Screen printing is a potential technique for mass-production of printed electronics; however, improvement in printing resolution is needed for high integration and performance. In this study, screen printing of highly loaded silver ink (77 wt %) on polyimide films is studied using fine-scale silicon stencils with openings ranging from 5 to 50 μm wide. This approach enables printing of high-reso...
We demonstrate the integration of subwavelength moth-eye and Al2O3 nanoisland structures fabricated on polymer packaging sheets and the surface of conventional Al2O3/TiO2 bilayer antireflection coatings, respectively, with epitaxial lift-off single-junction GaAs solar cells. The mechanically flexible cell structure with the integrated optical nanostructures shows substantially improved photovol...
The characteristics of hole-assisted fiber (HAF) are investigated both numerically and experimentally in terms of its applicability as a bending-loss insensitive fiber (BIF). We show that HAF with the desired mode-field diameter (MFD), bending-loss and cutoff wavelength characteristics can be roughly designed by taking a few specific structural parameters into consideration. We also show that a...
In this paper, we consider the problem of computing a minimum bending energy path (or MinBEP) in a simple corridor. Given a simple 2D corridor C bounded by straight line segments and arcs of radius 2r, the MinBEP problem is to compute a path P inside C and crossing two pre-specified points s and t located at each end of C so that the bending energy of P is minimized. For this problem, we first ...
We present a modular high-vacuum setup for the electrical characterization of single molecules down to liquid helium temperatures. The experimental design is based on microfabricated mechanically controllable break junctions, which offer control over the distance of two electrodes via the bending of a flexible substrate. The actuator part of the setup is divided into two stages. The slow stage ...
A flexible hybrid heterojunction PbS colloidal quantum dot solar cell, where the photoactive layers are deposited using a solution processed fabrication approach under ambient condition and at room temperature is presented. The bending stability of the obtained solar cell is evaluated. The results show that the solar cell exhibits high bending stability and even under the bent state the cell al...
In this study, the Taguchi method is used to find the optimal process parameters for an injection moulding machine that was used to produce a consumer product (plastic tray) from polypropylene (PP) plastic material. An orthogonal array (OA), main effect, signal-to-noise (S/N) ratio, and analysis of variance (ANOVA) were employed to investigate the bending characteristics of the tray under a con...
با توجه به پیشرفت روز افزون طراحی براساس عملکرد با استفاده از تغییر مکان مطالعاتی بر روی سازه های مختلف انجام شده که بیشتر این مطالعات بر روی سازه های متقارن در پلان بوده است . در این تحقیق سعی شده است که سازه های خمشی با پلان نا متقارن طراحی شده بر اساس آئین نامه ایران را مورد بررسی قرار داده و برای نشان دادن تاثیر خروج از مرکزیت از انتقال مرکز جرم به میزان 10و 15 درصد بعد ساختمان استفاده شده ...
Electro active polymers (EAPs) exhibit large electrically induced strains (bending or stretching) with electrical stimuli. EAPs are utilized as actuators in micro gripper and micromanipulator in micro robotics activities. Remote center compliance (RCC) based micro gripper is developed to facilitate insertion of peg-in-hole (PIH) for micro assembly operations. An effect of RCC compliance during ...
Feature descriptors have enabled feature matching under varying imaging conditions, while mostly being backed by experimental evidence. In addition to imposing some restrictions in imaging conditions needed to ensure matching, extending the existing descriptors is not straightforward due to the lack of sound mathematical bases. In this work, by using a surface bending versus shape histogram bas...
