Myoelectric prosthetic 3D printing hand

The myoelectric hand, known has Handiii, transmits EMG sensor information from the arm to a smartphone using a wireless communication link embedded under the prosthesis. The smartphone algorithms interprets these signals to control the arm. The invention allows the wearer to toggle through a range of programmable grips such as a pinch grip, five fingered grasps etc. via a small button on the elbow.

Handiii is a quality bionic prosthetic that costs about $300. The Handiii Myoelectric hand cuts costs by incorporating app-based smartphone technology that collects signals from the muscles of the amputated arm. This data is then wirelessly sent to the myoelectric arm. However, much more money is saved by the clever design of the arm itself, which is constructed from 3D printed parts – for easy repair and customization – and features just a single motor per finger.

The invention was been developed since 2013, and the first prototype was launched in 2015.

By the end of 2014, the team launched a crowdfunding campaing to raise money to build the first working Handiii’s for two coworkers. They gathered $29,000 and are using the funds to try to create arms to people who need them.
The team is also working to try to make Handiii open source and available for technical universities.
