N2 - This paper reports a novel micro thermal diode with an embedded micro glass thermal insulation structure. The diodicity is given by wettability-driven one-way fluid circulation mechanism without any external force. The water circulation only occurs in "forward" mode, resulting in low thermal resistance. The glass thermal insulation structure enhances thermal insulation in "reverse" mode. The thermal insulation in forward and reverse mode, Rf and Rr, were measured as 2.06±0.34 K/W and 3.04±0.38 K/W, respectively. Therefore, the performance index, R r/Rf, was 1.47±0.14.
