Auto supplier Johnson Controls has unveiled a number of environmentally friendly innovations and new materials in a concept hybrid car. The car has a plug-in hybrid battery in the trunk that provides for low-emission operation.
The car also includes new substrate materials processed from natural fibers to replace interior plastic. The front seat structures are constructed of lightweight materials designed to lighten the total weight of the car. The car is made of aluminum and steel that are combined using special welding processes to further reduce weight and improve mileage.
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.
