While the total number of engineering degrees earned is on the decline, the good news is that more and more people with an extra X chromosome are pursuing the degree. The number of female undergraduate engineering students has increased from 44,431 in 1979 to 72,393 in 1998. Overall, females now make up 19.7% of the undergraduate enrollment—though the percentage is higher at some schools, like MIT (42%). Numbers come from the Society of Women Engineers.
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.
