This dry-land fish swims to the music of connected, hand-held MP3 or iPod players and has a built-in speaker for operation without a headset. In addition, the unit has multicolored flashing lights and produces sound effects. Even without connecting the I-FISH, its face and tail light up and it wiggles to the beat of music when it is placed in front of a speaker. Depending on the song, the unit displays one of four music-based personalities — for example, country music soothes it. Touching the top of its head triggers a “fish song.” Analog circuitry provides the amplification for the speaker and for powering the array of LED lights.
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.
