Extracting ECG-based cardiac information from the upper arm:

I identified a total of three locations on the upper arm that provide the most information regarding ECG.

I then identified a pipeline for heartbeat detection with the most robustness against muscle contraction, which is SWT. Later, I improved SWT performance both in heartbeat detection and PQRST delineation using Zephlet and mother wavelet optimization.

Designing and building an electric wheelchair controlled by EOG signals:

I was highly involved in all phases of this project, including electrical circuit design, implementation, mechanical design, wheelchair control, and real-time data analysis. We altered a mechanical wheelchair to an electric one, recorded EOG signals using the circuits we designed, analyzed them in real-time to extract desired commands, and finally controlled the electric wheelchair by EOG signals. What an amazing project!
