Abstract :
Bioengineering is different things to different people. To a nurse with a broken power cord on a blood pressure monitor, bioengineering is what gets it fixed. To a medical researcher, bioengineering is the design of instrumentation to measure something. To your grandfather with a heart pacemaker, bioengineering is what keeps him going. Using a textbook definition, bioengineering is the application of physical and mathematical principles to biological and medical problems. That covers a lot of ground. Bioengineering can be the use of metallurgy to develop replacement hip joints, or the use of plastics to replace blood vessels, or the signal processing of ultrasonic echo.
