Also at the show, Astyx Inc. (formerly known as Microwave Technology and Sensors) showed a proximity sensor that detects the distance of near-field (about half an inch) targets, including carbon fiber composites, as well as all types of metals. The new prox sensor represents a departure of sorts for sensing technology, which previously had been unable to detect such composites with great accuracy. Astyx Inc. President Peter Schmitz says the new sensor can detect its distance from a carbon fiber to an accuracy of about 10 µm at a measuring range of about 1 mm.

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.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
