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.

This Gadget Freak Review looks at a keyless Bluetooth padlock that works with your smartphone, along with a system that tracks your sleep behavior and wakes you at the perfect time in your sleep cycle to avoid morning grogginess.
Siemens released Intosite, a cloud-based, location-aware SaaS app that lets users navigate a virtual production facility in much of the same fashion as traversing through Google Earth. Users can access PLM, IT, and other pertinent information for specific points on a factory floor or at an outdoor location.
Since 1987, teams of engineers around the world have built solar cars to participate in a road race around Australia called the World Solar Challenge, being tested on the race time, kilometers traveled, practicality, and energy used by the vehicles they invent.
