Esp32 based wearable wrist device for monitoring and managing risks in patients with congenital insensitivity to pain with anhidrosis (cipa sense-band)

Abstract

People with Congenital Insensitivity to Pain with Anhidrosis (CIPA) face dangerous health conditions because they cannot feel pain and they cannot feel when their body temperature reaches dangerous levels. The study aims to develop and evaluate a wrist device called the CIPA Sense-Band which functions as a continuous monitoring system for risk assessment. The system uses an ESP32 microcontroller together with body temperature and heart rate and movement and pressure sensors to detect hazardous conditions. The system immediately activates vibration alerts together with caregiver text messages whenever it detects abnormal readings to enable rapid response. We tested the device in controlled and simulated settings to see how accurate, responsive, and comfortable it was. The overall accuracy of injury detection was 86.7%, and the accuracy of impact detection was 96.7%. Heart rate monitoring achieved 92.5% accuracy when compared to a medical reference device while most users reported they could comfortably wear it throughout the day. The CIPA Sense-Band functions effectively as an early risk detection tool which helps caregivers to improve their monitoring of potential threats. The research shows that an affordable wearable device exists which can improve safety for people with CIPA, but researchers need to enhance temperature sensing and conduct field trials.
