This video shows how to make an OFET in just 60 seconds in order to perform OFET mobility measurements or to act as a chemFET (also called a chemical field effect transistor or OFET sensor). By using Ossila pre-fabricated test chips, five individual OFETs can be fabricated on one substrate to allow for multiple mobility measurements quickly and easily. The OFETs are fabricated simply by spin coating the organic semiconductor onto the test chip and wiping the edges clean.
