3D-Printed Myoelectric Prosthetic Hand’s Design and Development Featuring Velostat Pressure Sensing

Abstract
This paper presents the design and development of a cost-effective myoelectric prosthetic arm featuring Velostat pressure sensing for enhanced functionality and safety. The prosthetic arm, designed specifically for below-elbow amputees, incorporates three motors for finger control and utilises 3D printing technology for fabrication using polylactic acid (PLA). Velostat, a polymeric foil impregnated with carbon black, is strategically placed at the fingertips to enable real-time pressure sensing. The integration of myoelectric sensors captures electromyographic (EMG) signals, which are processed and used to control the prosthetic's movements via a microcontroller. The innovative use of Velostat as a pressure sensing element offers a cost-effective alternative to traditional sensors, enhancing grip force measurement and safety features. The paper details the design methodology, mechanical considerations, sensor integration, hardware implementation, and software processing techniques. Results demonstrate the feasibility and effectiveness of the proposed prosthetic arm, highlighting its potential to address the need for affordable and functional prosthetic solutions, particularly in regions with limited access to healthcare resources.
