Design and Implementation of a IoT based Smart Digestive Health monitoring device for Identification of Digestive Conditions

Over the past few decades, there has been a significant rise in wearable healthcare technologies that have been playing a major role all over the world in monitoring health and alerting individuals during deviation from their normal health conditions and assisting them to stay fit and healthy. The present healthcare technologies proven to track many health parameters such as Heart Rate, Blood Oxygen Saturation, Body Temperature, Blood Pressure, Physical Activity, Sleeping patterns, etc. Due to the modern lifestyle and consumption of unhealthy food products, there’s been an adverse effect in digestive health standards. According to study report on 2020, in every 1 million, 4 lakh people are suffering from the Gastrointestinal (GI) tract disorders.

In this work, a wearable device with textile electrodes is designed and developed to analyze the digestive conditions namely pre-prandial and post-prandial using Electrogastrogram (EGG) signals. Further, the proposed device will be comprised of cloth wear with textile electrodes as a sensor, Analog to Digital Converter (ADC) with Programmable Gain Amplifier (PGA), Microcontroller with inbuilt WiFi module and Internet of Things (IoT) cloud platform. Any person can wear the proposed cloth wear inside their regular clothing. Also, the proposed cloth wear with three different textile electrodes made of silver-plated nylon which will be fabricated in three distinct places of the clothing according to the standard electrode placement protocol. Once the clothing is worn, the electrode will rest at the stomach area so that it will be ready to collect EGG signals from the abdomen over the stomach. Further, the acquired signals will be fed to the controller for further analysis.

The objective of this work is to design and develop a smart wearable device to alert/notify the persons once they skipped their food habits on time. Also, the day wise food intake with respect to time will be stored in the IoT Cloud platform for later references. Since the proposed device is compact and can be integrated in usual cloth wear, the device shall be used to monitor the digestive habits namely pre-prandial and post-prandial conditions effectively which leads to healthy life.
