Many piezoelectric materials have been investigated to manufacture the piezoelectric energy harvester, such as PZT [3], AlN [4], PVDF [5], etc.
The capability of piezoelectric energy harvester that converts vibration energy to electric form depends on the direct piezoelectric effect of the piezoelectric materials.
The effect describes the piezoelectric materials’ ability to transform the mechanical strain to electrical charge.
To cut straight lines for fabrication of rectangle cantilever, dicing is an excellent method with a high aspect ratio and no requirement for the machined materials.

Introduction With transition metal complexes have formed due to optical, electrical and magnetic properties, electrochemical and photoelectrochemical catalytic delocalized π electrons are Dithiolate and diimine ligands are strong bidentate ligand, photosensitive and gas sensing applications, such as showing significant value and attracted much attention, especially species such complexes can be extended by allowing the central metal ion, the structure of the ligand was modified adjusted substituent effects, three-dimensional effects and solvent effects it has the diversity and nature of the structure adjustable degeneration, is the synthesis of metal precursors tetraaza Ye Lin and other macrocyclic polymers, self-assembling molecules important raw materials and molecular devices, thus becoming subject to physical, chemical and material science workers attached great importance to the work of the author is also quite interesting.
Dithiolate with α, α `- mixed diimine ligands neutral homogeneous transition metal complexes or complexes with metal ions on the body charge-transfer complex of electronic, electrochemical and other functions, and their use in chemical sensors , nonlinear optical materials, infrared dyes, electron conductors and magnetic materials may have potential applications in areas such as value, worthy of further study.

The elasto-plastic model of the steel material was implemented for the dynamic analyses.
In the numerical calculations the parameters of the non-linear elasto-plastic steel material were taken from the experiment.
Figs3a and 3b show both, the experimental and numerical, tensile test of the steel material.

Keywords: Thermoelectric materials, thin films, thermoelectric devices.
However, recent significant advances in the scientific understanding of quantum well and nanostructure effects on TE properties and modern thin layer and nano-scale manufacturing technologies have combined to create the opportunity of advanced TE materials with potential conversion efficiencies of over 15% [3].
The advent of these advanced TE materials offers new opportunities to recover waste heat more efficiently and economically with highly reliable and relatively passive systems that produce no noise and vibration [4, 5].
The power factor should be maximized and the thermal conductivity should be minimized in order to achieve high efficiency thermoelectric materials.

In order to follow the trend, automobile manufacturers have made their unremitting efforts in diverse aspects of materials research and development, designing and manufacturing.
For example, DP steel, TRIP steel and CP steel have become the first choice as materials for automobiles.
Completely transforming of marten site of the materials has caused the stress intensity to reach 1500 MPa.
High Strength Steel for Hot Stamping Processing Raw materials for high strength steel used in automobiles have tensile strength requirement of about 400-600 MPa.

The low surface energy, lack of active functional groups on the molecular chain, and surface hydrophobicity, which may result the fibers cannot easily dispersed in cement-based materials.
To produce a better fiber reinforced materials of higher interface bonding strength [7], the hydrophobic PP fiber should be chemically modified to hydrophilic PP fiber with rough surface.
