Printing colour pictures in a TEX document needs a driver program that is able to exploit the capabilities of a colour device. The driver must separate the colours of the picture into the basic colours used by the colour model supported by the output device. This was the purpose to develop the dvi djc-drivers for the Hewlett Packard inkjet printers and to upgrade BMZFONT to version 3.0. The sol...

The modification of silver screen-printed electrodes with a dodecyl benzenesulphonic acid and KCl solution was performed by inkjet printing. Scanning Electron Microscopy was performed to characterize the electrode surfaces. Electrochemical reduction of H2O2 was studied and compared to electrodes modified by dip-coating. Analytical parameters of the allprinted electrode such as LOD, sensitivity ...

Here we present a simple and low-cost production method to generate paper-based microfluidic devices with wax for portable bioassay. The wax patterning method we introduced here included three different ways: (i) painting with a wax pen, (ii) printing with an inkjet printer followed by painting with a wax pen, (iii) printing by a wax printer directly. The whole process was easy to operate and c...

Scalable circuits of organic logic and memory are realized using all-additive printing processes. A 3-bit organic complementary decoder is fabricated and used to read and write non-volatile, rewritable ferroelectric memory. The decoder-memory array is patterned by inkjet and gravure printing on flexible plastics. Simulation models for the organic transistors are developed, enabling circuit desi...

We report on a hybrid manufacturing approach for organic electrochemical transistors (OECTs) on flexible substrates. The technology is based on conventional and digital printing (screen and inkjet printing), laser processing, and post-press technologies. A careful selection of the conductive, dielectric and semiconductor materials with respect to their optical properties enables a self-aligning...

The development of printed electronics will require the ability to deposit a wide range of nanomaterials using printing techniques. Here we demonstrate the controlled deposition of networks of silver nanowires in well-defined patterns by inkjet printing from an optimized isopropyl alcohol-diethylene glycol dispersion. We find that great care must be taken while producing the ink and during solv...

Structuring SU-8 based superparamagnetic polymer composite (SPMPC) containing Fe3O4 nanoparticles by photolithography is limited in thickness due to light absorption by the nanoparticles. Hence, obtaining thicker structures requires alternative processing techniques. This paper presents a method based on inkjet printing and thermal curing for the fabrication of much thicker hemispherical micros...

We introduce a new approach to design and fabrication of mechatronic systems called flexonics. Flexonics integrates structural, mechanical and electronic elements based on 3D printing techniques, in particular inkjet printing. This paper outlines some principles for flexonic design, which is based on flexion rather than sliding or rolling motion as in traditional mechanics. It describes our pre...

Writing process patterns directly on a substrate with small liquid droplets generated by Drop-On-Demand (DOD) inkjet devices offers a low cost, non-contact, low temperature, flexible, and data driven patterning approach. Existing inkjet printheads have a limited number of inkjet devices, which generate droplets on the scale of tens of microns. In our research, we have developed a monolithic ink...
