MEMS are integrated micro-scale systems combining electrical, optical or other（magnetic, mechanical, thermal, fluidic, etc.）elements typically fabricated using conventional semiconductor batch processing techniques, namely, MEMS are macro-engineering at microscale, they have two main features:（1）design structures/devices/systems at micro/nano scale, （2）typical microsystems involve multiple physical domains.
MEMS are a very complicated multidisciplinary field, in which physics, chemistry, materials science, mechanics and engineering play an important role.
Especially, it has translated physical properties and material characteristics into structures and devices that can have a large positive impact on people’s everyday life.
BioMEMS usually contains sensors, actuators, mechanical structures and electronics.

l MEMS involves electronics, machinery, materials, manufacturing, information and automatic control, physics, chemistry and biology and other disciplines.
Single chip integrated ofthe MEMS sensors, actuators micromechanical structures and signal processing circuitry to reduce system size, lower power consumption.Manufacturing real system on chip will be the future development trend.There are two ways to achieve single-chip integration: one is using complementary metal oxide semiconductor (CMOS) and integratedmanufacturing process of MEMS, thendirectly processing a MEMS micro-mechanical structure and processing circuitry on a single wafer; the other isprocessingASIC circuits and MEMS micro-mechanical structures respectively, achieving hybrid integration on the same substrate using thin film, thick film, or low temperature co-fired ceramic (LTCC) and other ways.

However, this improvement in thermal stability cannot be achieved if the fully exfoliated structure is not successfully produced [2].
In the area of slow crack growth, a stress-whitened and fibrillated structure can be seen.
The structure originated from ductile tearing of the ligament between holes during stable propagation; the fibrils were formed by the shearing of the matrix under tensile stress.

Each particle was used only in one experiment because after test, its state (its form, sizes, structure of near-surface layers) was changed.
Pyrolysis products are filtered in the microcellular structure of forest fuels to the surface of contact “a leaf-a particle”.

Because existing alcohols induced amylose to be single structure and put into spiral internal to degrade system energy.
Once the conditions were below standard, starch became only a single helical structure, without any guest molecules wrapped.
Potato starch was purchased from Zhu Cheng Xing Mao CO., LTD; analytical grade anhydrous ethanol, hexanol and DMSO from HAOHUA chemistry reagent Luo Yang CO., LTD;X-ray diffractometer, Burker D8 from Burker Co., Germany; Test method Preparation of B-type microcrystalline starch.The preparation method of B-type microcrystalline starch was referenced Reference[2].
Fig. 2 showed that, starch solution quickly added to hexanol ligand solution, amylose had not enough time to complex with hexanol ligand, single helical chains of amylose have to form the double helix structure of A-type crystal.

Starch has tows kinds structure, crystallizing field and amorphous region.
With the highly ordered internal structure, it’s hard to react with enzyme and other chemical reagent [1].

The structure of the gel formed in reduced gravity was compared to a normal-gravity control sample using standard NMR spectroscopic techniques.
In principle, Q4 groups oppose capillary stress and a sol-gel structure with a larger pore size, surface area and pore volume is usually formed.
The greater concentration of Q2 and Q3 groups and the dominance of surface tension affects in normal gravity would result in a microporous structure.

This might due to the poor workability and wood aggregates agglomeration, resulting in non-uniform wood particles dispersion, heterogeneous and less dense structures.
Fig. 5a shows the structure is denser and more compact with few pores.
On the other hand, in Fig. 5b – 5c, the geopolymer composite containing wood aggregates shows more pores and microcracks which weaken the structure.
