Profile
Cellulose nanofiber materials, ISIR, Osaka University
Cellulose nanofibers with 4-20 nm width are bundles of cellulose microfibrils, which are frameworks of cell walls in all the plants. We have developed nano-fibrillation processes of bio-resources (wood, plants fibers, crabs, shrimps e.t.c.) and some advanced nanofiber materials with high optical transparency. Moreover, we have also improved their properties or processes to realize their applications in the electronic devices.

Measuring Brain Activity On The Go

Brain activity has traditionally been assessed using large and often expensive technology that has limited its use to specific clinical settings. Small wearable devices that can assess brain activity are hoped to improve the diagnosis and monitoring of brain diseases like dementia or depression.

3D Printed, Edible QR Codes

Researchers from Japan have developed a way to include an unobtrusive edible tag embedded inside food—in their original experiments, cookies—that can be read without having to first destroy the food. Another major advantage of their method, known as "interiqr," is that the tag doesn't change the outer appearance or taste of the food at all.

Improved Heat Dissipation in Thin Film Devices

The last few decades have witnessed a tremendous advance in electronics technology, with the development of devices that are thinner, lightweight, flexible, and robust. However, as the devices get thinner so does the space for accommodating the internal working components. This has created an issue of improper heat dissipation in thin-film devices, since conventional heat sink materials are bulky and cannot be integrated into them.

3D Printing Nickel Single Crystals Using Laser Additive Manufacturing

Researchers have succeeded in fabricating a nickel single crystal with only a very few crystalline defects by irradiating nickel powder with a large-radius, flat-top laser beam (i.e., a laser beam whose intensity is uniform across a cross-section of the beam). This technique may be used to fabricate a wide variety of single-crystalline materials, including heat-resistant materials for jet engines and gas turbines.

Seeing Photovoltaic Devices in a New Light

Photovoltaic which convert light energy into electronic power are important as renewable energy sources or as light/image sensors. Recent progress in thin film photovoltaic devices has attracted much attention owing to their low-cost process, flexibility, and light weight. However, although various photovoltaic devices have been reported so far, reversible and fast wavelength-dependent responses have not been previously observed.

Electronics Grow on Trees Thanks to Nanocellulose Paper Semiconductors

Semiconducting nanomaterials with 3D network structures have high surface areas and lots of pores that make them excellent for applications involving adsorbing, separating, and sensing. However, simultaneously controlling the electrical properties and creating useful micro- and macro-scale structures, while achieving excellent functionality and end-use versatility, remains challenging.

Toward Imperceptible Electronics That You Cannot See or Feel

Transparent electronics--such as head-up displays that allow pilots to read flight data while keeping their eyes ahead of them--improve safety and allow users to access data while in transit. For healthcare applications, the electronics need to not only be cheap and straightforward to fabricate, but also sufficiently flexible to conform to skin. Silver nanowire networks meet these criteria. However, current methods of development create random nanowire alignment that's insufficient for advanced applications.

Robot-ants that can jump, communicate and work together

A team of researchers has developed tiny 10-gram robots that are inspired by ants: they can communicate with each other, assign roles among themselves and complete complex tasks together. These reconfigurable robots are simple in structure, yet they can jump and crawl to explore uneven surfaces.
