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 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
