Bionic hands are electromechanical devices that are able to attach to the body. Their goal is to match the functionality of a human hand.
Bionic hands have a high functional demand. The loss of a hand can be devastating, and can result in individuals having significant limitations throughout their everyday lives. The primary causes for a loss of a hand is trauma, dysvascularity (insufficient blood supply), or neoplasia (excess cell growth/tumors). Bionic hands are especially necessary because transplant surgery is both inefficient and unrealistic for the majority of amputee patients.
There are a wide variety of different styles, sizes, and components of bionic hands to meet the different needs of amputees. Bionic hands vary based on level of amputation, price point, and functionality. For example, three different configurations are shown below, each catering to a different level of amputation.
There are also variations based on level of articulation, manufacturing method (i.e. 3D-printed or not) or desired level of camouflage.
