- Smell Nanobiosensors: Hybrid systems based on the electrical response to odorant capture Theory And Experiment. Alfinito, Eleonora; Pennetta, Cecilia; Reggiani, Lino // AIP Conference Proceedings;May2009, Vol. 1137 Issue 1, p115
Mammalian olfactory system is the bio-archetype of smell sensor devices. It is based on a very articulated mechanism which translate the odorant capture information performed by the olfactory receptors (ORs) into a code. Finally, the code is sent to the brain for aroma recognition. Our aim is to...
- Convert signals to proper logic levels. // EDN Europe;Mar2009, Vol. 56 Issue 3, p30
The article offers information on how to convert signals to proper logic levels in the electronic industries in Europe. A signal conditioner needs to have high input impedance since a voltage divider can influence the device under test. The output signals of a signal conditioner must match the...
