Smart Prosthetics: A Systematic Review of 3D-Printed Myoelectric Limbs with Integrated Sensory Feedback

Abstract

The advancement of prosthetic technology has undergone a significant transformation with the incorporation of 3D printing, myoelectric control, and integrated sensory feedback systems. This systematic study analyses the contemporary field of smart prosthetics, emphasizing 3D-printed upper-limb prosthesis augmented with myoelectric data acquisition and tactile feedback systems. The paper examines advancements in materials and fabrication methods, namely the application of biocompatible polymers and soft robotics, alongside control schemes that encompass signal processing and actuation. It also assesses sensor integration, such as touch and pressure sensors, and the consequent enhancements in clinical and functional outcomes, including dexterity, user comfort, and cost-effectiveness. Significant limitations, including power supply issues and user adaptability, are thoroughly examined, with recommendations for enhancing usability and accessibility presented. This analysis underscores the transdisciplinary advancements influencing next-generation prosthetics and stresses the necessity for scalable, user-centric solutions to improve limb replacement technologies.
