Self-Sustaining Space Suit in Works

To use body heat for energy

Researchers say a next-generation space suit could monitor astronauts' health and use their body heat to power electronics.

Developed at Kansas State University, the space suit would incorporate biosensor technology to keep track of astronauts' vitals, such as breathing rate and muscle activity.

The reseachers, who include students and professors, are also looking to use the temperature difference between body heat and the space suit's cooling garment to power radios and other electronics.

Batteries are too dangerous to place in an astronaut's oxygen-rich space suit, researchers told The Associated Press, spurring their interest in new energy-harvesting methods.

Producing spinoff technologies, such as new radio technologies and devices that apply to home care, will comprise the last part of the unversity's research.
