  1. Unbreak My Heart: Bioengineering

  2. What is Engineering? • The major goal of engineers is to improve our quality of life. • Take known technologies and improve them OR • Create new technologies

  3. Bioengineering is… • Application of engineering principles to biology and medicine • Pictured here: Artificial Knee

  4. What is Bioengineering? Chemistry Biology Medicine Bioengineering Materials Science Engineering Computation

  5. Some Specialty Areas • Lab on a chip • Tissue scaffolds • Artificial limbs • Imaging • Appearance

  6. Who are Bioengineers? Computer Scientists Chemists

  7. Imaging technique that detects an object based on how well it “echoes” sound waves Used to detect heart defects, age of fetus, position in uterus, twins Can determine sex of baby by week 18 or 20 of pregnancy Also used to thermally apply medications to injuries Example: Ultrasound

  8. How Ultrasound Works: Forming the Image Producing a Sound Wave Receiving a Sound Wave

  9. Strengths/Weaknesses • Strengths • Easily detects soft tissue and muscle • Renders “live” images • Detects structures of organs • Weaknesses • Cannot penetrate bone • Doctor dependent interpretation • Possible dangers • Heat generation • Bubble formation

  10. Quick Question: • What is a “Biomaterial”? • Do you have a biomaterial in you? • Do you know of a family member that has a biomaterial?

  11. What are biomaterials made of? Glass Metal Pyrolytic carbon Plastic Ceramic and Metal

  12. Early Medical Devices

  13. Early Dental Devices Tooth Extractor Root canal tools Drill for cavities

  14. Early Medical Devices Artificial Hand Stethoscope

  15. Early Medical Devices Civil War Amputation Kit Arrow Extractor

  16. What bio-materials can you see?What problem do you think they are solving?

  17. Common problems with biomaterials: Body breaks implant down Calcification (bone forms on valve) Blood clots on the surface

  18. Back to the Beginning: • Looking back at your definitions of “bio” and “engineering”, is there anything that you would change or add? • How would you change the model of your solution after viewing this presentation? • Take some time with your group and compare ideas.

  19. How do I become a Bioengineer? Bachelor’s Degree (College) PhD (Graduate School) • 4 Years • Prepare for company job, graduate school, or medical school • Apply last year of high school • 4-6 Years • Research in a specific area of interest • Master’s or PhD • Can be a professor

  20. What to expect… Computer Programming Thermodynamics Calculus+++ Physics Chemistry Fluid Mechanics Statics & Dynamics Electrical Circuits

  21. Start Preparing Now! • Core Subjects: Math and Science • Take 4 years of both math and science in HS • Geometry, Algebra, Statistics, Calculus • Biology, Chemistry, Physics • PSAT and SAT • Can take the PSAT and SAT in middle school • Prepare by studying and working with a tutor • Join Math and Science Clubs or Extra Activities
