow a systematic investigation into the control of a hand exoskeleton made with compliant materials.
