Thermally Conductive Rubber ("Thubber") for Passive Cooling of Heat-Generating Hardware Embedded in Soft Goods Space Technologies

In this SBIR project, we will develop a passive thermal management system for microelectronics that are integrated into space suits, gloves, and other soft goods. The system will be composed of a thermally conductive rubber that is molded around the heat-producing components. In order to enable mechanical deformation, the microelectronic components will be wired together with soft and stretchable circuitry. In general, the circuit wiring can be any soft conductor that maintains low electrical resistivity when stretched. For the purposes of this project, we will use wiring composed of a non-toxic, biocompatible eutectic alloy of gallium and indium.
