Introduction to Biomedical Engineering Capstone Project
Key concepts, typical structure, and best‑practice guidelines
1. What Is a Capstone Project?
| Aspect |
Description |
| Purpose |
Integrates knowledge from coursework, labs, and internships into a real‑world engineering solution. |
| Scope |
Usually 1‑2 semesters (≈ 12–24 weeks) of design, development, testing, and documentation. |
| Outcome |
A functional prototype or validated concept, accompanied by a technical report, presentation, and (often) a poster. |
| Stakeholders |
Students, faculty advisors, industry sponsors, clinical partners, and institutional review boards (IRB) when human subjects are involved. |

2.1. Phase Details
| Phase |
Main Activities |
Deliverables |
| Problem Identification |
Literature review, clinical need assessment, interviews with clinicians. |
Problem statement, preliminary market/clinical gap analysis. |
| Feasibility Study |
Technical, regulatory, economic, and ethical feasibility. |
Feasibility report, risk matrix, IRB/ethics check if required. |
| Requirements Definition |
Functional, performance, safety, usability, and regulatory requirements (e.g., FDA 21 CFR 820). |
Requirements specification (REQ‑DOC). |
| Concept Generation |
Brainstorming, sketching, trade‑off studies, selection criteria matrix. |
Concept list, concept ranking, selected concept justification. |
| Design Specification |
System architecture, block diagrams, interface definitions, Bill of Materials (BOM). |
Design specification document, preliminary CAD/Simulink models. |
| Detailed Design |
Component sizing, material selection, detailed schematics, software algorithms. |
Detailed CAD drawings, PCB layouts, software flowcharts, simulation results. |
| Prototype Development |
Fabrication, assembly, firmware/software integration. |
Physical prototype, firmware build, test fixtures. |
| Testing & Validation |
Bench testing, benchtop validation, pre‑clinical testing (e.g., tissue phantoms, animal models). |
Test plan, raw data, statistical analysis, validation report. |
| Iteration/Optimization |
Design tweaks based on test feedback, repeat testing as needed. |
Updated design files, version control logs. |
| Documentation |
Technical report (IEEE format or university template), design history file (DHF). |
Final report, design history file, user manual. |
| Presentation & Defense |
Oral presentation, poster session, Q&A with faculty and industry panel. |
Slide deck, poster, recorded defense (if required). |
| Reflection & Future Work |
Lessons learned, scalability assessment, potential commercialization path. |
Reflection essay, roadmap for next development phase. |
