What do you think bioengineering encompasses?Slide3
The Scope of Bio
Bio-engineering applies the basic principles of engineering to the development of innovative methods for the diagnosis and treatment of diseases and injuries as well as playing a crucial role in the advancement of medical devices and technologies. It is an interdisciplinary subject, which combines wide-ranging scientific knowledge with technological processes and engineering skills to provide systems for many applications.Slide4
Continued…
Bio-engineers can be involved in a diverse array of fields including
bio-materials and biomechanics, magnetic resonance imaging (MRI), computing and image processing, nuclear medicine,
ultrasonics
, nanotechnology and can include the application of mechanics to musculoskeletal and cardiovascular systems. Bioengineers can be involved in developing systems for the rejuvenation and maintenance of sustainable environments.Slide5
Continued…
Bio-engineering can involve designing and developing new instruments for monitoring the performance of human organs, such as the heart, developing information structures, such as computer generated models of joints, like the hip or knee, as well as creating new materials for bio-engineered articles, such as artificial hearts and cochlear implants. Bio-engineering involves any area of human exercise where an article or system is developed that will replace or enhance a body organ or function. Slide6
Nature and Range of Work
There are many areas of bioengineering, including:
Bio-mechanics – deals with the mechanical functioning of parts of the body, such as joints and
limbs
Bio-materials – deals with the study of materials that are compatible with living
tissue
Bio-instrumentation – relates to the design and development of instruments that can be used to monitor and measure bio-engineered devicesSlide7
Bio-computing – relates to the development and application of computer programs that will simulate
biophysics
Rehabilitation engineering – relates to the design and development of rehabilitation equipment, such as wheelchairs and
crutches
Systems physiology – involves the observation and measurement of physiological events, for example the electronic impulses between muscles and hands. Slide8
How many examples of bioengineered devices can you think of?Slide9
Did you answer…
Contact lenses;
Glasses;
Dentures;
Prosthetic limbs;
Cochlear implants;
Crutches.Slide10
Current innovations
There are many biomedical engineering products being developed in Australia (as of 2012), including:
Assessing knee joint strength in osteoarthritis;
Developing a bionic eye device;
Building targeted drug-delivery systems for cancer and other medical treatments;
Developing tools to predict and control epileptic seizures;
Development of synthetic materials that can regenerate lost or diseased bone and cartilage.Slide11
Relations with the Community
Bioengineering is highly regarded across the community, as it is beneficial to our quality of life.
Can you think of the positive and negative impacts that bioengineering has on the community?Slide12
Positives and Negatives
Positive impacts:
Access to technology and procedures in remote communities;
Improved quality of life and longevity.
Negative impacts:
“Playing God”;
Use of animals for research;
Failures that sometimes occur;
Access to procedures and devices - $$$Slide13
