Umeshika Uthayakumar.jpg

I obtained BSc (Hons) in Electrical and Electronic Engineering at Sri Lanka Institute of Information Technology and currently working as an Assistant Engineer in Sri Lanka. I'm highly interested in pursuing my post graduate studies in the areas of renewable energy, sustainability, power systems and intend to establish myself as an Electrical Engineer by contributing to the development of Electrical Engineering field. My Bachelor's research was based on Wireless Power Transfer for Cardiac Pacemaker.

Wireless Power Transfer for Cardiac Pacemaker[edit | edit source]

Cardiac pacemaker is an electronic device used to regulate the heartbeat of patients suffering with congenital heart defects. Considering the limitations in lifespan of current cardiac pacemaker battery, a wireless charging mechanism for cardiac pacemaker is proposed in this paper. Circuitry model and electromagnetic geometry is developed using Ansys Maxwell and Ansys High-Frequency Structure Simulator (HFSS) software to analyze three main technical issues such as: implantation, efficiency and safety. Specific Absorption Rate (SAR) and induced electric field in a 3-D model human body is evaluated by numerical analysis and simulation to ensure that the developed system adheres to safety limits proposed by Institute of Electrical and Electronics Engineers (IEEE) standard and International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines.

IoT based smart energy meter for houses [3rd year project][edit | edit source]

Nowadays, people are wasting more electricity which results in the energy wastage and increase in monthly electricity bills. In addition, the life time of electrical appliances reduces due to over usage. Therefore, it is needed to replace the appliances frequently which result in high cost and also causes environmental pollution as more wastage is disposed.

Smart energy meter is a device which measures the household power consumption and provides a billing system through a mobile app so that the user will be concerned of their upcoming monthly electricity bill. The smart energy meter measures the current and voltage and calculates the power consumption and optimize it to get the energy usage by saving the data on a SD card to analyze the electricity usage. This device would be more efficient as the system is made out to display the power consumed by each section of the house so that the user may concerned on electricity consumption. This will result in reduction of electricity bill as well as saves electric energy. The current smart meters which are available in the market are designed to output live results, whereas, this project is focused on data collection and analysis to overcome the energy wastage.

Mini solar power plant [1st year design project][edit | edit source]

The mini solar power plant concentrates on harnessing solar energy by rotating the solar panel for 180 degree using Arduino Uno to charge a 12VDC battery. A motor is fixed to the rotating solar panel and controlled by Atmega 328 microcontroller in Arduino Uno board. The solar panel rotates from one horizon to other to find the position where greater solar energy could be absorbed to charge the battery. Hence, the solar panel can be adjusted to be incident towards the sun to harness maximum energy with more efficiency.
