A low cost method of fabricating thick film microelectrodes on plastic substrate for producing integrated plastic biochips is introduced in this paper. Microelectrodes for pumping liquid in a PCR plastic biochip were successfully fabricated using a metal stamp and commercially available Au films. Testing results show that the microelectrode produced with the metal stamp is more reliable and can last longer than those fabricated with sputtering techniques. The fabrication method demonstrated in this paper provides a new low cost technology that is suitable for mass production of thick-film microelectrodes of high electrical conductivity on plastic biochips.
