Over 200,000 upper limb amputees lack access to customizable, functional, and low-cost prostheses. The Million Hands team designed a selection of body-powered and electrically-powered prostheses, all under $500.

An Online Open Source Platform
As a newly formed group in 2017, we set out to assess user needs by observing and interacting with patients and doctors specializing in upper-limb amputation. We defined sustainable goals: creating a library of passive and active hand designs, developing a simple but robust myoelectric prosthetic, and integrating all devices onto an online platform.

OUR PARAMETRIC MODEL ACHIEVES CUSTOM FITTING
Uniform scaling doesn’t really address the problem of different hand sizes. Our parametric model scales part dimensions to closely replicate original hand proportions, lending a natural, comfortable fit for our device.
PASSIVE PROSTHETICS MEET FUNCTION-SPECIFIC NEEDS
Our mission is to create modular, function specific prosthetics. From our monkey-bar hand to our conductive phone-tap finger, we’re designing robust, innovative products that address niche used needs.
MYOELECTRIC MODULE FOR ADVANCED FUNCTION
We’re using EMG sensors to monitor and process muscle activity to control the prosthetic with mere muscle flexion. This also includes a haptic feedback module which allows users to gauge the power of their grasp.
Key Features:
- Non-uniform scaling
- Function specific
- Modular design
- Easy assembly
- Myoelectric
- Flex function
- Haptic feedback
