It's getting tough to tell e-ink technologies apart from each other these days, but Toronto-based Opalux is hoping that its new system has what it takes to stand out from the pack, and it's apparently already well on its way to commercializing it. The secret ingredient here, according to MIT's Technology Review, are photonic crystals made out of silica beads, which measure a mere 200 nanometers across and are embedded in a spongy electroactive polymer sandwiched between transparent electrodes. The crystals can then be made to reflect varying wavelengths of light by altering their spacing, letting the pixel reflect any col
