Project Summary

The modern industrial world is highly vulnerable to biological disorders that are very dangerous and destructive to human health. Over the last decade, chronic diseases and an aging population have led to a greater interest in wearable physiological measuring devices. Our device will solve common health problems such as pain, blood pressure and diabetes. The common body vitals include glucose level, heart rate and body temperature. To date, the level of glucose has been determined by an invasive method which is to take blood by pricking the finger and then measure the sugar level in it. But we're introducing a non-invasive technique to measure sugar level without hurting the patient.

The second objective is to ease the pain. Pain is a vital function of the nervous system to alert the body to potential or actual injury. It's both a sensory and an emotional experience. The traditional way to relieve pain is through the ingestion of medication, which is likely to have some side effects. A safer solution is therefore needed.

In addition, recent research has shown that about 25 per cent of the world's population suffers from type 1 diabetes and 80 per cent from type 2 diabetes and has high blood pressure. Most people have worse health problems because they are not aware of their health records because of their busy lives. Approaching a doctor on a daily basis is another difficult and costly issue.

Our project is mainly based on the technology of transcutaneous electrical nerve stimulation (TENS), non-invasive methods and the Internet of Things (IoT). The project aims to relieve pain with the help of TENS technology, monitors and measures body vitals through a non-invasive method. We are designing a multi-functional portable device consisting of a microcontroller, pulse oximetry sensor for oxygen level & heart rate, temperature sensor (DS18B20) and electrodes.

Purchasing separate devices for these different issues is quite expensive and difficult to carry. We are therefore creating a compact system that incorporates all these different functions. In addition, our system ensures improved efficiency and accuracy.

Project Objectives

• To develop a portable, a cost-effective, and a compact multifunctional device using non-invasive techniques.
• To provide pain-relief solution with the help of TENS.
• To monitor and measure the body vitals such as temperature, heart rate, and oxygen-levels.
• To display useful information that guides the patients about their current health status on the device screen as well as on the mobile phone.  
• To utilize “things speak IoT platform” for storing of patients’ health information and sharing that information to a doctor as well as to the patient.

Project Implementation Method

The project is mainly based on micro-controller supporting multiple inputs (heart rate sensor, oxygen level, temperature sensor, and electrode pads). Moreover, IoT is also utilized in this project along with a mobile app to display the readings and precautions on a smartphone screen. These technologies will be integrated together to develop a compact, portable, efficient and economical device.

In the Fig-1 inputs are processed in the micro-controller using programmable conditions and mathematical equations to give out the desired outputs. All the outputs will be taken in the form of physical quantities except glucose sensor output; glucose level will be checked by analyzing the oxygen level in the blood. Oxygen and glucose in the blood are inversely related to each other, therefore low oxygen in the blood would mean high glucose level and vice versa.

Figure 1. Pain-relieving and Body-vitals Monitoring and Measuring System

To relieve pain, our TENS unit utilizes electric impulses to stimulate nerves for therapeutic purposes. The electric impulses are given to the targeted area of the body through electrode pads.  TENS uses integrated circuits to generate waves of optimum frequency (depending on the RC time) It operates within the current range of about 25 microamps to 900 microamps for therapeutic use with a peak current of 6 milliamps. The current is applied to the parts of the body through a pair of electrodes in the form of a high frequency, monophonic, a burst of a D.C. carrier signal (at least 10,000 Hz to 19,000 Hz) that is chopped or modulated at a relatively lower frequency (about 0.3 Hz up to 10,000 Hz). The burst of the modulated carrier signals has a duration of about 0.05 seconds to 10 seconds. Preferably, the modulating frequency is selected from pairs of frequencies that exhibit specific therapeutic action (e.g., 292 Hz and 9.125 Hz). For routine use, a frequency of 9.125 Hz to 292 Hz is particularly useful. The present design also provides a unique LED electrode that produces electromagnetic radiation synchronously with electrical current therapy.

Benefits of the Project

It will be a compact, portable and an economical device providing an instant pain relief solution for pains such as Lower-back pain, Arthritis and post-operative pain along with real-time monitoring of body vitals such as temperature, heart rate and blood glucose. It will measure patient’s glucose level with a non-invasive method which will be an innovation in medical field. Furthermore, it will keep record of patient’s health status and notify the doctor if patient’s condition is critical.

Technical Details of Final Deliverable

It will be a compact device with the functionality of relieving chronic pains and taking your important body vitals like heart rate, body temperature, oxygen level and most importantly, measuring sugar level by a non-invasive method. The device is also capable of sending these health records to your doctor or family members in case of an emergency. Moreover, it can display instant health precautions that a patient should take to avoid hospitalization.

It will be a relief for the patients to get rid of a number of medical devices for their different health problems as our device is highly convenient, compact and easy-to-carry. In addition to these relaxing facilities, our device provides efficiency and ensures high accuracy too.
