Texas Instruments' new ROM-based C280x and Flash-based F280x digital signal controllers are optimized for motor control, and are said to be particularly well-suited to such applications as electronic power steering and integrated starter-alternator control. Both processors employ a patent-pending Pulse Width Modulator (PWM) with 150 ps resolution, reportedly making them about 64 times more precise than competing processors. One member of the family — the TMS320F2809 — offers 256 Kbytes of on-chip Flash and six PWM channels of 150 ps resolution.

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.
