  1. What is a TEC? TEC

  2. How do they work? • Current >>> Temperature (seebeck effect) • Hotside-coldside • Direction of current (Peltier Effect) • Cooling human tissue

  3. Pros? Cons? • Smaller, less bulk • Don’t require a medium • Not very efficient (<50%)

  4. Temprature & the body 37 °C (99 °F)- Normal body • 36 °C (97 °F)- Mild to moderate shivering (body temperature may drop this low during sleep). May be a normal body temperature. • 35 °C (95 °F)- (Hypothermia) is less than 35 °C (95 °F) - Intense shivering, numbness and bluish/grayness of the skin. • 34 °C (93 °F)- Severe shivering, loss of movement of fingers, blueness and confusion. Some behavioral changes may take place. • 33 °C (91 °F)- Moderate to severe confusion, sleepiness, depressed reflexes, progressive loss of shivering, slow heart beat, shallow breathing. Shivering may stop. Subject may be unresponsive to certain stimuli. • 24–26 °C (75–79 °F) or less- Death usually occurs due to irregular heart beat or respiratory arrest;

  5. HypothermiaMain article: HypothermiaIn hypothermia, body temperature drops below that required for normal metabolism and bodily functions.
