Assistive Band for Patients

Abstract

A small wearable assistive technology for patients with speech or physical disabilities is presented in this paper. Through embedded sensors, the system records wrist motions and converts them into real-time, personalized messages that are shown on a mobile application. The device, which was designed with the Seeed Studio XIAO nRF52840 microcontroller and MPU9250, combines wireless communication, Firebase- based storage, and gesture recognition. The goal of the solution is to facilitate proactive health monitoring and enhance communication between patients and caregivers. Its accuracy, effectiveness, and usability in hospital settings are confirmed by real-world testing.
