Printing techniques have been extensively used in the fabrication of organic electronic devices, such as light-emitting diodes and display backplanes. These techniques, in particular inkjet printing, are being employed for the localized dispensing of solutions containing biological molecules and cells, leading to the fabrication of bio-functional microarrays and biosensors. Here, we report the ...

A low-power, wide-dynamic-range integrated humidity sensing chip is implemented using a printable polymer sensing material with an on-chip pulse-width-modulation interface circuit. By using the inkjet printing technique, poly(3,4-ethylene-dioxythiophene)/polystyrene sulfonate that has humidity sensing features can be printed onto the top metal layer of a 0.35 μm CMOS IC. The developed printing-...

Inkjet 3D printing is with success used for preparation microfluidics devices as a microfluidic chips for DNA separation. Utilized this technic help us to prepare a chip in shorter time and cheaper, but length of microchannel are limited by possibility of support material removing. One of the Solution for solve this limitations is divide a microfluidics chips for modules and printing them separ...

A combination of surface energy-guided blade coating and inkjet printing is used to fabricate an all-printed high performance, high yield, and low variability organic thin film transistor (OTFT) array on a plastic substrate. Functional inks and printing processes were optimized to yield self-assembled homogenous thin films in every layer of the OTFT stack. Specifically, we investigated the effe...

Biochips are composed of arrays micropatterns enabling the optical detection target analytes. Inkjet printing, complementary to commercially available micro- and nanospotters, is a contactless versatile micropatterning method. Surprisingly, inkjet printing molecularly imprinted polymers (MIPs), also known as biomimetic synthetic antibodies, has not been demonstrated yet. In this work, core–shel...

and Introduction: Ink-jet printing allows for cost efficient roll-to-roll manufacture of thin-film transistors (TFTs) over large areas, enabling next-generation transparent displays, touch panels, opto-electronics, and radio frequency identification [1-4]. TFT conductance and cutoff frequency scale inversely with gate length. However sub-micron gate lengths are incompatible with traditional pri...

This article presents a digital fabrication platform for depositing solution-based natural stimuli-responsive material on a thin flat substrate to create hygromorphic biohybrid films. Bacillus subtilis bacterial spores are deposited in the printing process. The hardware system consists of a progressive cavity pump fluidic dispenser, a numerical control gantry, a cooling fan, a heating bed, an a...
