Basically, if it involves engineering and medicine, there’s a good chance a Biomedical Engineer is involved!
II. The Core Principles: The Engineer’s Toolkit 🛠️
To tackle these complex challenges, BMEs need a diverse toolkit. Here are some key principles we rely on:
-
Biomaterials Science: Understanding the properties of materials and how they interact with biological systems. This is where we ask questions like: Will this material be rejected by the body? Will it degrade over time? Is it strong enough to withstand the stresses of daily life?
Material Type Properties Applications Metals (e.g., Titanium) Strong, biocompatible, corrosion-resistant Implants, prosthetics, surgical instruments Polymers (e.g., Silicone) Flexible, can be molded into various shapes, biocompatible Catheters, drug delivery systems, breast implants Ceramics (e.g., Alumina) Hard, wear-resistant, biocompatible Dental implants, bone grafts Composites (e.g., Carbon Fiber) High strength-to-weight ratio, biocompatible Prosthetic limbs, bone plates -
Biomechanics: Applying the principles of mechanics to biological systems. We analyze forces, stresses, and strains in the body to understand how it moves and functions. This is crucial for designing prosthetics, understanding injury mechanisms, and optimizing athletic performance. 🏃♀️🏋️♂️
-
Bioinstrumentation: Designing and developing instruments and devices for measuring biological signals. Think EKGs for monitoring heart activity, EEGs for measuring brain waves, and blood glucose monitors for managing diabetes. 📈
