Estimation of Stimuli Received by Cell Through Signal Visualization

This paper presents the author’s research on the estimation of sensory information of a cell by using signal visualization. As a single-celled creature, the signal transduction between Paramecium’s interior and its surroundings through the plasma membrane is controlled by a logical sequence. The objective of this research is to develop a method in which this signal transduction within an organism, in this case a Paramecium, can be estimated through signal visualization. The use of microorganisms, and Paramecium in particular, as microactuators has already attracted several researchers such as Itoh [3], Fearing [2] and Ogawa [6] in the area of dynamic motion control. Many microorganisms that can barely be seen with the naked eyes are surprisingly well equipped in terms of actuators and sensors. A Paramecium has actuators and sensors all-in-one inside its 150μm length, 40μm diameter semi-elliptic volume.
