the german company handprothese specializes in prosthetics with ultra realistic fluid motion. their robotic
hand prosthesis attaches to the users body, linking their hand with their arm muscles. when the user
contracts their muscles to move their hand a sensor picks up a signal to make the hand move accordingly.
the hand’s movement is made ultra realistic thanks to miniature flexible fluid actuators to create the
organic movements and a cosmetic cover that makes it look like a real hand. in addition to being realistic,
this technology makes the device light, compact and inexpensive. the hand also allows adaptive grasping
to hold things securely and each finger can move its position.
