Description
Summary:Myoelectric prosthesis on the market today are mostly very expensive and rarely allow the amputee any feedback, leaving the users separated from their own robotic arm. Integrating sensory systems into an arm which needs to be replaced several times during a lifetime may also not be cost efficient. With a sensory system tted in a removable and re-sizeable glove, the sensory system will not require a replacement unless broken. Using a exible, durable, low-cost material, sensitive to both change in pressure and temperature, this may be achieved. Using the pyroelectric properties of thin-film Polyvinylidene Fluoride, a sensor able to detect the incipient of slippage and its initial direction is achieved.
