This document summarizes an electrical simulation of the radial artery conducted by a group of biomedical engineering students at Sir Syed University of Engineering & Technology. They used COMSOL software to simulate the artery due to its ability to model physiological systems. The group measured bioparameters of the radial artery using ultrasound and defined electrical conductivity and relative permittivity values for tissues in the simulation. They varied the interelectrode distance and electrode size to determine the best configuration for applying an electric field without affecting surrounding tissues.

- 1. ELECTRICAL SIMULATION OF RADIAL ARTERY GROUP MEMBERS: JALAL UDDIN (2010-BM-63) MUHAMMAD UZAIR QADRI (2010-BM-23) MUHAMMAD AZEEM (2010-BM-17) WAJIH ABIDI (2010-BM-58) COURSE : MODELING AND SIMULATION INSTRUCTOR: DR.ENGR.

- 3. PLATFORM FOR THE SIMULATION OF ARTERY The software use for simulation of radial artery is COMSOL.
- 4. Why using COMSOL ? Comsol is a software containing multiphysics or cophyisics. physiological model could easily design and Simulate. Is a most advance model designing tool or platform which is incorporated with other fourth generation languages i.e. MATLAB, LABVIEW, SOLID WORKS etc.
- 5. STEPS TO CONSTRUCT A MODEL Select the following in sequence: Dimension Add physics (multiphysics) Study type Suitable unit Geometry Material Mesh Then finally we simulate the model by computing.
- 6. RADIAL ARTERY ANATOMY A major artery that follows the course of the radius on the ventral aspect of the forearm to the wrist, where it is felt as a pulse, and enters the hand. It supplies blood mostly to the thumb, index finger, and muscles of the forearm.
- 7. RADIAL ARTERY BIOPARAMETERS With the help of ultrasound the following observations are found i.e. Depth of radial artery === 3.5mm Diameter of radial artery === 2.3mm Radius of radial artery === 1.15mm
- 8. ELECTRICAL CONDUCTIVITY It is a measure of a material's ability to conduct an electric current. Electrical conductivity of following bioparameters found to be: Stratum === 0.0005S⋅m−1 Epidermis === 0 .95S⋅m−1 Dermis === 0.322S⋅m−1 Muscle === 0.66S⋅m−1 Radial Artery=== 0.8S⋅m−1
- 9. RELATIVE PERMITTIVITY It is the ratio of the permittivity of a substance to that of free space or vacuum, relative permittivity is also called dielectric constant. Relative permittivity of following bioparameters found to be : Stratum === 1F/m Epidermis === 31.3F/m Dermis === 31.3F/m Muscle === 1F/m Radial Artery === 1F/m
