Sunlight sensors detect the amount of solar radiation to improve air conditioning efficiency and provide a higher comfort level for driver and passengers in vehicles with separate cooling zones. Hamamatsu's S8369 sensor uses a photodiode to measure the infrared heat load of the sun's rays and a special cap shape to achieve a wide-angle of directivity. The one-piece plastic package design integrates the sensor assembly and connector in a single housing. The unit has a spectral response from 320 to 1100 nm. To meet passenger compartment requirements, the sensor has an operating temperature of -30 to +80C. Custom versions address different specifications, including multiple zones, and added functionality. For more information on Hamamatsu's sunlight sensor go to: http://rbi.ims.ca/4914-501
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.
