Biomimetics: Technology Imitates Nature


              like those in the eye, with a structure similar to
              the retina’s neural network. Also as in the reti-
              na, these light receptors are connected to oth-
              ers, allowing the electronic circuit components
              to communicate with one another, just as reti-
              nal cells do. 94

                   Despite all these efforts, however, it’s
              proved to be impossible to imitate the retinal network’s circuitry, because
              of the vast number of individual cells in the living retina and the connec-
              tions between them. Design engineers, therefore, are now trying to un-
              derstand how the retina’s neural network operates and are designing sim-
              pler circuits which, ideally, can perform similar functions.
