These puppies do more than just sit there and look cute. Sensing a human presence, the interactive, battery-powered toys react with actions and sounds. Motion includes head tilting and movement from side to side. The unit makes several sounds include whimpering, happy panting, soft whines, snoring, playful growling, playful barking and a waking-up noise. Touching the pooch’s nose instigates a low growl. Analog functions include the amplification for the sounds, actuating the motors and motion and touch sensing. Converting the motion sensor’s signal to an input for the microcontroller requires analog circuitry for threshold detection.
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.
