Sensory　adaptation　plays　a　critical　role　in　humans　interacting　with　the　environment.　Inspired　by　humans,　realization　of　sensory　adaptation　on　robots　can　make　them　adapt　to　the　environment　gradually.　The　gradual　change　of　sensitivity　that　depends　on　recent　experience　of　external　stimuli　is　the　most　important　process　for　the　adaptation.　To　realize　sensory　adaptation,　such　change　of　sensitivity　needs　to　be　realized.　It　is　proposed　to　fabricate　the　memristor　based　on　single-crystalline　LiNbO3　thin　film.　The　resistance　of　the　memristor　can　be　changed　monotonically　and　gradually　with　the　increase　in　the　number　of　voltage　pulses,　which　can　be　ascribed　to　the　property　of　single-crystalline　thin　films.　Based　on　the　characteristic,　it　is　proposed　to　use　the　memristor　as　artificial　synapse　of　the　proposed　bioinspired　system,　using　conductance　of　the　memristor　to　denote　susceptibility　value　to　realize　the　gradual　change　of　sensitivity　by　recent　external　stimuli.　A　novel　general　excitation　method　of　signals　from　multimodal　sensors　on　memristor　is　proposed　and　utilized　in　the　signal-coupling　module　of　the　system,　which　makes　the　system　realize　sensory　adaptation　for　different　stimuli　accepted　by　multimodal　sensors.　Using　artificial　sensory　memory　systems,　sensory　adaptation　on　robot　is　realized　for　the　first　time　herein.
