Thermal fluctuations of 8 Pd/Cr micro-TFTCs under different conditions. (a) Thermal fluctuations of 8 Pd/Cr micro-TFTCs (A6, B7, C4, D4, E4, F4, G5 and H2 located in different Testing Zones of different regions) tested in an ordinary laboratory kept at 25 °C, which were exposed to the air. (b) Thermal fluctuations of the same TFTCs tested in the double-stabilized constant-temperature system kept at 32 °C, which were covered by culture medium.
