The Le Mans 24 Hours is one of the most ambitious races there is, testing the endurance of drivers and their machines. Mega-Line Racing Electronic GmbH, which is providing the absolute magnetic shaft encoder in the Audi R10's transmission, has turned to solid-state sensors to improve lifetimes. Mega employs austriamicrosystems' AS5243 redundant magnetic angular position sensor, using it to measure the absolute position of the barrel shaft in the gearbox. That optimizes the whole gear change sequence. The compact 7 mm sq Hall Effect sensor is contactless, so there's no wear, improving reliability.
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.
