Keeping devices operating at adequate temperatures is necessary for numerous technological areas. One innovative component that can contribute to this control is the thermal switch (TS). TSs rely on the switching of thermal resistance between two states: during the “on” (“off”) state, the thermal resistance is minimized (maximized), thus maximizing (minimizing) the heat transfer. In this...
