Dani Clode is a graduate student at London’s Royal College of Art (RCA) along with her most recent creation is something known as the Third Thumb: a 3D-printed prosthetic that does precisely what its name suggests. “The source of the phrase ‘prosthesis’ supposed ‘to include, put to,’ so not to replace or fix, but to extend,” Clode told Dezeen. “The Third Thumb is inspired by this word origin, researching human enhancement and aiming to reframe prosthetics as extensions of their human body”
The thumb straps to both sides of the hands, and joins into a bracelet containing cables and servos. The wearer controls it with pressure sensors that sit beneath the bottoms of the feet. Should they press down with a single foot the thumb will probably create a grasping motion, with these directions delivered to the wrist device via Bluetooth. It seems a bit neater, but Clode says folks pick this up pretty fast. It is no more complicated than, say, steering a vehicle and operating the brake and accelerator at precisely the exact same moment.
