the sensory systems based on the signals from the corresponding artificial sensors.
For example, lux and decibel are the units to quantify lights and the sounds, re-
spectively . Furthermore, such standard signals can be sent over a long distance and
utilized to reproduce the corresponding stimuli. For example, one can take a picture
using a camera comprised of photosensors, send it through the internet, and repro-
duce it on display devices, which is one of the key technology in the modern IT and
entertainment devices such as smart phones and televisions. Thus, one of the key
events which triggered modern IT and entertainment industries can be the develop-
ment of artificial sensory devices for human eyes, ears and touch senses.
We can envision the development of bioelectronic noses and tongues may trig-
ger the similar progresses in the future. The signals from the bioelectronic noses
and tongues can be utilized to quantify the stimuli for human noses and tongues ,
respectively. For example, the standard signals from perfumes or foods (i.e. wine,
coffee etc) measured by bioelectronic noses or tongues can be sent over a long dis-
tance and used to evaluate the smells or tastes of them, respectively. Eventually, we
may be able to develop advanced devices to reproduce such smells or tastes from
the standard signals, which may open up the new era of modern entertainment and
IT industries. In this sense, we may say that the development of bioelectronic noses
is a major breakthrough in modern technology and we are at the dawn of a new
technological revolution.
