Introduction Biomedical Engineering

• Biomedical Engineering (BME) is an interdisciplinary field that applies principles of engineering and design to the medical and healthcare industries.
• It combines concepts from mechanical, electrical, chemical, and biological engineering to solve problems related to human health.
• Biomedical engineers design and create medical devices, equipment, and technologies, as well as work on developing systems to improve the quality of life for patients.
• BME is a dynamic field that bridges the gap between engineering and medicine, contributing to advancements in healthcare through technology, innovative treatments, and diagnostic tools.

Key Areas in Biomedical Engineering

1. Medical Device Design and Development
