3D-Printed Myoelectric Prosthetic Hand’sDesign 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.
