How many times have you wished for a third hand while trying to carry too many things? Well, you can’t have that yet because it’s not a thing (at least not an available thing), but maybe you can get yourself another thumb, which is almost as good. Dani Clode, a graduate student at the Royal College of Art in London, created The Third Thumb, a 3D-printed prosthetic that straps onto your hand.
The thumb is motorized and connected by cables to a bracelet. Pressure sensors underneath the wearer’s feet connect to the thumb’s motors via bluetooth. So, working the extra digit just requires you to press down with your foot. Clode said that she linked the thumb to foot controls because with actions like driving, using a sewing machine or playing piano, we already have practice completing tasks that require hands and feet to work together.
