In effort to Three dimensionally Fabricate Finger Prosthesis Using Hybrid Materials with Integrated Tactile Sensing

This study presents a novel approach to fabricate a finger prosthesis utilizing hybrid materials and 3D printing techniques. The fabrication process integrates both extrusion and Stereolithography (SLA) printing techniques, employing Polylactic Acid (PLA) and bio-resin to construct the scaffold structure. Additionally, a tactile sensing scaffold will be fabricated on the fingertip using Polydimethylsiloxane (PDMS) releasing through a pneumatical extrusion-based 3D bioprinter. This hybrid-material approach combines the mechanical strength of PLA, dimensional accuracy, and biocompatibility of bio resin, enhancing the prosthesis's structural integrity and user comfort. The integration of PDMS for tactile sensing offers a crucial advancement in providing a naturalistic haptic experience for prosthesis users. This research represents a significant step forward in the development of functional and sensory-enhanced finger prostheses, demonstrating the potential for personalized, high-performance solutions in the field of prosthetic technology.
