HQ Country
Okayama University is one of the national universities in Japan. Our research group focuses on the synthesis of the ambient conductive metal nanoink. The ambient conductive metal nanoink fabricates the electroconductive printed metallic film without post treatment such as annealing.
The resistivity is as low as 8 x 10^-5 ohmcm Just after printing and drying under ambient condition.

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.

Thin film to stimulate retinal tissue

Using electric signals to stimulate tissues is the basis of several medical devices such as pacemakers for the heart or neurostimulators used for patients suffering from epileptic fits. A research team has developed a photoelectric dye-coupled thin film device that generates electric potential changes when exposed to light. In their latest study, the research team reveals the ability of this device in stimulating degenerated retinal tissues.

Colloidal Ink Co., Ltd

Colloidal Ink is a recently formed spin-out from Okayama University. IDTechEx awarded Colloidal Ink the best Technical Development Materials Award at its Printed Electronics Conference (Europe) 2013. Colloidal Ink has developed a patented and promising formulation technology which enables rapid sintering of conductive nano inks at room temperature. They have so far demonstrated their conductive paints using gold nanoparticles and are also developing nano silver in their pipeline. Their samples today are conductive paints and the formulation will have to be modified to create screen- or inkjet- printable inks. Colloidal Ink is now in the sample distribution mode.
