Associate Professor
Graduate School of Science and Engineering
Ibaraki University

Outline

The applicant is aiming at a compact ultrawide bandwidth(UWB) photonics-based radar system by combining the integrated Terahertz silicon photonics (TSP) radar module together with a specifically designed laser source for the millimeter/THz band 3D imaging system. Combining both techniques, the proposed system can achieve high spatial resolution, compact size, and lightweight. Since the millimeter/THz signal is down-converted from the optic domain, the proposed technique is flexible to generate the required frequency bands based on actual demands. Throughout this project, we aim at ~40 GHz bandwidth at the 40-GHz band and >100 GHz bandwidth at the 300-GHz band UWB radar module, which can be mounted on a commercial drone with a payload of <200 g.

Outline

Foamed materials are focused on as materials with superior lightweight and heat insulation properties, and a modeling method using an FDM 3D printer has been proposed. However, it requires a special filament that contains a substance that generates bubbles when heated, making it difficult to control the localization of the foaming position. Thus, this project aims at developing a technology to perform computer-controlled electrolysis on the melted filament of a 3D printer. This technology allows the users to generate bubbles dynamically during 3D printing and enables the personal fabrication of various types of foamed objects.

Keisuke Osawa

Hand rehabilitation assist device for remote and home use

Researcher
Keisuke Osawa

Research Assistant Professor
Faculty of Engineering
Kyushu University

Outline

Due to the spread of infectious diseases, it is difficult for therapists to conduct rehabilitation interventions in contact with patients as before. In previous studies, the proposed hand rehabilitation assist device can support finger flexion/extension only. Therefore, they are limited to supporting the recovery of grasping and tapping motions, and are insufficient for the recovery of fine finger motions. In this research, we aim to develop a hand rehabilitation assist device that can actively support finger flexion/extension, adduction/abduction. This will make advanced hand rehabilitation for remote and home use.

High-power biophotovoltaic systems based on an evaluation of microalgae response to osmotic shock by utilizing a micro vortex.

Researcher
Makoto Saito

Graduate Student
Faculty of Engineering
Kyushu University

Outline

Biophotovoltaic systems are progressing technologies producing clean energy from sunlight and storing carbon in microalgae. Although previous researches report that membrane proteins play key roles in the transportations of electron carrier, no earlier work investigates the transportability of membrane transporters. In this research, we present a high-speed osmotic shock system by utilizing a micro vortex to evaluate dynamic responses of membrane transporters in microalgae. Because the vortex allows the osmotic shock in the order of sub-millisecond, we can induce and observe high-speed dynamic responses of transports such as volume, response time and repeatability. In this method, we will reveal the effects of these response characteristics to biophotovoltaic systems and enhance its electric power by selecting superior microalgae.

Keitaro Shimada

Ultrafast snapshot 3D camera based on optical imaging

Researcher
Keitaro Shimada

Graduate Student
Graduate School of Engineering
The University of Tokyo

Outline

Ultrafast imaging is important for technological development in many fields, because it enables analysis of various ultrafast phenomena such as laser ablation and discharge in water. However, conventional methods can only acquire profiles in 2D space and cannot acquire dynamics in 3D space. This project aims to develop an ultrafast 3D camera, a novel optical technique that acquires the 3D video in a single shot with less than nanosecond resolution, to visualize the 3D dynamics of ultrafast phenomena. The ultrafast 3D camera will promote the elucidation of the mechanisms of various ultrafast phenomena and contribute to the advancement of science and technology in a wide range of fields, including processing and medicine.

Outline

In recent years, machine tools have tended to become more multiaxial and dynamic due to increased machining freedom and integrated production of large parts. However, this trend is accompanied by a decrease in accuracy and stiffness, so compensation technology based on high quality sensor information is essential. The objective of this project is to construct a comprehensive error correction system that is independent of machine configuration and machining process. We will develop and install ‘sensory organs’ capable of measuring temperature and vibration at several hundred points to achieve refinement beyond the inherent performance of any processing machine.

Outline

In this study, I develop a granules-size (less than 3 mm square) MEMS (Micro Electro Mechanical System) vibrational energy harvester for a wireless sensor which is so small that one would not be aware of its presence. In particular, a technology for reducing the chip size to less than 1/50 of the conventional size is newly developed by the third-dimensional intensive integration of an electro-mechanical transducer using an electret. The wireless nodes driven by the proposed energy harvester provide IoT (Internet of Things) sensor network that optimizes the environment for an individual.

Takafumi Morita

Development of autonomous-drive biomimetic fluid interfaces

Researcher
Takafumi Morita

Assistant Professor
Interfaculty Initiative in Information Studies
The University of Tokyo

Outline

Fluid interfaces have been attracting attention as a driving force for soft motion because they are lightweight and can freely change volume. However, handling fluids requires large external devices, making it difficult to drive autonomously. In addition, these devices make a lot of driving noise, which hinders soft movement. Therefore, we propose an autonomous-drive fluid system for biomimetic fluid interfaces that can generate and control fluids with low power consumption and sustainability, as well as a sensing technology that utilize unique characteristics of fluids.

Tomohiro Morita

Biological 3D printer for induction of angiogenesis

Researcher
Tomohiro Morita

Graduate Student
Graduate School of Information Science and Technology
The University of Tokyo

Outline

Endothelial cells exists in the innermost wall of blood vessels, and they not only protect the blood vessel wall but also play a role in generating new blood vessels with capillary size and supplying oxygen to the surroundings. Previous researches have shown that when multiple endothelial cells are in close proximity within a collagen gel, they generate new blood vessels to connect each other and form a vascular network. Based on the above, in this research, we aim to develop a 3D printer that capsulates endothelial cells in collagen gel like beads and precisely arranges them in tissues. We expect that the range expantion of vascular network construction in tissues can be achieved by using this printing system.

Creation of photo-rechargeable battery charging only by light irradiation

Researcher

Research Staff
Institute of Innovative Research
Tokyo Institute of Technology

Outline

Conventional photo-rechargeable batteries have poor photoelectrochemical characteristics due to side reactions such as photocorrosion occurring at the electrode/liquid electrolyte interface, and the reaction principle is not clear. In this study, instead of liquid electrolyte, a solid electrolyte with high electrochemical stability is used to construct an solid/solid interface where side reactions are suppressed. By applying band engineering to this interface and controlling the diffusion of photo-excited carriers, carrier lifetime, etc., we aim to create photo-rechargeable batteries in which spontaneous and reversible photocharge proceeds.

Assistant Professor
Faculty of Enginnering

Outline

Osmotic power generation is a renewable energy generated from the salinity gradient. Despite high resistance and high fabrication costs of ion-selective membranes, reverse electrodialysis power generation technology does not meet industry standards. Finding a suitable membrane structure and materials to control ion transport is a major problem that needs to be solved at this stage. This research involves making a series of nanopores with different geometries and sizes to comprehensively investigate the ion transport properties of single pores and arrays of pores. And try to develop the relationship between the geometry structure of solid-state nanopores and power generation efficiency.
