Grabbing the new iPhone has been too mainstream but grabbing it with your prosthetic thumb is different. Prosthesis (as ancient the Greeks or geeks call it), or adding a third thumb in your finger set via prosthetic thumb technology, is now at your thumbnail. The third thumb is designed by Danielle Clode a grad student in Royal College of Art. This prosthetic thumb can be a part of your tool or experience moreover your self-expression or emotion.
Three parts of the Third Thumb
The third Thumb is made of three parts produced by a multi-shore 3D printer in the rigid, smooth from labs gray resin.
The main part, the thumb is live-hinge based design, 3D printed out of the tough, 85a shore flexible filament, Ninjaflex.
The middle part is the bracelet to strap on wrist inspired visually by a cross between a watch, a power tool, and a fitness tracker.
The third part of the third thumb is the foot control embedded with pressure sensors retrofitted under your shoe at toe position and paired with Bluetooth.
Your thumb doesn’t follow other fingers it roams free from the tension among other fingers making it more functional than a single finger. The third thumb replicates the opposite directional movements by using two motors a Bowden cable system, similar to a bike brake, made of Teflon tubing and wire pulling against the natural tension of a flexible 3D printed material. The two motors controlled by two pressure sensors fitted under shoe transmit the senses via Bluetooth alike neurotransmitter in the biological body part.
Replacing an organ with a prototype was in practice since the ancient Greek but adding Prosthesis of an organ into the perfect creation can extend the possibilities. The third prosthetic thumb is still a demonstration of the future holding the idea to add a new branch to the tree instead of fixing it.
