Smart Medical Wristband Enables Intelligent Outbreak Prevention in Taiwan

Introduction

Preventing outbreaks and epidemics of highly communicable diseases—such as dengue fever, influenza, or even the Zika virus—has become a global health concern and public policy priority. In partnership with the municipal government, well-known university, and university hospital, AMobile developed a smart medical wristband that leveraged the power of artificial intelligence (AI) technology to help prevent future outbreaks from becoming epidemics in Taiwan.

Project Requirements

Epidemics can arise seemingly from nowhere and spread across national boundaries at alarming speed in today’s highly interconnected world. Consequently, early detection, warning, observation, and treatment are key factors to the success of any outbreak prevention campaign. Frontline medical professionals, health department officials and staff, and the public must all work together to keep an outbreak from spreading.

Since changes in patient vitals, such as abnormal increases in body temperature or heart rate, can indicate the early stages of infection, wearable technology offered a promising solution for around-the-clock patient monitoring. The challenge was developing a solution that can quickly and accurately detect abnormalities in patient health, analyze individual patient medical information with collated environmental data on disease vectors, and dispatch timely warnings to patients, medical professionals, and the public.

AMobile's Solution

Preventing outbreaks and epidemics of highly communicable diseases—such as dengue fever, influenza, or even the Zika virus—has become a global health concern and public policy priority. In partnership with the municipal government, well-known university, and university hospital, AMobile developed a smart medical wristband that leveraged the power of artificial intelligence (AI) technology to help prevent future outbreaks from becoming epidemics in Taiwan.

Project Requirements

The smart medical wristband developed by AMobile not only pushes the boundaries of wearable technology, but also makes outbreak prevention smarter. Until now, the body temperature measurement accuracy of wearable devices was only +/-1°C, which left a wide range for false positives. The new AMobile smart medical wristband effectively increased the accuracy of body temperature monitoring to a range of only +/-0.1°C. By leveraging the MediaTek IoT platform to integrate a mobile chipset into the wristband, the AMobile smart medical wristband is able to transmit real-time information about the patient’s health to a paired mobile phone and regional outbreak prevention system.

When a doctor prescribes the smart medical wristband to help monitor a patient during a period of observation, the patient conveniently purchases and picks up the wristband from the on-site pharmacy. Volunteers or nurses can then immediately help the patient to install the app onto their mobile phone and pair the wristband. As the patient goes about their daily life, the wristband transmits collected data for vital physiological indicators to the paired mobile phone via Bluetooth. The mobile phone then transmits real-time data over cellular or Wi-Fi Internet connections to the hospital network’s backend server where AI algorithms automatically analyzes the data to pinpoint actionable information about the patient’s health.

Since exercise or even taking a shower can also raise a person’s body temperature, the algorithms also factor in the patient’s heart rate to rule out false positives. What’s more, the algorithms combine the patient information with data from a regional outbreak map to improve the accuracy of the temperature warning. For example, if a patient was near a communicable disease vector and other abnormalities are detected during the observation period, the patient will be prompted to return to the hospital for further examination. If no abnormalities are found, the patient will be informed of the completion of the observation period and return the wristband to the hospital.
