Georgia Tech Professor of Electronics James Gole has an idea that may reduce the voltage consumption of biomedical sensors. He uses porous silicon and a unique metallization process for a new sensor that detects gaseous compounds. Unlike other sensors based on porous silicon, Gole and his collaborators reduce the resistance of the electrodes built into the silicon, allowing the sensor to operate between 1 and 10 millivolts. "It operates on a voltage much less than that of a watch battery," says Gole. "It is small enough to be taken into the field with a troop contingent or any other group concerned about the presence of harmful gases." The sensor is based on a silicon wafer and operates at room temperature. It is manufactured using integrated circuit production techniques. Gole says the sensor could be integrated into electronic equipment and used for making sensing arrays. For more information, call Gole at (404) 894-4029 or send e-mail to email@example.com.
Imagine being able to illegally download a physical product the same way you can with music and videos. That’s basically what’s happening with 3D printing and digital manufacturing, with huge repercussions in the intellectual property domain.
Ford will be the first automaker to commercially use Alcoa's tough & fast Micromill aluminum alloy process and materials, debuting on several 2016 F-150 truck components. Alcoa will also license its Micromill process and materials technology to Danieli Group.
