What is a Biosuit?What is a Biosuit?

• A Biosuit is any kind of protective suit that enables a human to maintain homeostasis while working in an environment that would not support human life.

• Examples: Space Suit, Hazmat Suits, Wet Suits etc.

Why do we need BioSuits?Why do we need BioSuits?• The systems of the body participate in maintaining

homeostasis, that is, the relative constancy of the internal environment despite external environmental changes.

• What does each system need in order to support the human body in maintaining homeostasis?– Respiratory System-– Circulatory System-– Digestive System-– Immune System-– Excretory System-– Integumentary System-– Nervous System-

Where do we use Biosuits?Where do we use Biosuits?

• Biosuits are used in environments where the temperature, air pressure, amount of oxygen in the atmosphere and other factors are not conducive to a human maintaining homeostasis.

• Examples: The ocean, space, Arctic regions, hazardous environments etc.

• Neoprene- a family of synthetic rubbers. Exhibits good chemical stability, and maintains flexibility over a wide temperature range. (used in wet suits, laptop sleeves, knee braces etc.)

• Mylar- a polyester film used for its high tensile strength, chemical and dimensional

stability, transparency, reflectivity, gas and aroma barrier properties, and electrical insulation.

• Include all members.• Create a back story that is creative and maybe

even funny about your group.• Talk about your design, and explain what each

feature is and how it would be represented if you had real materials.

Presentations-Performance TaskPresentations-Performance Task

• Explain what your human model is doing as they perform the task.

• Describe how the features you created are helping to complete the task.

layer or Mylar?• Could felt represent nylon layers used in the

space suit?• Could rubber represent neoprene?Be creative and explain thematerials you use, and how they compare to “real world”materials.
