Multi-level laminated bus bars feature capacitors, mounted with pressed-in-knurled connectors designed to hold the axial capacitor leads, and insulated gate bi-polar transistors (IGBTs), which are bolted to the surfaces. The bus bar connects IGBTs and capacitors in parallel, through the dc link of this circuit, to distribute power to the motor. The individual copper layers use offsets to locate various contact surfaces to their required locations.

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.
