Smart Phone Controlled 3D Printed Hand Prosthetic Using Bluetooth Technology

This research article details the development of a Bluetooth-controlled 3D printed hand prosthetic using MIT App Inventor and polylactic acid (PLA) material through fused filament fabrication (FFF) technology. The aim of the study was to create a functional prosthetic hand that could be wirelessly controlled using a smartphone application while keeping the cost low. Motion was achieved through servo motors controlled by a microcontroller via Bluetooth, with voice commands and sliders available on the smartphone app. The use of FFF technology allowed for greater customization, cost-effectiveness, and accessibility in the design and fabrication of the prosthetic hand, including the ability to customize the size, shape, and functionality. The study concludes with an evaluation of the final product, highlighting its success in meeting the study's objectives and discussing its potential for use in prosthetics research and development.
