Measuring 7.2 x 7.2mm, these RoHS-compliant have a spherical actuator design for multi-directional, off-center actuation of ± 30. They come in a choice of silver of gold-plated contacts over nickel-plated stainless steel, with terminals made out of either silver or gold, both over nickel-plated brass. Electrical ratings have a maximum power of 0.4W for the gold and 1W for the silver. Both metals have a current range of 1mA-50mA, and a voltage range of 20mV-50VDC. All versions have 0.4mm travel to make. The STJ Series has 130gF, 200gF, 300gF, and 500gF actuation choices. The STJV, the right-angle version, has 200gF or 300gF actuation force. The STJ and STJV both have a stainless steel actuator and actuator cover with 6/6 Nylon switch housing, and the STJV's bracket is tin-plated steel.
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.
