  • Flexible Devices with Printed Organic and Nanoparticle Materials

    We have developed flexible electronic devices on ultrathin (< 3 µm) plastic films by employing advanced printing technologies together with organic semiconductors, ferroelectric polymers, and metal nanoparticle inks. Our objective is to realize patch-type healthcare devices using the ultra-flexible sensor devices.    top-leftto-bottom
  • Development of the OFET-Based Biosensors

    We have developed printed OFET-based biosensors that are fully flexible, and are currently striving to apply these sensors in the non-invasive detection healthcare biomarkers in externally secreted bodily fluids including sweat and saliva.    top-leftto-bottom
  • Flexible and Stretchable Printed Physical Sensors

    We are developing flexible or stretchable physical sensors that employ ferroelectric polymers and stretchable paste inks applied using conventional printing methods. Our aim to utilize these devices in robot skins, healthcare, tactile sensors and other novel applications.    top-leftto-bottom
  • Flexible Hybrid Electronics

    Organic thermal sensors and stacked interconnects are printed on plastic film substrates using conventional screen printing, and to which thin, small Si-LSI chips are mounted. This hybrid sensor combines the flexibility of organic electronics with the highly functional of silicon electronics. Using these devices, we have succeeded in measuring skin temperature and monitoring the temperature of commercial products, while wirelessly transmitting the data.    top-leftto-bottom

  • Development of the Metal Nanoparticle Ink

    We are developing metal nanoparticle ink that can be sintered at low-temperature to create high-performance printed TFT devices. We achieved a reduction of the energy barrier between semiconductor and electrodes by improving the nanoparticle design and ink formulation technology.    top-leftto-bottom
  • Development of the Large Area Printing Processes

    We have developed the roll-to-roll inkjet printing process technology that can be applied to the fabrication of large-area, high-definition electronic circuits. With this technology, TFT arrays and sensor devices can be continuously fabricated directly on the wide-format film rolls.    top-leftto-bottom
