The TPMS Based on the Nano-Polysilicon Thin Film Pressure Sensor

Low Temperature Polysilicon Thin-Film Transistors on Flexible Substrates

We fabricated low-temperature polycrystalline silicon thin-film transistors (poly-Si TFTs) on flexible substrates using sputtered amorphous Si (a-Si) precursor films. The a-Si precursor films were deposited by using rf-magnetron sputtering system with argon-helium mixture gas to minimize the argon incorporation into the Si film. The a-Si films were laser annealed by using XeCl excimer laser and...

A Micro Oxygen Sensor Based on a Nano Sol-Gel TiO2 Thin Film

An oxygen gas microsensor based on nanostructured sol-gel TiO2 thin films with a buried Pd layer was developed on a silicon substrate. The nanostructured titania thin films for O2 sensors were prepared by the sol-gel process and became anatase after heat treatment. A sandwich TiO2 square board with an area of 350 μm × 350 μm was defined by both wet etching and dry etching processes and the wet ...

the role of task-based techniques on the acquisition of english language structures by the intermediate efl students

this study examines the effetivenss of task-based activities in helping students learn english language structures for a better communication. initially, a michigan test was administered to the two groups of 52 students majoring in english at the allameh ghotb -e- ravandi university to ensure their homogeneity. the students scores on the grammar part of this test were also regarded as their pre...

Piezoelectric Pressure Sensor Based on Enhanced Thin-Film PZT Diaphragm Containing Nanocrystalline Powders

MEMS Pressure Sensor With Two Thin Film Piezoelectric Read-Out

We propose the structure to have only two pares of PZT thin films on the basis of [11]. This causes the structure to become simpler and easier to fabricate. And except its first vibration mode that is also the base mode, the other modes have no effect on the acceleration measurement. So it can be a better choice for the measurement of acceleration and it can have a huge potential as a micro-sen...
