My name is Gerwin Smit, and I’m an Associate Professor at the BioMechanical Engineering (BME) department.

My research focuses on design of innovative assistive technology that is accessible to all, by using the newest technologies. Examples of assistive technologies are prostheses and orthoses. These devices should be comfortable to be worn, and they should be intuitively controllable by the prosthesis user, with little effort.

The ‘Hundred Dollar Hand’ or iGrip

We have developed the Hundred Dollar Hand. An affordable prosthetic hand, that can be 3D-printed anywhere in the world. This prosthetic is now available on the market as the iGrip prosthetic hand. It is being produced by Vispala, in Kolkata, India. Is has already been supplied to many people in India and Africa. See below a video on the Hundred Dollar Hand.

The Self Grasping Hand, or mHand Adapt

We also developed the Self Grasping prosthetic hand. This prosthetic hand is inspired by the principle of the human hand anatomy, called ‘tenodesis’. The hand closes when the wrist is flexed backwards. This patented mechanism, allows the user to grasp objects, without motors and batteries, and without the need of using the healthy hand. The Self Grasping hand, has been brought to the market as the ‘mHand Adapt’ by MoveAble, Ede, Netherlands. See below a demonstration of the hand in daily practice.

The CloudWalker

We are currently working on the development of a lightweight affordable exoskeleton, the CloudWalker.

Project Inspiration
During the early days of the COVID crisis, we developed a mechanical ventilator, that could be quickly produced anywhere in the world. If you want to know more about Project Inspiration, have a look at this page: https://www.bitegroup.nl/research-projects/project-inspiration
