| Research Abstract |
Taste receptors of animals consist of taste cells with varied responsiveness to taste substances. Also our recent findings showed that taste cells form cell-networks within taste receptors, suggesting the crosstalk between taste cells. Neither irregular responsiveness nor crosstalk has been avoided in engineering. However, animals utilize these properties to have taste receptors perform excellently. In this study, we proposed chemical sensors inspired by taste receptors with multiple perspectives including electrophysiology, computer science, and integrated circuit engineering. We showed that non-compensated sensors assembled into networks reproduced animal taste responses in the discrimination of taste qualities and intensities. These results suggest that animal taste receptors supply ideas to utilize irregular parts that have been rejected and crosstalk has been neglected as noises.
