Nowadays, the Micro Electro Mechanical System (MEMS) technology’ has been achieved great developments. Accelerometer is one kind of the most popular MEMS sensors due to it's widely applications. In order to fabricate any MEMS device, the design and simulation have been considered seriously. This paper presents a new design of the three degrees of freedom piezoresistive accelerometer to improve the sensitivity, urgent demand from the reality. The ANSYS software was utilized to design, simulate and evaluate the advantages of this new structure compared to other sensors fabricated previously.

This paper presents a feasibility step in the development of biomimetic microrobotic insects. Advanced engineering technologies available for applications such as the micro-electro-mechanical system (MEMS) technologies are used. A flapping-wing flying MEMS concept and design inspired from insects is first described. Then different kinds of materials used feasibly for flapping-wing microrobotic insect by MEMS technology, such as SU-8, Titanium alloy and Parylene-C, are discussed. And artificial insect wings and thoraxs with different materials by MEMS Technology are fabricated and analyzed. Finally, summarize the paper and propose future research priorities.

Forest tree poaching is a serious threat to forest resource and has an impact on the environment hence preservation of trees is a  must for mankind .This paper mainly aims at monitoring the trees using Micro –Electro mechanical system(MEMS) technology and employing vibration sensor , sound sensor, fire sensor. The vibration produced while cutting of trees using MEMS accelerometer is sent through Zigbee to the main server and the location is detected using GPS likewise if fire is detected the information is sent through IoT and it can be viewed by forest ranger hence alert message is sent to detect and avoid poaching of trees and fire in forest.

Micro-electro-mechanical system (MEMS) have recently seen their field of application extended to military. This is mainly due to the fact that MEMS technologies present a great to reduce the mass, cost, power consumption, while improving the reliability, performance and smartness. Application of MEMS technology, the micropyrotechnic igniter are produced.The principle is based on the integration of the potassium salt of 7-hydroxy-4,6-dinitro-5,7-dihydrobenzofuroxanide (KDNBF) material within a micropyrotechnic igniter, which is produced by MEMS with 3 by 3 micro-igniter. Each igniter contains three parts (the igniter chip, silicon chamber, KDNBF). One import point is the optimization of the igniter process obtaining Ni-Cr bridges with about 13Ω and Al bridges with about 350Ω, which are triggered by electrical power delivered to KDNBF. The resistance of Ni-Cr and Al bridges is used to sense the temperature on the KDNBF which are in contact. The other one point is firing testing of micropyrotechnic igniter. The ignition performance of micropyrotechnic igniter array are tested that including Ni-Cr bridges of the 50% sensitivity on voltage, current ignition is 10.83V,0.26A; including Al bridges of the 50% sensitivity on current ignition is 0.176A; the ignition of voltage is unstable. The experimental results will deeply contribute to the micropyrotechnic system. This paper will discuss all these point.

Application of MEMS technology, the micropyrotechnic igniter are produced.The principle is based on the integration of lead styphnate (LTNR) material within a micropyrotechnic igniter, which is produced by MEMS with 3 by 3 micro-igniter. Each igniter contains three parts (the igniter chip, silicon chamber, lead styphnate). One import point is the optimization of the igniter process obtaining Ni-Cr bridges with about 13Ω, which is triggered by electrical power delivered to LTNR. The resistance of Ni-Cr bridges is used to sense the temperature on the LTNR which is in contact. The other one point is the optimization of silicon chamber process obtaining incorporate configuration of micropyrotechnic igniter. The ignition performance of micropyrotechnic igniter array are tested with ignition voltage less than 13V. The experimental results will deeply contribute to the micropyrotechnic system. This paper will discuss all these point.

To monitor airborne nano-sized particles (NPs), a single-chip differential mobility particle sizer (DMPS) based on resonant micro cantilevers in defined micro-fluidic channels (µFCs) is introduced. A size bin of the positive-charged fraction of particles herein is separated from the air stream by aligning their trajectories onto the cantilever under the action of a perpendicular electrostatic field of variable strength. We use previously described µFCs and piezoresistive micro cantilevers (PMCs) of 16 ng mass fabricated using micro electro mechanical system (MEMS) technology, which offer a limit of detection of captured particle mass of 0.26 pg and a minimum detectable particulate mass concentration in air of 0.75 µg/m3. Mobility sizing in 4 bins of a nebulized carbon aerosol NPs is demonstrated based on finite element modelling (FEM) combined with a-priori knowledge of particle charge state. Good agreement of better than 14% of mass concentration is observed in a chamber test for the novel MEMS-DMPS vs. a simultaneously operated standard fast mobility particle sizer (FMPS) as reference instrument. Refreshing of polluted cantilevers is feasible without de-mounting the sensor chip from its package by multiply purging them alternately in acetone steam and clean air.
