Recently, several studies have reported, the in vitro fabrication of small scale 3D tissues. However, in large cell structures, oxygen and nutrients are not supplied to the inside of the tissue. In this case, cells at the center will die. We propose an automated system for the construction of a fine lattice shaped structure, based on hydrogel fiber to produce active 3D tissues in vitro. To evaluate the proposed system, a fine lattice structure was constructed as a basic experiment of 3D tissue form.

In order to achieve detection of flowing cells in the glass capillary, we proposed the integrated micropipette. In this research, we focused on the fabrication of microcapillary. The fabrication method is based on MEMS packaging technique. Two glass layer; a micro channel and a sensor layer are bonded, and we can get microcapillary with capacitance sensor for detection of cell flowing. By using fabricated microcapillary, we successfully achieved aspirating and detecting of cells flowing in a microchannel.

Due to the increasing number of rehabilitation product related to human-robotic interfaces, tactile sensation will provide excellent hints on the research progress in robotic field. The objective of this research is to study on the decisive factor of human being in differentiating the thickness between two thin foils; which is the stainless steel and copper. In this study, the finite element (FE) simulation of the fingertip's 3D elastic model has been performed by the aid of CATIA V5. From calculated results, we examined the displacement rate of the foil. As a result, the displacement rate for copper (which was monitored at the foil surface) is always higher compared to stainless steel. By comparing with previous psychophysics result, the simulation also proves similar traits; where human subjects discriminate thickness of foil according to material hardness when t <; 100 μm, thickness is undetermined when 100 <; t <; 350 μm and evaluation is done via another system when t > 350 μm.

Hyper-redundant manipulators are an interesting solution for flexible manipulations. While these types of manipulators can be used in complex environments, often their weight becomes impractically heavy due to the large number of actuators required for a large number of degrees of freedom. Biomimetic manipulators have received attention as a possible solution for the above problem, by imitating biological systems in which a large number of joints are driven by cooperation of muscles. However, these approaches often don't achieve the desired weight reduction as a whole system, due to the need for an air compressor. As such, the purpose of our research is a hyper-redundant manipulator designed with the intention of weight saving over the whole system.

This study was designed to investigate whether octacalcium phosphate (OCP) in alginate (Alg) composite promotes osteoblastic differentiation of mouse bone marrow stromal ST-2 cells and composite releases the cells outside after incubation. The results suggested that Alg/OCP composite could be a good device for bone tissue engineering.

User's life-logs include various and useful information. Life-logs can be used for health care and improve daily living recasting his/her daily life. Our aim is monitoring a user's life for acquiring user's life-logs. In previous research, life-logs is acquired using user's GPS data or estimating daily activities. These methods are useful for estimation of what he/she did or where he/she went, however it is difficult to estimate user's likes and tastes. Therefore, this paper focuses on the dialogue with the robot. In this research, the authors experiment to what feature can be acquired through dialogue with the robot for the acquisition of the user's likes and tastes.

We are developing an autonomous robot for power distribution line maintenances. The robot autonomously carries out the maintenance tasks by task-level instructions, for example “Insert the bolt (Fig.1)” or “Clench the nut”. This paper describes program descriptions and a program execution framework for the robot to carry out the tasks by the task-level instructions.

We succeeded in isolating pre-counted small amounts of circulating tumor cells from whole blood. And we also confirmed isolation of CTCs from mouse-CTC model with same method. On our open microfluidic chip, CTCs are isolated by their size-difference from other blood cells. Therefore, we arranged micropillars on the microfluidic chip. Blood sample is injected between chip and inclined coverglass. And then, by suction of blood sample, CTCs are drifted and collected. Near 90% of CTCs were isolated without any pretreatments. We also operated animal testing with same method.

Computer topography (CT) imaging is one of the powerful-tools for nondestructive observation technique. In this paper, we present observation of bone from mice by scanning electron microscope (SEM)-CT system using environmental- SEM (E-SEM). The advantage of this SEM-CT system is able to image in high-resolution with less than 400 nm resolution. We investigated the effects of X-ray wavelengths and intensities to improve the imaging contrast for SEM-CT observation. From experimental results, a porous structures were observed inside the bone sample with approximately 10 μm pores.

In this paper, an electrodeposition method was applied to construct cell patterning structures by an alginate hydrogel. The liver cells (RLC-18) were trapped selectively within alginate structures on the micro-patterning electrodes, which were fabricated by a photo-lithography process in circular, ring, and triangle structures. The living conditions of RLC-18 cells were confirmed until 3 days. These results indicate that biological cells were entrapped inside arbitrary shape hydrogel structures in living conditions. The fabricated 2D biological structures are important to be applied for 3D assembly of biological cells for tissue engineering applications.
