The effect of the dielectric layer material on the electro-osmotic mobility. (a) Variation of electro-osmotic mobility with the change in the gate voltage for 2400 Å CVD oxide and 12 μm spin-coated PDMS. (b) Plot of mobility vs coefficient of ACd in Eq. 4. The double layer capacitance Cd is estimated from the slope of the curve.
