Characterization of heating, monitoring, and heat-insulting performances of ITTD. (a) The heating temperature as the function of applied heating power. (b) Relative electrical resistance changes of the top and in situ temperature sensors under various temperature changes. (c) Temperature curves of the heating surface and the unheating surface at 220 mW with the corresponded thermal images embedded. (d) Steady temperatures of the heating surface and unheating surface at various applied heating powers. (e) Temperature reduction rate (TTR) of the PDMS, G-PDMS, and G-HGM ITTDs at different powers. (f) Temperature adjustment curves with a small change of 0.7°C.
