ABSTRACT
The almost-perfect examples of sensors are in the human body, with the senses continuously supplying real-time data to the brain. By using our sensory elements (eyes, ears, skin, nose, and tongue), all perceptible information contained in our environment can be obtained. Then, by speci‘c and ideal signal transducers, this information is selected, ‘ltered, and processed in the most wonderful natural computer, the human brain. Finally, depending on the results, humans react in a short period of time.
