Analysis of Coagulation Effect in Veins using MEMS Laminar Flow for Early Heart Stroke Detection

In the recent past researchers are working on different designs of biomedical equipment to measure various health parameters. People are more stressed due to their routine lives due to their work environments. Therefore, they suffered with health issue such as heart stroke and so on. This research article designated in the article is to design an electronic model to measure health parameters. Pressure and velocity across the veins are treated as inputs and their respective results as outputs. While veins are expanding and contrasting when pressure and velocity of the blood is varied, this is due to stress and exercise etc. The major parameters in detecting the laminar flow are pressure and velocity. The primary objective is to model a veins in different shapes. Second objective is to analysis of flow measurements pressure and velocity of blood cross it. The third objective is to detect blockages of artery due to fatty and cholesterol containing deposits build up over time. The final objective of the design is to describe the working principal of digital stethoscope and wrist band to measure the health parameter of heart through blood pressure. Digital Stethoscope principle depends on piezoelectric effect, generates electrical signal when pressure is applied from veins of the body. Accuracy, functionality, and Performance of the design can be analyzed using COMSOL Multiphysics. MEMS is used in real time applications to alert heart stroke, Bionic eye and automotive electronics etc.

I. Introduction

Most of the environments now a days are highly pressurized to get the most effective throughput. Due to this, many young working professionals are ill-health in their early stages, which leads to heart stroke in the long run. Micro electromechanical system (MEMS) is a miniaturized device with a combination of electronic features inbuilt on a mechanical structure. The primary functionality of MEMS can act as a switch and can also perform as a transducer. The MEMS sensor consists of a mass suspended between two capacitive plates, where the suspended mass makes a difference within the electric potential. The size of MEMS ranges from micro to millimetres [1]. The advantage of MEMS sensor model is tiny in size and applicable for all types of portable and consumable applications. Some of the other applications that includes flow measurement, heartbeat, blood pressure etc. The values across the veins operated under different degrees from the designed model. Simulation and verified under laminar flow and analysis of the design being done useful alert in case of heart stroke[2]. Pressure and velocity of veins are analysed by incorporating valves across the veins. Laminar flow of blood in veins are captured by MEMS-based piezoelectric sensor by the functionality. Performance of the design depends on the accuracy of the inputs applied to laminar flow. The concept of coagulations is measured by MEMS module at the second stage of heart attack by placing MEMS with stent. As the size of stent is also in millimetres[[3]-[4]]. it is feasible to attach the MEMS sensor with the stent.
