This paper used COMSOL Multiphysics software to simulate and design two kinds of new touch panels with chain and mountain-shaped ITO electrodes, respectively. These two touch panel electrodes were both designed using parallel and vertical capacitance configurations. Compared with traditional common rectangular and diamond-shaped electrodes, it was found in simulation results that parallel and vertical capacitive gains for chain and mountain-shaped electrodes were 30% and 6%, respectively, higher than those for traditional rectangular and diamond-shaped ones. In addition, when the ratio of glass thickness (H) to indium tin oxide (ITO) electrode thickness (h) was larger, the corresponding capacitive gain was smaller.

The indium tin oxide (ITO) has been widely applied in light emitting diodes (LEDs) as the transparent current spreading layer. In this work, the performance of GaN-based blue light LEDs with nanopatterned ITO electrode is investigated. Periodic nanopillar ITO arrays are fabricated by inductive coupled plasma etching with the mask of polystyrene nanosphere. The light extraction efficiency (LEE) of LEDs can be improved by nanopatterned ITO ohmic contacts. The light output intensity of the fabricated LEDs with nanopatterned ITO electrode is 17% higher than that of the conventional LEDs at an injection current of 100 mA. Three-dimensional finite difference time domain simulation matches well with the experimental result. This method may serve as a practical approach to improving the LEE of the LEDs.

The improved binding ability of graphene–nanoparticle composites to proteins or molecules can be utilized to develop new cell-based assays. In this study, we fabricated reduced graphene oxide–gold nanoparticles (rGO-AuNP) electrodeposited onto a transparent indium tin oxide (ITO) electrode and investigated the feasibility of the electrochemical impedance monitoring of cell growth. The electrodeposition of rGO–AuNP on the ITO was optically and electrochemically characterized in comparison to bare, rGO-, and AuNP-deposited electrodes. The cell growth on the rGO–AuNP/ITO electrode was analyzed via electrochemical impedance measurement together with the microscopic observation of HEK293 cells transfected with a green fluorescent protein expression vector. The results showed that rGO–AuNP was biocompatible and induced an increase in cell adherence to the electrode when compared to the bare, AuNP-, or rGO-deposited ITO electrode. At 54 h cultivation, the average and standard deviation of the saturated normalized impedance magnitude of the rGO–AuNP/ITO electrode was 3.44 ± 0.16, while the value of the bare, AuNP-, and rGO-deposited ITO electrode was 2.48 ± 0.15, 2.61 ± 0.18, and 3.01 ± 0.25, respectively. The higher saturated value of the cell impedance indicates that the impedimetric cell-based assay has a broader measurement range. Thus, the rGO–AuNP/ITO electrode can be utilized for label-free and real-time impedimetric cell-based assays with wider dynamic range.

A novel electro-codeposited film was homogeneously obtained on an indium tin oxide (ITO)-coated glass electrode by cathodic polarization of a solution of 2,9,16,23-tetracarboxyphthalocyaninatomagnesium(II) ( Mg II taPc ), N,N′-4-hydroxyphenyl-3,4,9,10-perylenetetra-carboxylic-diimide (4-hph-PTC) and ZnCl 2 as supporting electrolyte in N,N-dimethylformamide (DMF). The cyclic voltammogram for the codeposited film showed a reduction at −0.8 V vs SCE which was assigned to the reduction of Mg II taPc and one at −1.5 V vs SCE which was assigned to the reduction of 4-hph-PTC. A device based on the codeposited film was prepared by the formation of an aluminum electrode on the codeposited film. The device exhibited rectification and photoconduction. The results suggest that the codeposited film forms a number of p-n junction interfaces which are distributed on the ITO electrode.

A novel transparent and nanostructured ion-sensitive electrode based on indium tin oxide (ITO) coated with cobaltbis(dicarbollide)-doped poly(pyrrole) (PPy) is presented in this work. This metallacarborane-doped PPy was used as conducting polymer due to its high stability and chemical resistance. The ion-sensitive electrode was coupled to a miniaturized and low-cost potentiostat, in a final autonomous kit for potentiometric determination of pH. Qualitative calibration of the system revealed Nernstian behavior, resulting promising for novel point-of-care biomedical applications.
