A woman living in Britain created a 3D printed thumb
The designer Dani Clode developed an interesting device called The Third Thumb. It is a prosthesis which doesn’t replace missing limbs but adds new ones.
More precisely, The Third Thumb gives a user an additional thumb. You don’t need to undergo any surgeries. Just put a couple of devices on your hand and, as weird as it may sound, on your foot too.
A microcontroller with pressure sensors is placed on the foot. It communicates with the thumb via Bluetooth connection designed as a bracelet.
The thumb can bend and unbend just like the real one allowing a user to perform various actions. The additional limb improves a human grip and the ability to deal with various objects. Every component of the device is 3D printed.
