“…[ 118 ] Due to the mechanical instability of the soft polymeric stamp, the dimensions of the channels in MIMIC are typically limited to about a few hundred nanometers. [ 119 ] A similar process of patterning a precursor material with MIMIC on a fl exible substrate, and transition into a conductive material after stamp removal, has been reported for graphene oxide. [ 120 ] With a hard PDMS stamp, centimeter-long and large-area 10 μ m wide, ultrathin (1-3 nm) microwires of reduced graphene oxide fl akes (500 nm to 1.5 μ m) have been patterned by MIMIC of graphene oxide in aqueous solution on 3-aminopropyl-triethoxysilane (APTES)-treated substrates (SiO 2 wafer, quartz, and PET), followed by a chemical reduction with hydrazine vapor.…”

In this report, the development of conventional, mass-printing strategies into high-resolution, alternative patterning techniques is reviewed with the focus on large-area patterning of flexible thin-film transistors (TFTs) for display applications. In the first part, conventional and digital printing techniques are introduced and categorized as far as their development is relevant for this application area. The limitations of conventional printing guides the reader to the second part of the progress report: alternative-lithographic patterning on low-cost flexible foils for the fabrication of flexible TFTs. Soft and nanoimprint lithography-based patterning techniques and their limitations are surveyed with respect to patterning on low-cost flexible foils. These show a shift from fabricating simple microlense structures to more complicated, high-resolution electronic devices. The development of alternative, low-temperature processable materials and the introduction of high-resolution patterning strategies will lead to the low-cost, self-aligned fabrication of flexible displays and solar cells from cheaper but better performing organic materials.

“…In this context, it is important to push the limit of resolution achieved by MIMIC in order to find its niche in next-generation lithography techniques. For improving the resolution of MIMIC, nanomolding in capillaries was recently introduced using composite PDMS stamps with sub-100 nm channels [47]. It is indeed attractive and cost effective only if the methodology of MIMIC could be somehow modified to produce nanosized features using the microchannels.…”

“…we proposed a strategy to combine the micro/nano confinement with the materials doping to simultaneously optimize the response time and sensitivity of PEDOT: PSS based resistortype temperature sensor. Low dimension PEDOT: PSS wires from a few micrometers down to sub-100 nm in diameters were fabricated using a low-cost micro/nanoscale printing approach (Gates et al, 2005;Massi et al, 2006;Duan et al, 2010;Tang et al, 2019). Their sensitivity and response time to temperature were compared (Scheme 1).…”

Low dimension poly(3,4-ethylenedioxythiophene) poly (styrenesulfonate) (PEDOT: PSS) has been applied as resistor-type devices for temperature sensing applications. However, their response speed and thermal sensitivity is still not good enough for practical application. In this work, we proposed a new strategy to improve the thermal sensing performance of PEDOT: PSS by combined micro/nano confinement and materials doping. The dimension effect is carefully studied by fabricating different sized micro/nanowires through a low-cost printing approach. It was found that response speed can be regulated by adjusting the surface/volume (S/V) ratio of PEDOT: PSS. The fastest response (<3.5 s) was achieved by using nanowires with a maximum S/V ratio. Besides, by doping PEDOT: PSS nanowires with Graphene oxide (GO), its thermo-sensitivity can be maximized at specific doping ratio. The optimized nanowires-based temperature sensor was further integrated as a flexible epidermal electronic system (FEES) by connecting with wireless communication components. Benefited by its flexibility, fast and sensitive response, the FEES was demonstrated as a facile tool for different mobile healthcare applications.
