Ambient Corp. has designed a compact system that helps people who can't speak because of neurological disorders, traumatic brain injury, cerebral palsy or other problems. Its Audeo, a wireless sensor worn on the neck, captures the wearer's neurological activity going from the brain to the vocal cords. This activity is digitized and turned into speech, letting users communicate in person or by phone. A Texas Instruments' MSP430 microcontroller uses little power and manages overall consumption so the Audeo can last more than eight hours on a single charge.
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.
