That’s where the Third Thumb came in. The Third Thumb is a flexible 3D-printed thumb extension that is controlled wirelessly via two pressure-sensitive sensors attached to the big toes. It was created by the designer Dani Clode and now used by scientists at the UCL to find out how body augmentation is perceived by the human brain. Researchers tested the Third Thumb over a period of five days in which participants in the study learn to use the appendage for various tasks involving grabbing objects, holding a mug, and more complex activities as well. They all managed to master using the thumb very quickly and, most importantly, started to experiment a sense of embodiment, meaning the thumb started to feel like a natural part of their body.
