Control of magnetic skyrmion dynamics by local ion irradiation method

Researcher
Daiki Oshima

Assistant Professor
Graduate School of Engineering
Nagoya University

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.

Research and Development Initiative
Chuo University

Outline

Soft robot technology is attracting attention for the safe cooperation between humans and machines, however, there are problems with response speed and generated force derived from its softness. In this research, through the development of bundled type explosively fast combustion-driven artificial muscle system using combustion of dimethyl ether (DME), the realization of a soft actuator will be challenged that satisfies the response speed, force, and displacement the same scale as humans. By bundling the artificial muscles, the problems will be tried to solve that it is difficult to control the output and drive it continuously since the proposed method is driven by combustion.

Outline

The early detection of viral infected patients including pre-disease patients is very important for with-COVID society. It allows for rapid isolation and treatment of patients, and result in the improving of survival rates. But a lot of pre-disease patients show no symptoms. As a result, they rarely seek medical care at a hospital, and difficult to confirm diagnosis in the early stages. This project aims to develop the simple-opperating, portable microdevice for early detection of viral infection by analyzing the viral specific DNA or RNA in patients’ saliva, and to build real-time patients’ data network based on the data sent from the developed microdevices.

Researcher

Assistant Professor
Graduate School and Faculty of Information Science and Electrical Engineering

Outline

In this project, flexible spin IoT devices will be fabricated using magnetic multilayer film and magnetic nanoparticles. Generally, the devices using magnetic multilayer film must be annealed. Threfore, because the flexible subustrates normally have low thermal resisitance, new transfer method will be established to fabricate magnetic multilayer film on the flexible substrate. Moreover, for the easy device fabrication, a fabrication process to print a pattern for the spin IoT devices will also be established using inkjet printer with magnetic nanoparticles instead of an ink. Then, the properties of spin IoT devices on flexible substrate under bending stress will be revealed. The insights obtained from this project will be useful in the fabrication process for the flexible spin IoT devices.

Researcher
Takashi Sato

Researcher
Sensing System Research Center
National Institute of Advanced Industrial Science and Technology (AIST)

Outline

The purpose of this project is to create a robust and stretchable electronic device by using liquid metals for mounting electronic components on a stretchable circuit substrate instead of solders. To improve the stretchability of electronic devices, the electrical connection between wiring and electronic components is important. Thus, we use gallium-based liquid metals for mounting to obtain high stretch tolerance and low contact resistance, but the liquid metals have high contact resistance. In this project, we will first measure the contact resistance, contact angle, and oxide film thickness to clarify the factors of the contact resistance, and search for the conditions for low contact resistance. Then, we will create electronic devices with high stretchability and high performance.

Outline

Robot-assisted surgery systems have been used to provide treatment that preserves the function and appearance of organs. However, they lose haptic feedback required for the manipulation of forceps and electric scalpels, and have invasiveness caused by scattering of the laser beam irradiated for treatment by biological tissue. In this study, I develop a robot-assisted laser surgery system that controls the laser-tissue interaction (i.e., treatment effect) to the lesion by non-contact irradiation of a laser beam designed based on biological signal feedback and computational simulation. This system will enable non-contact, non-invasive, and tailor-made treatment.

Researcher
Ryo Takahashi

Assistant Professor
Graduate School of Engineering

Outline

Toward integration of a sensor array into various surfaces in our daily life, it was necessary to design a specific sensor array according to the sensing application and its sensitivity. In contrast, we aim to perform pressure, capacitive, and inductive sensing by simply incorporating the same sensor array pattern and a highly sensitive readout circuit into surfaces such as wall, floor, furniture, and textile. This enables anyone to implement a surface sensor array with the desired sensing functions.

Researcher

Assistant Professor (without tenure)
Faculty of Science and Engineering

Outline

This study aims to develop a material synthesis technology for next-generation biofuel cells (BFCs) by applying nanoscale ultramicro reaction fields. In the conventional synthesis of BFC materials, the reaction rate is slow due to the denaturation of enzymes caused by the influence of the solvent used and pH, and the steric hindrance of the compounds themselves, and highly efficient synthesis of BFC materials has not been realized. In order to solve these problems, this study aims to construct a completely new BFC material synthesis technology by utilizing the specificity of chemical reactions in an ultramicro-scale reaction field.

Outline

Force sensation is the sensation of being pushed strongly on a body and arms, or a reaction force perceived when pushing a hard object. Displaying force sensation can guide human behavior intuitively and improve a sense of immersion into a virtual reality space. However, a force display is typically large and heavy, it restricts the movement of users.
