Soft gripper inlays or pads are essential for turning low grip forces into large lift forces with a prosthetic gripper. The Toughware Equilux has exchangable gripper pads and lends itself to modification. As heavy user of these devices I play with the setup to improve it. This is my latest innovation - self made silicone rubber pads with great grip forces.
