DEVELOPMENT HAND REHABILITATION DEVICE USING IOT
Main Article Content
Abstract
This project presents the development of a wearable IoT-based hand rehabilitation device aimed at assisting individuals suffering from nerve or tendon weakness. The system is designed to automate hand exercises by enabling controlled opening and closing of fingers at specific speeds, time and the selected the number of specific fingers. It is powered by an ESP32 microcontroller and controlled via the Blynk mobile application or manually using potentiometers to set speeds and time. The device utilizes an air pump, vacuum pump, and seven solenoid valves to manage pneumatic movement for each finger independently. An I2C LCD is used to display current settings, fingers, speed levels and time. All components are securely mounted inside a laser-cut acrylic box, offering portability and safety. This solution provides a cost-effective and customizable alternative to conventional rehabilitation methods, enhancing recovery through consistent and precise training routines.
