Lab-on-Chip microfluidic systems require onboard functionalities such as fluid pumping, heating and fluorescent or chemical sensing. An approach is presented to realize these structures by inkjet printing of functional materials or material sandwiches and subsequent curing or sintering. In detail an electro-active polymer membrane pump with passive microstructured valves, an open loop controlled ohmic heater structure for maintaining discrete fluid temperatures and electrodes for free-flow isoelectric focusing along with fluorescent hydrogel pads for pH sensing are discussed that all together are printed onto the cover foil of a polymer based microfluidic chip platform at the size of a microscope slide.

  • For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.

    Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
