Ian Davis

Ian Davis is a YouTuber and a mechanical engineer known for uploading technology and mechanic videos, especially for his partial hand prosthetic.
== Content ==
His channel is dedicated to engineering a wide variety of things, and most notably, partial hand prosthetic devices that he built for his partially amputated hand.
== History ==
Before YouTube, in early 2019, Ian Davis lost 4 of his fingers on his left hand to an accident that happened at his workplace. His insurance did not cover his prosthetic. Moreover, before that, he was also diagnosed with Multiple Myeloma, an aggressive type of cancer.https://interestingengineering.com/not-satisfied-with-digital-prosthetics-man-invents-own-mechanical-one
Instead of trying to cover his medical expenses, he decided to utilize his professional knowledge as a mechanical engineer and got into 3D printing to build his own prosthetics. He made and scrapped many models of his partial hand prosthetic, but eventually, he showed it on YouTube and announced that there are still improvements and tweaks to add for it.
== Prosthetic ==
Ian's self-made mechanical prosthetic was built as a creative way to cover his medical expenses. Opening or closing the hand only requires 200 milliseconds. Moreover, it doesn't have a battery and it can't get wet. His prosthetic includes a "splay" function.
The prosthetic Ian built has requires zero electricity and it was built with a set of elastic strings, rods, chains, nails and a forearm rest. While the invention functions in its purely mechanical form, Ian also plans to implement an Arduino with a display to gain individual control of the fingers and some servo motors to advance the design.
