Abstract
We have developed a taste sensor consisting of a multichannel electrode with transducers composed of lipid membranes immobilized with a polymer, i.e., eight different kinds of lipid analogs mixed with poly(vinyl chloride) and plasticizer. This multichannel sensor responds to five basic taste substances in five different ways; the taste patterns composed of eight electric-potential responses could be clearly distinguished from each other for the five basic taste substances. Moreover, similar but distinguishable patterns were obtained for substances eliciting a similar taste in humans. The reproducibility is noticeably improved from those of lipid membranes which were previously investigated for application in a taste sensor. The present results imply that the multichannel lipid membrane device has the ability to sense tastes like a human being.
