Brooklyn, New York industrial designer William Root is using 3D scanning, modeling, and printing to create customized prosthetic limbs. Currently, he is working on the prototype for what he calls the “Exo-Prosthetic Leg.”
Each year in the US around 185,000 amputations are performed, 90% of which involve the loss of lower extremities. There are approximately 2 million amputees in the country. The financial, physical, and psychological effects of such a procedure can and often do cause additional trauma to patients, as does adapting to an awkward and sometimes ill-fitting new limb.
Transparent films containing carbon nanobuds—molecular tubes of carbon with ball-like appendages—could turn just about any surface, regardless of its shape, into a touch sensor.
The films were developed by a Finnish startup, Canatu, and could be used to add touch controls to curved automobile consoles and dashboards, for example. The films are rugged and can be repeatedly bent around something as thin as the cord for your earbuds, so they could be handy for adding buttons to flexible devices.
