a Elasticity (Young’s modulus) of the three wicking materials. b Yield strength of the three wicking materials. c Wicking time for different materials (strips of width 2 mm and length as mentioned in experimental section) (optical microstructures are shown in insets). d Average wicking speed of the fluid in each strip under 0.05 mL/h flow-limited wicking of sweat in the patch (simulation of real scenario); the wicking speed for each strip varies by no more than 9.7% and the mean wicking speed among all strips is consistent within 4.96%
