Desarrollo de un guante vestible que permita el control a distancia de una prótesis de mano personalizada utilizando sensores de flexión y presión

Abstract

This project developed a wearable glove capable of remotely controlling a customized hand prosthesis using flex and pressure sensors. The device detects finger movements and transmits them to a wireless control system, enabling precise real-time manipulation of the prosthetic hand. The glove integrates flexible and force sensors, an Arduino Nano as the controller, Bluetooth HC-06 communication, and MG90S servomotors that execute the prosthetic movements. The mechanical design of both the prosthesis and glove was created using CAD software, with 3D printing in PETG filament and resin to ensure ergonomics and durability. The electronics were implemented with printed circuit boards and components such as voltage regulators, LM324N ICs, and capacitors, providing a stable and reliable system. Programming on the Arduino included sensor filtering and calibration to optimize reading accuracy and prosthesis control. The prototype was evaluated through flexibility tests, grip trials, and force analysis, focusing on representative pinching and palmar movements. Results demonstrated intuitive, smooth, and safe control, significantly enhancing user autonomy and quality of life. This development offers an innovative and accessible solution for individuals with amputations, integrating remote control, sensory feedback, and personalization according to each user’s needs.
