Microfluidic Devices on Printed Circuit Board

Abstract

This chapter discusses a new approach for fabrication of microfluidic devices based on printed circuit board (PCB) technology. The chapter shortly describes the basic process steps in PCB fabrication considering the special needs of fluidic components to make it easier to understand the technological approach. Design, fabrication and characteristics of a number of sensors and actuators are presented. Results of active component such as diffuser/nozzle pumps, peristaltic pumps, check-valve pumps and sensors such as pressure sensors, flow sensors, bubble sensors, and pH sensors prove the feasibility of this new fabrication concept.
