A new sensing mechanism based on an imitation of the phototransformation of plant

The final goal of our research is to develop a new engineering system. Here, we attempt to apply the mechanism of a plant sensory organ and growth to an element that consists of an engineering system. In this paper, the mechanisms of the phototransformation of a plant phytochrome and its germination control are proposed as the new mechanism of a sensing and control. Moreover, the bed system was implemented as one example of an engineering system with our proposed mechanism. The performance of this bed system was examined, and then the potential of realizing the new bed system with the sensing function of the concept of protecting a user's privacy was clarified. This result shows the possibility of applying a function of the phototransformation of a plant phytochrome and its germination control to a new mechanism of sensing and control field.
