Trends in EMG based Prosthetic Hand Development: A Review
نویسندگان
چکیده
In this paper we have discussed the trends undergoing in all the various steps involved in EMG (Electromyogram) based prosthetic hand development. In order to overcome some limitations of current prosthetic hands mainly related to the proper functionality and controllability, the prosthetic hand has been designed following a biomechatronic approach based on biologically inspired design solutions. The majority of electrically powered prosthetic hands are based on a simple design that limits motion to one degree of freedom. Designs of multi-articulated prosthetic hands have had limited success due to their complexity and number of mechanical components. Classical EMG (myoelectric) controllers have failed in the past, since they were based on only determining existence or nonexistence of an EMG signal. Recent work has approached this multifunctional control problem using a large number of electrodes, though still considering only a limited part of the EMG spectrum.

Biomimetic Impedance Control of an EMG-Based Robotic Hand
The number of extremity amputations resulting from workplace mishaps, traffic accidents and other incidents has shown an increasing trend over time, although the importance of safety management and the prevention of such accidents is fully recognized. Since precise and complex motion may be very difficult in the daily activities of amputees, the development of prosthetic systems is necessary to...
متن کاملBrain activation during manipulation of the myoelectric prosthetic hand: a functional magnetic resonance imaging study.
Neuroimaging data, particularly functional magnetic resonance imaging (fMRI) findings, have not been reported in users of the myoelectric or electromyographic (EMG) prosthetic hand. We developed a virtual EMG prosthetic hand system to eliminate mutual signal noise interference between fMRI imaging and the EMG prosthesis. We used fMRI to localize activation in the human brain during manipulation...

In this paper some recent results about the experimental trials we are performing on a functional prosthetic hand characterized by an EMG-control and by a simple and low cost fabrication technology are shown. A compliant under-actuated prosthetic hand has been designed and fabricated. The five-fingered hand (both palm and fingers) is moulded as a soft polymeric single part with compliant joints...
متن کاملAnalysis of Grasping Motion Using a Virtual Prosthetic Control System
Electromyogram (EMG) signals can be measured from human muscles and can be used to anticipate movements. In fact, many researchers have tried to use these signals as an interface tool for a prosthetic hand. However, most of these studies focused on the discrimination performance of the EMG signals, and only discussed the control method for the prosthetic hand. Evaluation of the operating perfor...
