It makes use of various printing techniques, including inkjet printing, screen printing, and offset printing, to manufacture electronic components on flexible or even stretchable substrates. The major problems for those printed devices are either function deterioration or structural instability of the printed patterns after numerous bending and stretching cycles. Thus, the current key technological challenges to those printed electronics are (i) formulation of functional inks and (ii) adhesion and stability of printed patterns. The main purposes of this project are to utilize chemical or physical means to formulate high-performance ink and apply various types of printing technology to produce stretchable electronic devices. In this project, we expect to accomplish the following: 1 Manufacture highly stretchable conductive metal tracks on plastic substrates. 2 Develop printing process for patterned stretchable tracks. 3 Formulate metal oxide or polymer inks for highly stretchable electronic devices, such as UV photo detectors or polymer LED. 4 Investigate the compatibility between conductive tracks and functional layers. 5 Integrate and optimize printing processes for stretchable electronics. In summary, we will apply printing technologies to manufacture stretchable electronics for affordable devices with great functions and high accuracies. We believe that the fundamental understandings from this research project will greatly help technological advances of this important technology in the next decade. The accumulated knowledge and experiences of those key technologies will also strengthen the competitiveness of printed electronic industry in Taiwan.印刷電子Printed Electronics
