The electronic nose in Lilliput
Article Abstract:
The Swiss Federal Institute of Technology developed an experimental CMOS-based odor sensor. The device is small enough to fit into a wristwatch. The design was based upon two parameters. First, it must be able to detect organic solvents in the air, and determine the specific chemical. Changes in polymers' physical properties form the basis of this micronose. CMOS IC is shown in an illustration, along with various diagrams, charts, and a list of defined terms. Microbalances are subjected to a sample, and the changes in resonance of the balances are then measured. A second sensor measures changes in capacitor function. The third type of sensor on this micronose utilizes changes in surface temperature as the gas is absorbed by the sensor.

Around the world in a solar plane
Article Abstract:
Bertrand Piccard, who was the first to circle the world in a hot air balloon, hopes to be the first to circumnavigate the globe in a plane powered entirely by photovoltaic cells called 'Solar Impulse'. His efforts to achieve this feat with the help of scientists and engineers at the Swiss Ecole Polytechnique Federale de Lausanne (EPFL) are presented.
