Force-Sensing Rehabilitation Glove : A tool to facilitate rehabilitation of reduced hand strength
Abstract: This thesis examines how the pressure sensors can be used in rehabilitation for patients with weakened hand strength. The rehabilitation process usually contains everyday tasks to evaluate the patient’s capability and the tools for this part of the rehabilitation process are few. The challenges will be to find a suitable sensor for the application and how to implement the sensor in a versatile prototype with direct feedback for the user. To solve this problem, research will be conducted on different pressure sensor types to determine the most suitable one for this implementation. The resulting prototype is utilizing a force sensing resistor (FSR) mounted on a glove together with a module that presents direct feedback to the patient and caretaker. The glove has pressure sensors in each fingertip to detect the applied force for each individual finger when the patient grips an object. To present the feedback, a visual interface is created in the form of a hand with a LED for each finger, which provides direct visual feedback and a display to present numerical data.
