According to the abstract released by the Intellectual Property India: "The integration of additive manufacturing technologies with advanced sensing capabilities has revolutionized the field of prosthetics, offering new avenues for enhancing user experience and functionality. This research explores the development and evaluation of an additive manufactured prosthetic arm integrated with a Myoware muscle sensor, aimed at improving comfort, durability, and cost-effectiveness compared to conventional prosthetic arms. The methodological approach involves capturing muscle signals using a Myoware muscle sensor, which detects electrical activity generated by the user's muscles. These signals are then processed by an Arduino Nano microcontroller, facilitating real-time analysis and interpretation. Processed signals subsequently drive servo motors integrated into the prosthetic arm, enabling precise movement and gripping actions synchronized with muscle signals for intuitive object manipulation. Results indicate significant improvements in comfort, durability, and cost-effectiveness compared to traditional prosthetic arms. Users reported enhanced comfort during prolonged wear, attributed to the customized fit and lightweight design enabled by additive manufacturing techniques. The prosthetic arm demonstrated superior durability, withstanding everyday wear and tear with minimal degradation. Furthermore, the cost-effective integration of the Myoware muscle sensor and additive manufacturing technologies makes the prosthetic arm accessible to a wider range of users, addressing affordability barriers associated with conventional prosthetic solutions. The implications of this research extend beyond the immediate benefits observed in comfort, durability, and cost-effectiveness. The successful integration of advanced sensing capabilities with additive manufacturing techniques opens up new possibilities for personalized and adaptive prosthetic solutions. Future research directions may focus on further optimizing sensor integration, enhancing prosthetic functionality, and exploring innovative materials and manufacturing processes to continue advancing the field of prosthetics. This research contributes to the ongoing efforts to improve the quality of life for individuals with limb differences through innovative and accessible prosthetic solutions."
