Short Overview on our IEEE Research Paper:

Project Overview
Our project focused on designing a commercial-grade circuit using semiconductors, logic gates, and timing components to simulate a real-world biomedical alert system. The goal was to create a functional, reliable, and testable design ready for real-world application. The system monitors three critical cardiac indicators: elevated troponin levels, ST segment changes on ECG readouts, and blood oxygen saturation (SpO2) drops. The goal was to create a functional, reliable, and clinically testable design ready for real-world hospital application.

Design Process
We began by outlining requirements and selecting components like 555 timers, D flip-flops, and basic logic gates. Using LTspice and KiCad, we simulated the circuit, refined it, we then built multiple iterations on breadboards for rapid prototyping and real-world testing, allowing us to identify design flaws early and implement improvements. This iterative approach included feedback from medical professionals to ensure clinical relevance.

Testing & Tools
Our testing included visual inspection, power checks, and functional validation. We used LTspice for simulation, KiCad for PCB design, and breadboards for rapid prototyping. The process helped us understand limitations and refine our design for reliability.The process helped us understand circuit limitations and refine our design for reliability in medical applications.

Conclusion
This project taught us how to move from concept to a tested circuit ready for field use. It reinforced the importance of thoughtful design, simulation, and testing in creating practical engineering solutions. The project demonstrated how electrical engineering principles translate into biomedical applications that impact patient care. Most importantly, we developed appreciation for interdisciplinary collaboration between electrical engineers, biomedical engineers, and medical professionals in creating effective healthcare technology.
