| Summary: | Executing daily chores with missing limbs is
undoubtedly very challenging. For a person who has lost
his lower arm, it is highly desirable to replace this loss
with a device that not only identical in appearance, but
closely mimics its capabilities. While there are many
prosthetic products of multiple functionalities in the
current market, the capability of the device to replicate the
tactile sensory system are often neglected.
This research looks into supplementing a vibrotactile
sensory feedback to the residual arm of prosthetic hand
users. Surface information obtained at the fingertip of the
prosthetic device becomes the input signals to the haptic
actuator in generating vibration output. An Eccentric
Rotation Mass (ERM) miniature motor has proven its
capability to produce the required vibration in 2-axis
direction within frequency bandwidth that matches the
mechanoreceptor of the human skin. These findings are a
stepping-stone in creating a real tactile sensation for
prosthetic users. |
