Nobody likes to find that a simple unplugged connector is the cause of a failure that shuts down a system for a long time. That's especially true when a hard-to-reach plug is on an orbiting spacecraft. NASA's hoping to avoid that type of problem with a rewrite of its Specification S-311-P-822, which addresses connectors. When Compact PCI connectors are selected for NASA space flights, Hypertronics Corp.'s cPCI connectors with the Hypertac “Basket of Wires” are now a connector of choice. Connectors from the subsidiary of the Smiths Group have already been used on the Solar Dynamics Observatory, the Mars Science Lab., the Hubble Space Telescope and the Lunar Reconnaissance Orbiter.
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.
