December 30th, 2017 Posted by IOT PLATFORM 0 thoughts on “IoT-based Heart Rhythm Monitoring”

Abstract

This paper describes the design and implementation of a prototype of IoT based heart rhythm monitoring system in order to get the wave pattern of irregular and normal sinus rhythm of a person that needs a diagnose of having a heart problem and alert the personnel of unusual behavioral reading of beats per minutes (BPM). The system will sense the cardiac rhythm and also identify the user their pulse rate reading in BPM. The system is connected to IoT cloud based where the data is stored and notifies any unusual behavior.

 

Introduction

Heart rhythm is the signal of heartbeat where it can be view in waveform signal. A normal heart rhythm is called normal sinus rhythm (NSR). An NSR will have a heart rate (pulse) between 50 and 100 beats per minute (BPM) and a normal impulse formation from the SA node (P wave)[1]. Each individual’s normal resting heart rate will vary and can range from 40 to 120, higher in young children. A certain amount of variation in heart rate throughout the day is normal as activity levels vary. Even though an individual’s regular rhythm may not exactly fit, into the category of normal sinus rhythm, it does not necessarily suggest that a problem exists. In addition, even if an individual’s rhythm is normal, it does not preclude underlying heart disease[1].

The graph in Figure 1.1 shows the waveform classification of ECG wave. A normal heartbeat waveform consists a continuous sequence of PQRST waves. The P waves represent a normal heart’s depolarization process. The QRS wave represents the rapid depolarization of the right and the left ventricles. The T wave is generated during the heart ventricle repolarization or recovery[3].

IoT based Heart rhythm monitoring is a system that monitors the rhythm of the user while they at home or outside of a hospital. The device uses to track the pattern of rhythm that changes during everyday life activity. It served as help tool to the doctor to monitor the user without user come to the hospital to undergo tests. In addition, the physician able to real-time monitored the user condition by website application. The changes in heart rate of the user are continuously monitored and detected in form of a value of heartbeat per minute (BPM) and the data that collected is send to the IoT cloud platform and an alert message will be sent to the respective person for further notice if the threshold value set is over limit. Furthermore, the device is designed to be comfortable to the user to wear every day.

 

Design and Implementation

This section details the implementation system. The system runs in a sequential form: patient – device – server – web application – personnel (doctor).

Figure 2.2: Flowchart of the system

The system aimed to read the blood flow volume inside the user to read the human pulse or heart rhythm and beat per minute. The sensor used the PPG system where it used reflective type PPG system where the intensity of reflective light received inside the photoresistor is converted into a waveform signal. Thus, the first step is the pulse sensor wrap to the index finger of a user. Secondly, the data transfer from the pulse sensor will undergo algorithm calculation to display the Beat per Minute. In another way, the signal also transfers to the IoT platform for storage and retrieve to the web application to view the displayed of heart rhythm signal.

Preliminary Result

This section shows the preliminary result from the prototype testing for waveform pattern for normal people that don’t have a heart problem.

The device is connected to the Favoriot platform to store the BPM reading as it will monitor and notify the personnel is unusual BPM reading reads.

An alert message will be received when the BPM reading exceeds the threshold value stated.

Conclusion

The prototype is a success in monitoring and notifies the respective personnel in sending an alert when unusual behavior reading is recorded in IoT platform, thus can conclude almost 70% of the project is done.

Future Works

The next step to complete the system is the monitoring of the waveform pattern on the real-time monitor and a comparison between the irregular heartbeat and normal heartbeat. Thus, a web-based application will be created with the help of SQL database to store and compare the waveform pattern with the database of irregular heartbeat get from trusted resources.

Smart Bracelet for Elderly People: Fall Detection, GPS tracker, ​and Medicine Reminder

December 30th, 2017 Posted by IOT PLATFORM, SMART HEALTH 0 thoughts on “Smart Bracelet for Elderly People: Fall Detection, GPS tracker, ​and Medicine Reminder”

Abstract

The Smart Bracelet for Elderly People is an innovative solution that aims to detect and locate people especially for elderly people with a health problem. It is designed as a remote alert system for people at risk of stroke, sudden heart attack, and seizures. The smart bracelet provides fall detection system, GPS tracker to trace the current location and a medicine reminder setting to remind pill intake on time. This device is synchronized with the FAVORIOT platform which stores GPS data and fall detection indicator.

 

Introduction

The Smart Bracelet for Elderly People is an innovative solution that aims to detect and locate people especially for elderly people with a health problem. It is designed as a remote alert system for people at risk of stroke, sudden heart attack, and seizures. The smart bracelet provides fall detection system, GPS tracker to trace the current location and a medicine reminder setting to remind pill intake on time. This device is synchronized with the FAVORIOT platform which stores GPS data and fall detection indicator.

The bracelet can be used for elderly people staying alone when the child lives elsewhere. The child can monitor the condition of their parent which will avoid worrying feeling at all times. If a bracelet detects any fall that threatens their parent life, the device will automatically send an email or alert message to the child then if the parents do not answer the phone, we’ll know something might happen to them.

Other than this, the smart bracelet has a tracking system that has access to GPS technology. This means that the parent can spend their time outside of their home to do shopping, sport and other. In the case of a parent may be lost and fall outside of their

home, the bracelet can provide accurate location of their parent. Another functionality of the smart bracelet act as medicine reminder to remind elderly people to take their pills; if it is neglected, this service warns the prescribed care provider. It provides an easy-to-use dispenser that helps maintain the appropriate medication schedule. Elderly patients hear audio reminders when it’s time to take their pills.

Design and Implementation

The smart bracelet is designed based on Arduino UNO which is selected as the microcontroller. The Arduino is connected to accelerometer sensor for fall detection. GPS module for location tracking and a real time clock module for medicine reminder. The buzzer is connected to alarm sound when it is time to take the medicine. The block diagram of the systems is as shown in Figure 2.1 below.

Conclusion

The smart bracelet is able to send an alert message to the children if their parent fall and they can take immediate and necessary action. The medicine reminder reminds the elderly people to consume prescribed medicine. The GPS tracker only and can locate the current location of the elderly people. As human life longer nowadays, we believe that this device becomes important device near the future.
