Flexible Electronic Devices

The development of processing methods for flexible electronic devices is seen as an enabling technology for the creation of a new array of semiconductor products. These devices have the potential be low cost, disposable, and can be applied to deformable or non-planar surfaces. While much effort has been put into the development of amorphous silicon and organic semiconductor technology for flexible devices, semiconductor nanomaterials are of interest due to their inherently flexibility, high transport mobilities, and their unique optoelectronic and piezoelectric properties. However, the synthesis of these materials directly onto polymer substrates is not feasible due to the high temperatures or harsh chemical environments under which they are synthesized. This challenge has limited the development of flexible electronics with semiconductor nanomaterial building blocks. A number of techniques which address the manufacturing concerns include solution based processing [1,2] as well as dry transfer techniques [3–5]. In general, dry transfer printing methods carry advantages over solution based processing as the need to address substrate-fluid compatibility is mitigated.

Carbon Nanotube Yarns

In this work, the morphology and electrocatalytic features of carbon nanotube yarns at the structural level allow for enhanced photoconversion efficiency. The energy conversion of electron-hole pairs within the carbon nanotube yarn (CNY) due to the functionalization with nanostructured photoactive TiO2 phases is remarkable. A well oriented anatase TiO2 thin layer (approximately 100 nm) forms at the interfaces of CNY and TiO2 mesoporous film when the sample is precoated and annealed at 350°C. Field Emission Scanning Electron Microscopy (FESEM) images show the integrity and homogeneity of the TiO2 surface, which is indicative of the overall durability of the CNY-based dye sensitized solar cell (DSSC); Coating TiO2 on self-aligned carbon nanotube yarns provides several benefits from their high chemical stability, excellent functionality, nontoxicity and relatively low cost. The maximum photon to current conversion efficiency (ηAM1.5) achieved was 3.1%.

Abstract Recently, the three-dimensional (3D) printing technique has attracted much attention for creating objects of arbitrary shape and manufacturing. For the first time, in this work, we present the fabrication of an inkjet printed low-cost 3D temperature sensor on a 3D-shaped thermoplastic substrate suitable for packaging, flexible electronics, and other printed applications. The design, fabrication, and testing of a 3D printed temperature sensor are presented. The sensor pattern is designed using a computer-aided design program and fabricated by drop-on-demand inkjet printing using a magnetostrictive inkjet printhead at room temperature. The sensor pattern is printed using commercially available conductive silver nanoparticle ink. A moving speed of 90 mm/min is chosen to print the sensor pattern. The inkjet printed temperature sensor is demonstrated, and it is characterized by good electrical properties, exhibiting good sensitivity and linearity. The results indicate that 3D inkjet printing technology may have great potential for applications in sensor fabrication.

Carbon membranes have high adsorption capacitiy with respect to its incredible properties such as unique structural, electronic, optoelectronic, semiconductor, mechanical, chemical and physical. Carbon nanotube (CNT) membranes because of its high permeance have been recently developed.Great attention has been currently paid to the field of fabrication methods capable of producing uniform, well-aligned and monodispersed CNT array. Current research concerns with fabrication of vertically aligned CNT membrane in order to remove heavy metal ion presents in waste water. For this purpose, CNTs are vertically grown up through the holes of anodic aluminium oxide (AAO); as a template, by chemical vapor deposition (CVD) of acetylene gas.In this work a few heavy metals such as Pb (II), Cu (II) and Cd (II) has been examined for checking the perfomance of membrane in aqueous solution. The morphological properties of the aligned CNT membrane were investigated with scanning electron microscopy (SEM). The method has simple technology, low cost, and easy reproduction.
