| Outline of Final Research Achievements |
Bacteriorhodopsin (bR) is a photoreceptor membrane protein extracted from the cell membrane of Halobacterium salinarum which lives in saline lakes. Irradiation of bacteriorhodopsin on the interface of electrodes and the electrolyte generates a time-differential photocurrent, which results in a signal that responds only to changes in the intensity of light without the need for an external power supply. By using two types of bR with different optical response characteristics, the optical flow detection known as a visual information function of an insect is attained. We have developed a novel optical-flow sensing method using a bipolar photosensor array with bR wildtype and its variant (D96N).
