Quantitative Analysis to the Impacts of IMU Quality in GPS/INS Deep IntegrationMicromachines - Tập 6 Số 8 - Trang 1082-1099
Xiaoji Niu, Yalong Ban, Quan Zhang, Tisheng Zhang, Hongping Zhang, Jingnan Liu
In the Global Positioning System (GPS)/Inertial Navigation System (INS) deep
integration system, the pure negative effect of the INS aiding is mainly the INS
navigation error that is independent with the motion dynamics, which determine
whether the INS aiding is worthy. This paper quantitatively assesses the
negative effects of the inertial aiding information from different grades of INS

Liquid Cladding Mediated Optical Fiber Sensors for Copper Ion DetectionMicromachines - Tập 9 Số 9 - Trang 471
Vien Thi Tran, Nhu Hoa Thi Tran, Than Thi Nguyen, Won Jung Yoon, Heongkyu Ju
We present a label-free optical fiber based sensor device to detect copper ions
(Cu2+) in water. A multimode optical fiber, with its polymer cladding removed
along a 1-cm length, is used for the optical sensor head, where the injected
Cu2+ in the liquid phase acts as a liquid cladding for the optical mode. The
various Cu2+ concentrations modulate the numerical aperture (NA) of the liquid
cladding ... hiện toàn bộ
Fabrication of ZnO@Ag@Ag3PO4 Ternary Heterojunction: Superhydrophilic Properties, Antireflection and Photocatalytic PropertiesMicromachines - Tập 11 Số 3 - Trang 309
Huan Huan, Gongfa Li, Yijun Tang, Xin Li, Zao Yi, Xiang Gao, Xifang Chen, Jian Chen, Pinghui Wu
A ZnO seed layer was formed on the fluorine-doped tin oxide substrate by
magnetron sputtering, and then a ZnO nanorod was grown on the ZnO seed layer by
a hydrothermal method. Next, we prepared a single-crystal Ag seed layer by
magnetron sputtering to form a ZnO@Ag composite heterostructure. Finally, Ag3PO4
crystals were grown on the Ag seed layer by a stepwise deposition method to
obtain a ZnO@Ag... hiện toàn bộ
Study of Inkjet-Printed Silver Films Based on Nanoparticles and Metal-Organic Decomposition Inks with Different Curing MethodsMicromachines - Tập 11 Số 7 - Trang 677

Currently, inkjet printing conductive films have attracted more and more
attention in the field of electronic device. Here, the inkjet-printed silver
thin films based on nanoparticles (NP) ink and metal-organic decomposition (MOD)
ink were cured by the UV curing method and heat curing method. We not only
compared the electrical resistivity and adhesion strength of two types of silver
films, but al... hiện toàn bộ
Significant Involvement of Double Diffusion Theories on Viscoelastic Fluid Comprising Variable Thermophysical PropertiesMicromachines - Tập 12 Số 8 - Trang 951

This report examines the heat and mass transfer in three-dimensional second
grade non-Newtonian fluid in the presence of a variable magnetic field. Heat
transfer is presented with the involvement of thermal relaxation time and
variable thermal conductivity. The generalized theory for mass flux with
variable mass diffusion coefficient is considered in the transport of species.

A Review for Compact Model of Thin-Film Transistors (TFTs)Micromachines - Tập 9 Số 11 - Trang 599
Nianduan Lu, Wenfeng Jiang, Quantan Wu, Di Geng, Ling Li, Ming Liu
Thin-film transistors (TFTs) have grown into a huge industry due to their broad
applications in display, radio-frequency identification tags (RFID), logical
calculation, etc. In order to bridge the gap between the fabrication process and
the circuit design, compact model plays an indispensable role in the development
and application of TFTs. The purpose of this review is to provide a theoretical

Fabrication and Modeling of Matching System for Air-Coupled TransducerMicromachines - Tập 13 Số 5 - Trang 781
Jinjie Zhou, Jia‐qi Bai, Yao Liu
The tremendous acoustic impedance difference between the piezoelectric composite
and air prevents the ultrasonic transition, resulting in low amplitude for the
received signal for the composite defect detection using an air-coupled
transducer. The matching system, which includes the matching layers and bonding
layers attached to the piezoelectric composite, can reduce the acoustic
impedance differ... hiện toàn bộ
Analysis and Optimization of a Microchannel Heat Sink with V-Ribs Using Nanofluids for Micro Solar CellsMicromachines - Tập 10 Số 9 - Trang 620

It is crucial to control the temperature of solar cells for enhancing efficiency
with the increasing power intensity of multiple photovoltaic systems. In order
to improve the heat transfer efficiency, a microchannel heat sink (MCHS) with
V-ribs using a water-based nanofluid as a coolant for micro solar cells was
