Digital Fabrication of UHF Electromagnetic Structures, EPSRC-funded project in collaboration with the University of Kent. This is a cross disciplinary proposal aimed at applying expertise in chemistry to the generation of an innovative manufacturing technique relevant to 2 key areas:
RFID tags for mounting directly on human skin and
mobile and wireless communication in high-tech buildings.
Inkjet printing will enable short run RFID tag tattoo transfers with and without chips and Frequency Selective Screens to be developed in a cost effective and scalable fashion. Both of the aspects of antenna technology figuring in this project impinge on matters of security in the electronics world. The research is a collaboration between the School of EDA at Kent, OMIC at the University of Manchester, Great Ormond St Hospital and DSTL.
Formulation and Characterization of Inkjet Printing Fluid, in collaboration with Domino UK Ltd.
Inkjet Printing Biosensors:We are studying the use of inkjet printers to fabricate protein based biosensors. There are concerns that the high shear rates during droplet ejection and impact may influence protein shape and hence enzymatic performance post-printing; a range of proteins are under study. We are also investigating printable electrodes and protein/electrode interactions.
Direct Write Processes: We are working with colleagues in industry to develop inkjet printing and other direct write methods to produce functional devices on existing structures. We are studying metallisation through novel printable silver precursors and studying ink/surface interactions.
Inkjet Printing Cells and Biomaterials: We are developing the use of inkjet printers to co-deposit living cells with biomaterials to generate hybrid cell-containing structures with potential applications in tissue engineering and cell-based sensors. We have studied the response of a range of cell types to the stresses of printing and are now studying the patterning of structured surfaces with controllable cell-adhesion. We are also exploring novel methods for the delivery of hydrogel materials.
