The National Science Foundation is funding a collaborative effort between NASA and the University of Buffalo's Department of Physics to develop a new type of shock-absorbing system that may one day protect skyscrapers, bridges, shops, and automobile bumpers from powerful impacts. Surajit Sen, an associate professor of physics at the university, designed the new shock-absorbing system that consists of a long, cone-shaped chain of spheres. The sphere positioned closest to the expected source of a shock impulse is the largest. Each subsequent sphere is slightly smaller, with the smallest sphere positioned closest to the thing needing protection from shock. As mass is reduced, the energy of the impulse is distributed, according to Sen. He envisions a structural material embedded with chains of the spheres.

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.
