Over the few years, there have been great steps in the development of functional prosthetic hands. However, even the most advanced hands lack a combination of high functionality and affordability. A new prosthetic hand has been designed and developed combining high functionality and affordability thanks to rapid prototyping techniques. This video presents the design of a five-fingered prosthetic hand that can be programmed to have multiple grip patterns using force myography (FMG) as a control signal instead of electromyography (EMG) signal. A novel FMG sensor was developed using strain gages and a high resolution ADC to detect mechanical muscle contractions from the residual forearm of amputees.
