The resonance of microcantilever was piezoresistively detected by the wheatstone bridge on the root of the beam, for it responded to the thermally-excited from bi-material effect caused by different thermal expansion coefficient of Al and Si. 2.1 The output signal amplitude.
Taking into account the change of resistance, a reasonable simplification is as follows: (3) The bendingof a cantilever can be estimated from[4]: (4) Whereis the total cantilever thickness, is the cantilever length, and are the thermal expansion coefficients, is the thickness ratio of the two cantilever materials, and is the ratio of Young's modulus .

Fractional order model of Iron core Due to lightning overvoltage, operating overvoltage amplitude could be as high as 3 to 4 times of the rated voltage, electromagnetic PT iron core could have a lot of excitation flux, so the silicon steel sheet as a core material could achieve excitation saturation easily, and its changes of magnetic induction intensity always lags the change of its magnetic field strength, then produce hysteresis phenomenon that shows the shape of a hysteresis loop back through magnetic flux density B and magnetic field intensity H and shows multivalued nonlinear corresponding relationship[6].
Fractional order calculus can be effectively applied to simulate the dynamic characteristics of different types of materials[7].

Introduction Aluminum Oxynitride (AlON) is a transparent polycrystalline ceramic material of high strength and hardness.
Unfortunately, AlON is a refractory material; it requires high substrate temperatures (1300 K), which is complicated to obtain [6].
The sputtering target was 99.999% aluminum (Al) material.

It is clearly observed that the LED chip is wrapped mainly by five different materials.
Other materials, such as gold wires and cathode lead, also exist in the LED package but they are omitted in the model due to their negligible effect on the heat conduction problem in the module.
Thermal conductivity values, which are substantial for obtaining accurate and reliable temperature field information, are listed in Table 1 for the materials in a LED module.
