MOTION CONTROL:Steinmeyer Inc.’s new precision linear stage, the PA 30×40-SM01 is a single axis system ideal wherever there is a need for an extremely narrow positioning table. Typical uses include miniature robotics, pick and place devices, specimen handling for life sciences and scientific applications where precision positioning is required within a very narrow foot print. This compact, fully enclosed stage is only 30 mm wide and 40 mm high. Available travels range from 25 mm to 150 mm. Positioning repeatability is 1 micron, maximum speed is 50 mm/s and load capacity is 100 newton. Included inside this precision assembly are a precision preloaded 8 mm diameter Steinmeyer ball screw, miniature size 9 linear guideway, non-contact limit switches and a choice of either stepper motor or dc servo motor with encoder. A separate motion controller is available as an option.
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.
