Abstract:
PURPOSE: A method for controlling movement of growing bacteria through vibration mode shape is provided to have desired arrangement of bacteria cellulose. CONSTITUTION: A method for controlling bacteria movement comprises: a step of inoculating bacteria in a culture device which can implement vibration mode; a step of leading vibration mode shape inside the culture device by applying a specific frequency; and a step of controlling bacteria movement to arrange bacteria along nodal point or nodal line generated by the vibration mode. A method for producing bacteria cellulose comprises: a step of inoculating Acetobacter xylinum in the culture device containing Ph-regulated culture medium; a step of leading vibration mode shape inside the culture device by applying a specific frequency; a step of culturing bacteria controlling bacteria movement; and a step of obtaining arranged bacteria cellulose.
Abstract:
PURPOSE: A method for measuring movement displacement of an actuator is provided to measure movement displacement of an actuator through an image, thereby easily measuring the entire movement displacement even though the movement displacement of the actuator is large. CONSTITUTION: A partial image of an actuator, in other words, the region of interest, is separated(S200). In the region of interest, the vertical direction length of the image of the actuator is measured(S300). N coordinate values of the actuator are measured(S400). The vertical/horizontal axis motion displacement of the actuator is grasped through the measured coordinate values(S500).
