  • Flexible Devices with Printed Organic and Nanoparticle Materials

    We have developed electronic devices on ultrathin (< 3 µm) plastic films by printing organic semiconductors, ferroelectric polymers and metal nanoparticle inks. We will realize patch-type healthcare devices using the ultra-flexible devices.

  • Development of the OFET-Based Biosensor

    We have been developing totally flexible, printed OFET-based biosensors. Now we are challenging to apply these sensors for non-invasive healthcare detecting biomarkers in externally secreted bodily fluids including sweat and saliva.
