Claim 21:
22. The device of claim 1, wherein the spacers have a center to center distance of 200 μm or less, and the Young's modulus of the spacers times the filling factor of the spacers is equal to or larger than 20 MPa, wherein the filling factor is the ratio of the spacer contact area to the total plate area; and wherein one of the plates is flexible, the thickness of the flexible plate times the Young's modulus of the flexible plate is in the range 60 to 750 GPa-μm, and the fourth power of the inter-spacer-distance (ISD) divided by the thickness of the flexible plate (h) and the Young's modulus (E) of the flexible plate, ISD4/(hE), is equal to or less than 106 μm3/GPa.
