Flexbeam-2(TM) beam-style flexible couplings are one-piece aluminum components which incorporate spiral cuts to accommodate angular and parallel misalignment and axial motion. The one-piece design and cut pattern ensure zero backlash and minimal wind-up. The couplings incorporate two sets of two spiral cuts and are for precision applications, especially those that use delicate components such as encoders and tachometers. The small bearings on these components make low radial forces essential to longevity and continued high performance.

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.
