- The diverse vision systems found in nature can provide interesting design
inspiration for imaging devices, ranging from optical subcomponents to digital
cameras and visual prostheses, with more desirable optical characteristics
compared to conventional imagers. The advantages of natural vision systems
include high visual acuity, wide field of view, wavelength-free imaging,
improved aberration correction and depth of field, and high motion sensitivity.
Recent advances in soft materials, ultrathin electronics, and deformable
optoelectronics have facilitated the realization of novel processes and
device designs that mimic biological vision systems. This review highlights
recent progress and continued efforts in the research and development of
bioinspired artificial eyes. At first, the configuration of two representative eyes
found in nature: a single-chambered eye and a compound eye, is explained.
Then, advances in bioinspired optic components and image sensors are
discussed in terms of materials, optical/mechanical designs, and integration
schemes. Subsequently, novel visual prostheses as representative application
examples of bioinspired artificial eyes are described.© 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
