Parker Hannifin engineers state that they are seeing heavy interest in hydraulic valve technology from the marine industry (including those people who make those several-hundred-foot-long yachts) in applications as wide-ranging as bow thrusters and tugboat control to sail and winch control. The reason? Recent advancements in proportional valve technology, allowing for quicker and more accurate holding of an actuator's position. "At one point, the marine industry thought that electric motors would be the panacea that would solve all of their problems from reducing cost to lowering power consumption, and obviously eliminating the issue of hydraulic leaks," says Michael Gudhe, industrial product manager for the company's Hydraulic Valve Division. "Now they're rethinking hydraulics and recognizing the benefits they bring to the table," he says. Or perhaps he should say deck.
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.
