Improved performance at the system level results from improvements in one or all of the subassemblies in the system. Completing the design could mean adding a right-angle gearhead, an incremental encoder or a controller. Improved performance could come from lower-backlash in the gearhead, higher resolution from the encoder, or the ability to control up to six motion axes. Here are examples in each of these areas.
Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
Sharon Glotzer and David Pine are hoping to create the first liquid hard drive with liquid nanoparticles that can store 1TB per teaspoon. They aren't the first to find potential data stores, as Harvard researchers have stored 700 TB inside a gram of DNA.
