1. A method of fabricating a thermally conductive, stretchable elastomer composite, the method comprising mixing liquid metal and a soft material in a centrifugal mixer under conditions such that the liquid metal forms microscale liquid metal droplets that are dispersed in the soft material, wherein the liquid metal is liquid at room temperature, wherein the composite comprises a strain of at least 100%, and wherein the microscale liquid metal droplets comprise a major axis dimension in a range of 1 to 100 microns.
