Abstract:This article describes direct laser printing of thin-film polymer onto rigid substrates for use as an etch mask or liftoff layer in patterning on-chip electrical components. Using this technique, the authors fabricated planar spiral inductors of 12×12mm2 with 2.5–5.5 turns producing series inductance Ls=80–180nH as well as planar interdigitated capacitors of 10×10mm2 with two to nine fingers producing series capacitance Cs=100–1600nF. This technique is a low cost, low temperature, rapid turn around, maskless, … Show more
“…Passive fluidic micromixers have been printed onto plastic transparencies using both laser printing [4] and wax transfer printing [5]. Inkjet printing has been used to directly pattern and deposit conductors, dielectrics, and piezoelectric materials for MEMS device fabrication [6] The fabrication technique discussed here builds on work using laser print patterned polystyrene MEMS devices [7], laser-printed layers for etch masking [8] and fabrication using micromilled plastics [9]. These…”
This paper describes the fabrication and testing of a one-axis polymer-based capacitive accelerometer made using a reel-to-reel/roll-to-roll compatible, printing-based process. The accelerometer is a suspended parallel-plate sense capacitor made from a laser-printed polystyrene composite material on a flexible plastic substrate. With a simple analog voltage readout circuit, device sensitivity is 58mV/g with +/-1.5g range. This device demonstrates fabrication of ultra-low-cost MEMS sensors on flexible polymer substrates.
