Printable electronics are popular for it’s flexibility, lightweight, low cost and high performance. To manufacture printable electronics would require printing technique such as inkjet printing, screen printing, dispensing printing which requires high precision and control in order to print a good performance flexible electronics. Not only that, material used is also a huge factor affecting the production of printed electronics. The objective of the project is to investigate a suitable printing technique, dispensing printing which is able to print with accuracy, control and flexible in the type of surface it can be printed on. Using PEDOT:PSS (CLEVIOS S V4 STAB) material to be paired with dispensing printing technique to print out an actual all printed flexible electronics, organic electrochemical transistor (OECT). Further investigation on another potential material N-type BBL:PEI polymer ink shows that it has the potential to reach high conductivity that can match P-type conductive polymer in creating a device that can function as well as in electrical performance.
