Project Summary

We are aiming to design a strain band that is a device which helps doctors as well as patients to monitor the healing process and for the rehabilitation of patients. Though piezoresistive sensor already exists, flexibility and sensitivity remained a challenge. So, we will design a highly sensitive and flexible soft strain sensor that will be light weighted and compatible with the human body (since we are using a fluidic channel for sensor design that will adopt the shape of a body in case of movement, stress, or joint break). It will detect the change in resistance when stress is applied to the body. Afterwards, it will be embedded into medical electronic gadgets to perform the gait analysis. This device will monitor the motion of wrist, knee (for osteoarthritis), elbow and hand. It will be useful for the biomedical industry specifically for orthopaedic doctors and physiotherapists to treat their patients having Motor Neuron Disease (MND) and Parkinson ’s disease. Both diseases have no cure, but needs consistent monitoring for long period of time and different therapies are available like physiotherapy to help relieve the symptoms and maintain their daily life. These are such kinds of diseases that needed to monitor on daily basis, and it will be hectic and painful to travel daily only for the sake of monitoring. Specifically, the patients from remote areas with such health issues will suffer more in terms of travel routine, travel expenses, poor system of transportation and poor infrastructure of roads. So, by developing this device we will provide relief to them get monitored at home and the doctor will prescribe them accordingly. Moreover, this device will also be used for monitoring the paralyzed patient. This disease demands intensive monitoring for recovery, and it is such type of disease that takes a long time to recover the patient. So, for making this monitoring process easy for both patient and physician, we will develop this sensor-based monitoring gadget that sense, collect, and process the data and will send to the doctor via the internet (Microcontroller module will collect the data from the sensor and will send it to the excel sheet and android application while using google firebase). The data will be accessed by doctors/physicians through an android application. Further, this device also has an application in the sports industry and robotics (for education purposes), in future milestones, we aim to implement this sensor in the field of robotics through machine learning.

Project Objectives

As far as objectives and outcomes from this project is concerned, firstly we have developed the starin sensor with enhanced characteristics including sensitivity, resisivity, conductivity, flexibility, roubustness, flexibility and compatable with human body or skin. Secondly. we have to develop a wearable gadget by using this sensor in order to monitor the movement and to perform gait analysis of patient body parts.This product will be helpful specifically, for the patients of " Paralysis". Furthermore, sports person and an athlete can use it and monitor his/her body movement range and adopt the alloowable range of movement for the effective exercise or workout.This product will reduce the cost of transportation and frquent charges of moniotoring by physiothrapist. And it will provide opportunity to update the body movement conditions to their concerned doctor by remaining at home. 

Project Implementation Method

Mathedology of this project is comprises on the different following steps, which include 3D-printing, Printed Circuit Board (PCB) desigining, Material mixing, Fabrication of sensor using 3D-printed mold, Filling with highly conductive fluide, interfacing of sensor with ESP-32 board for the wireless data transfer in order to monitor the body movements and perform the characterization for designed sensor .

Technical Details of Final Deliverable

1: For the technical details we have designed the sensor then it is aimed to transfer data wirelessly, for that we have used ESP-32 board that can extreact the values monitored by the sensor real time can be used after wards for the applications.

2: We have developed the PCB board for the single sensor data accusition for the monitoring of human body parts and for the five sensors, in order to  control the Nao- Robot.

3: Then we have used Choreographe in order to interface the extracted data with NAO-Robot and to control it.

4: Python was used to direct NAO- Robot accordingly.

Above all mention technologies we have implemented in order to accomplish the applications of the sensor.
