The Third Thumb, a 3D-printed thumb that is attached to the hand and controlled with the feet, is the brain child of designer Dani Clode. His goal is to challenge the perception of prosthetics, making them as socially accepted as glasses or even plastic surgery.
The human thumb has a really dynamic movement, the opposing movements working together make the thumb more functional than a single finger. The Third Thumb replicates these movements by using two motors pulling against the natural tension of a flexible 3d printed material. The motors are controlled by two pressure sensors retrofitted into your shoes, under your toes, and communicate to the thumb via Bluetooth connection. The foot control is inspired by products that help to develop the already strong connection between our hands and our feet. For example driving a car, using a sewing machine, or playing a piano.
