ABSTRACT
In this chapter an introduction to artificial perceptual sensors, their properties
and possible applications are viewed. Also, a deeper understanding of possi-
ble structures is provided with a clear aim to generally apply artificial sensors as
“extended” tools in conjunction with the human perception system. By the word
“extend”, the meaning is viewed as to displace the point of sensing remotely away
from the human body. For example, instead of using our biological tongue to get
in direct contact with food compounds, a rather attractive and convenient thought
is to make use of an artificial sensor system. The system can then conveniently
in an external process assess and evaluate the quality of a food, e.g., by using an
electronic tongue system placed in close proximity to the body. This method surely
provides a safer concept and could, at extensively used commercial versions, also
provide a qualitatively more efficient evaluation by complementing the human
organ. The consequence of the new gustatory and olfaction sensor device can be
seen as a new generation of sensors built for an individual’s remote use, that are
able to provide fast and accurate human interaction including a safe approach for
detection outside the body.
