Point-of-Care (PoC) diagnostic devices, such as lateral flow tests, are often used in low and middle-income countries (LMIC) for low-cost disease detection. Most commercial lateral flow tests use colorimetric detection on a nitrocellulose substrate. In this paper, we present a multistep, fluorescence-based assay detection system, which can detect antibodies in plasma to recombinant protein. Fluorescence-based...
This paper presents a design of a Triband microstrip antenna for 2.4 GHz, 3.5 GHz and 5.7 GHz applied a WBAN (Wireless Body Area Network). The proposed antenna with three substrates types consists of L-shaped slots have been determined based on the frequency bands. For the integration of these techniques three frequency bands consisting of the ISM band 2.4 GHz and 5.7 GHz, and 3.5 GHz band UWB respectively...
In this study, a high-efficiency and low dark current thin-film crystalline selenium (c-Se)/gallium oxide (Ga2O3) heterojunction photodiode is demonstrated via improving the deposition conditions for the tellurium nucleation layer that prevents the peeling of the selenium film during annealing. The highly (100)-oriented polycrystalline selenium film is grown by employing a thin tellurium (Te) nucleation...
For the highly-sensitive optical MCLW biosensor, the stability of the acrylate-based hydrogel waveguiding sensing layer deposited onto the Ti (titanium)-coated glass substrate depends on the quality of surface modification between the interfaces. This study demonstrates an optimised silanization technique to form covalent bonds across the interface between the modified Ti-coated glass substrate and...
“Acoustic angiography” is a super-harmonic contrast imaging technique, which is based on the fact that when excited with a moderate acoustic pressure near their resonance (2–4 MHz; around MI of 0.5–0.7) ultrasound contrast agents produce broadband content which extends well past 15 MHz. By detecting the higher order harmonic energy while transmitting at a low fundamental frequency, exquisite resolution...
Multilayered structures with LT plates bonded to silicon or glass substrates via AlN, isotropic SiO2 or their combinations, were theoretically investigated as potential materials for resonators with high Q-factors required for the 5th generation of mobile communication systems. Characteristics of SH-waves propagating under Al grating in such structures, including electromechanical coupling and propagation...
SH-polarized plate modes propagating in thin membranes of 42°-48°LT cuts can combine high Q-factors with electromechanical coupling up to 20% and zero TCF. For high frequency applications the main challenge is fabrication of thin membranes, less than 1 micron at GHz frequencies. Thin LT plates solidly mounted on supporting substrates can help avoid fabrication of fragile membranes. The nature of plate...
This work introduces a super-hydrophobic hybrid thin film which shows the capability of thermal management. The hybrid thin film was obtained by sputtering a fluorocarbon layer on a glass substrate that has been pre-deposited by a layer of soot. Multiple characterization methods, e.g. Energy Dispersive Spectrometer (EDS), Static Contact Angle Measurement and Field Emission Scanning Electron Microscopy...
We have developed highly transparent color liquid crystal display (LCD) using newly developed scattering-type liquid crystal, which shows transparent state when voltage is not applied, with field sequential color (FSC) driving method without employing color filter and polarizer. Furthermore the light is directly introduced to the panel glass substrates from the edge of the substrates (not from back...
Four-terminal (4T) polycrystalline-germanium (poly-Ge) thin-film transistors (TFTs) are fabricated at 300 °C by metal induced crystallization (MIC) using copper (Cu) on a glass substrate. We observed variations in the performance for top gate (TG) and bottom gate (BG) drives, although the gate stacks of both drives are same. This difference results from the quality of the poly-Ge/BG SiO2 interface,...
InGaZnO (IGZO) nanowires were synthesized via bimetal-catalyzed VLS growth process from amorphous InGaZnO thin film. Amorphous IGZO thin film was initially deposited, followed by the thin film deposition of metal catalysts (Mo and Au). Annealing was then performed at 700°C under pure N2 atmosphere under three different time periods (0.5 h, 1 h and 2 h) to observe the effect of annealing time on the...
Color temperature of electroluminescence from white light-emitting electrochemical cells can be adjusted by locally laser-scanned thermal annealing on a semi-continuous thin Ag film embedded between indium tin oxide anode and glass substrate. The proposed technique offers programmable versatility to control white electroluminescence and is compatible with display manufacturing technologies.
High performance and low power dissipation low-temperature (LT) polycrystalline-silicon (poly-Si) thin-film transistors (TFTs) are indispensable for integrating circuits on a glass substrats. To control the threshold voltage of LT poly-Si TFTs, we employed four-tsrminal self-aligned planar embedded metal double-gate LT poly-Si TFTs using high quality lateral large grained thin poly-Si films. Successful...
We present a transimpedance amplifier (TIA) based on a low temperature polysilicon (LTPS) process, which is operated in a rïactive atmosphere of alkali vapor contained in a glass cell. We successfully encapsulated the electronics and present a sealing method for the glass cell, which is compatible with the employed LTPS process and shows long term leak tightness in the ultra high vacuum regime. The...
Ultra-thin flexible glass provides all the benefits of glass — thermo-mechanical stability at high temperature, transparency and the best barrier property in a transparent material, while capable of using R2R processing and deliver products that can be flexible. Corning® Willow® Glass is 100–200 μm thick glass that is flexible and is used in a roll-to-roll (R2R) process. In this paper we will discuss...
Influenced by the assembly accuracy of microwave modules, a gap often locates between two different components, such as metal cavity and LTCC substrate, which induces the discontinuity of microwave ground and resonation in millimeter wave band. These influences can be ameliorated by bonding a flexible transmission line between the two different materials, thus the voltage standing wave ratio and microwave...

We have demonstrated a new composite thin film for encapsulation consisting of polydimethylsiloxane (PDMS) and graphene. Graphene is a kind of hydrophobic material, causing that moisture could hardly penetrate into the surface of graphene. Graphene is usually fabricated by the method of Chemical Vapor Deposition (CVD). The atomic distance of graphene is very small; thus the water vapor channel from...

In this work, we present a novel wafer-level fabrication method of RF interposer applied in the integration of band pass filter in the frequency range of X band. In order to reduce the insertion loss caused by parasitic effects in the substrate, a special designed TSVs transmission structure (a core TSV and six shielding...
