Organic electronic devices fabricated by entirely wet processes using organic semiconductors, insulators, metal nanoparticles, etc., have been attracting much attention. In particular, by utilizing printing techniques on plastic substrates, flexible electronic devices of large area and low-cost will be attained. However, conventional printing techniques such as flexo printing, screen printing a...

Conductive flexible hydrogel composites were printed on paper substrates using a functional ink, whichwas designed and formulated for screen-printing. The inkswere prepared using abundant and eco-friendlymaterials by blending carbon fibers into thematrix of a water-soluble cellulose derivative, carboxymethyl cellulose. For an optimal concentration of carbon fibers (10wt.%), the printed patterns...

The paper reports on temperature behavior of strain sensitivity of recently introduced screen printing technology facilitating the realization of silver and carbon black piezoresistors embedded in organic coatings. Piezoresistive layers were prepared by screen printing directly on the top of the organic coating. Since no glue or carrying substrates are between the sensitive element and the devi...

Flexible transistor active matrix array is fabricated on PEN substrate using all screen-printed gate, source and drain electrodes. Parylene-C and DNTT act as gate dielectric layer and semiconductor, respectively. The transistor possesses high mobility (0.33 cm 2 V -1 s -1 ), large on/off ratio (> 10 6 ) and low leakage current (~10 pA). Active matrix array consists of 10×10 transistors were dem...

This paper reports the fabrication and testing of Bismuth Tellurium (Bi2Te3) – Antimony Tellurium (Sb2Te3) based thermocouples using screen printing technology. In this study, screen printable thermoelectric pastes were developed and the transport properties of cured material were measured. The dimension of each planer thermoleg is 39.3 mm × 3 mm with a thickness of 67 μm for Bi2Te3 leg and 62 ...

A Prussian blue (PB) biosensor chip with the nanocubic crystals was fabricated in batch by a screen printing technique for the general detection of various physiological substances. Through a low-speed chemical synthesis approach, the nanostructure of PB slurry was well controlled to be a 100 nm nanocube by the synthesis temperature and reactant concentration. Then, PB slurry was screen-printed...
