When using prostheses and exoskeletons, there is always a possibility of discomfort due to pressure points between the limb and the material. This discomfort can lead to serious medical issues for the user, such as skin irritation and wounds. It is important to be able to determine the magnitude and location of the pressure on the limb to limit the consequences for the patient.
To properly determine the influences on the limb the inter-action force will be expressed in friction(shear force) and pressure(normal force). As the pressure and friction points differ for each patient a production method for the sensor is necessary that can be adapted to each situation. This led to the decision of using 3D printing techniques to create more freedom in the adaptability of the design.
In this research, we look into what steps need to be taken to develop a flexible 3D-printed capacitive shear sensor for application in interaction force measurements. Next to that, it is tried to determine what the challenges will be of 3D printing a flexible capacitive shear sensor for application in interaction force measurements.
