Live tissue bioactuators have been proposed as a new form of actuator. In this study, transgenic light-regulated dorsal vessel of Drosophila Melanogaster larva was used as a bioactuator. Feedback control of a bioactuated robotic arm using optical stimulation of the bioactuator and visual feedback of arm's end effector was performed. In this study, we investigated the response of the bioactuator to localized optical stimulation. The contraction displacement of bioactuator increased as total stimulated area of the bioactuator increased. Then, by varying total stimulated area of the bioactuator, we demonstrated position control of the robotic arm in a closed-loop system using visual feedback.

Insects are extremely successful animals, living almost everywhere on the earth and their body fluid is rich in sugar. If electric power can be generated with their sugar, the insect will become an on-site power source. Our group has already reported a trehalase-glucose oxidase based BFC using trehalose of insect hemolymph. In this research, we proposed an iBFC with self-circulation system and developed the self-circulation system powered by the body fluid circulation in insect body. We also developed the AuNP-based BFC which oxidizes glucose by a catalytic reaction of AuNP in order to prevent the degradation of the output by deactivation of enzymes.

Automation of piezoelectric inkjet-based single cell printing is the target of this study. Piezoelectric inkjet technology capability of high speed printing is the main advantage of this technology over other technologies. Therefore, this technology has gained attention in recent field of tissue engineering. Additionally, this technology was successfully developed for single cell handling. However, automation system for the single cell handling was not yet developed. In this study, utilizing open source image processing library, OpenCV, to process image of the inkjet head, automatic cell detection system was successfully developed. Finally, combining cell detection system and cell printing system, automation of single cell printing system with 98% successful ratio was successfully developed.

This paper proposed a Multiple Microfluidic Stream based Manipulation (MMSM) system for biological object using micro hydrodynamics and Lab on a Chip (LOC) technology. Our method can implement the function of micro manipulation and micro assembly of bio-objects without contact in an open space. Compared with other conventional bio-micro manipulation and assembly methods, this system is manipulating a micro object by controlling multiple microfluidic streams onto it from various directions. The advantage of this method is open space, multi-function, multi-scale, multi degree of freedom, and non-invasive three dimensions manipulation. These microfluidic streams are generated simultaneously from multiple orifices. By regulating the parameters of the microfluidic stream such as flow rates, position and number of operating orifices, the direction and velocity of the object can be controlled. To verify this principle, we designed an open space fluidic system for on-chip manipulation. The results presented in this paper showed that this MMSM has the capability for Micro Bio-manipulation.
