This paper proposes a thin active fixture that holds a human body to attach and detach an exoskeleton with less effort and time. This fixture does not become wearer's burden due to a light weight and interfere with finger motions due to a thin shape. A required time to attach/detach a grasping support exoskeleton to/from fingers and a wrist by our fixtures is shorter than one of Velcro.

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.

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.

A needle biopsy is a kind of the inspection to extract the muscles under the skin with a needle, the inspection method accelerated the research on muscle characteristic and a sick of muscle. Current needle can extract only the muscular tissue of a limited structure. Based on the above background, we work in research and development of novel needle biopsy system in order to extract muscle tissue with form of fiber. The system consists of an ultrasonic device, an angular adjustment implement, and a needle. The needle has curved shape so penetrates from skin surface perpendicularly and takes route parallel to bone in muscle tissue. When the needle is inserting in muscle, pressure are given for muscle tissue. And then reaction force was given to the tip of needle. We designed prototype of the needle's tip using reaction force to close. We report in this paper developing needle biopsy system and designing tip of needle.

This paper reports on development of a micro glucose sensor integrated-device for cell-based assays. Glucose is the energy source of living cells. Therefore, measuring the glucose consumption on cells is very important in cell biology. In μTAS research field, an enzyme-fixed micro glucose sensor integrated to microfluidic devices has been proposed for measurement of cell kinetics continuously. There are various methods on how to fix the enzyme to the sensor. In this paper, we examined the performance of the micro glucose sensor fabricated by the different enzyme immobilization methods. We measured the sensitivity and the lifetime of the glucose sensors made by different enzyme immobilization methods. As the result, the sensor sensitivity of the crosslinking method was higher than it of the physisorption method. We conclude that the performance of the micro glucose sensor could be modified by optimization of the enzyme immobilization methods.

We developed a highly functional stent to treat the cerebral aneurysm what is one of a cerebrovascular disease. The stent has a valve part to path through a coil. The valves have fractal structures. So, the blood flowing into cerebral aneurysm is prevented. We performed a Particle Image Velocimetry (PIV) experiment to evaluate the inflow into cerebral aneurysm. By the experiment result, we visualized the stream line by using the cerebral aneurysm. By calculation, we succeeded in a 55% reduction in the inflow by using the valve fractal stent.

In this paper, we investigate an alternative double-stranded probe (dsProbe) system as detection platform that employs a similarity-based classifiers in DNA strand displacement reactions. We formulate label propagation based on DNA toehold domain as classifier, where a node propagates to neighboring nodes according to their proximity. We observe mismatch attributes of DNA strand sequences to recognize the effect of this model. The attributes are position, length and location number of mismatches. We carry out simulation using Nupack software and also experimental investigation..

We present the fabrication of catalytic driven micro-nano robot by direct laser writing. The micro-nanorobot has a spiral design of 3,5, and 7 μm named D1, D2 and D3 respectively and a flat top design D4. The micro-nanorobot is catalytically driven in 6% hydrogen peroxide (H2O2) from platinum catalytic area. The result shows that the spiral micro-nanorobot increased in speed except when the micro-nanorobot exhibits the drilling motion. It showed spinning motion, self-propulsion and drilling motion for micro-nanorobot D1, D2 and D3 respectively. The flat top micro-nanorobot has the highest speed and spinning motion was displayed. Future studies should include the actual pollutants in the environment and the effects of the drilling motion on its final content should be observed.

Recently, various wheelchair robots are developed for improvement of usability of wheelchair. There are some types in users of wheelchair. We focused on users of wheelchair who live in the area far from their family or care giver. Because of depopulation and aging in rural area, it is expected that the number of such users of wheelchair increases. It is please them to go out and talk with their family or care giver. However, the family or the care giver can't easily to go to see him or her because it takes a lot of time and cost to go. And then we decided to develop a remote controllable wheelchair robot with the function of telepresence. On the other hand, the remote control is too risky for a local user of wheelchair robot. A wheelchair robot must be driven safely by a remote user. The purpose of this study is to improve safety of driving of the wheelchair robot by a remote user. We supposed that it is able to relieve the fear of local user and a remote user by improving a function of emergency stop. We conducted experiment to survey the size of comfortable space of a user on wheelchair robot.

This paper describes a DC voltage estimation at the maximum power point of a series parallel connection photovoltaic (PV) system with partial shade. The PV system converts sunlight into electric power. The IV (current-voltage) curve of the solar cell describes its energy conversion capability at the existing conditions of light level. The PV (power-voltage) curve which determines the maximum output power is computed from the IV curve. It is necessary to operate the solar cell at the voltage which provides the maximum power. The maximum power point tracking (MPPT) control using hill-climbing method is widely used. However, the output power from the PV system is reduced if weather condition changes and the area of the receiving portion of the PV panel decreases. In these cases, IV characteristics of the PV panel also changes. There is a possibility that the maximum power point cannot be captured by the conventional MPPT control in case that the maximum power would be two or more. We propose a method for the estimation of the DC voltage at the maximum power point by using the equivalent circuit of the solar cell.
