Current spacesuit gloves used by astronauts on the International Space Station (ISS) have sustained cuts during extravehicular activities (EVAs) due to sharp edges and burrs, possibly on damaged ISS handrails. A warning system in the glove would aid in identifying the location of sharp objects and the extent of damage to the glove. This work investigated various e-textile and flexible circuit technologies to determine the best ones for creating a glove cut/damage warning system for integration into a spacesuit glove.

Electrically conductive threads were evaluated and used to develop a pair of prototype gloves to demonstrate how e-textiles can be used to warn the user when and where damage or a cut has occurred on the glove. A pair of gloves with conductive threads, a microcontroller, and a battery were assembled to identify when cuts occur in the high-wear areas of the glove. The goals were exceeded by the incorporation of a program that allows the user to view a graph showing the health of the gloves.

This work shows that an unobtrusive warning system can be incorporated into the glove without any deterioration of glove performance. A real-time cut/damage system would tell the astronaut when damage to the glove has occurred.
