Can it be made smaller / lower power? Could it be made really small, like a human nose?
Yes, making the ENose smaller is primarily a matter of designing the electronics to be smaller. How small it can actually get will depend very much on how you want to use it. We get air to the receptors in our noses by breathing. The ENose also has to have a way to get air to the sensors. Right now we use a pump, so the size of the ENose is somewhat limited by the size of pump we can get. In another application, however, such as one where the device moves through the air, the air could be forced into the sensors by the movement. In that case, the ENose could be very small.
