ABB Drive Operations has unveiled the "world's fastest microdrive," the ACS/140. The unit covers from 0.5 to 3 hp, as well as 230 and 460V ac, in single- and three-phase configurations. It can respond to input signal changes in as little as 9 msecs. Measuring just a fraction of the size of conventional PWM ac drives, the new ACS/140 MicroDrive includes firmware and software for commercial and industrial applications. Applications include: fans, pumps, mixers, agitators, compressors, and conveyors. It also features a standard PID controller for simultaneous control of an industrial process or HVAC application.

Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
