FIG. 2.
Characterization of microfluidic channels prepared using Q7-mixtures. (a) A sketch of a single straight channel and (b) the channel stretched along the y-direction. (c) The strains of the channel length (ɛl) and width (ɛw) compared with the strain of the whole chip (α). (d) The strain of the channel height compared to the strain in the chip. (e) Typical I–V curves of measured for the microchannel before (blue curve, square symbols) and after (green curve, circle symbols) stretching with a chip strain of ∼150%.
