  2. What are MEMS? Micro electro-mechanical Systems • Micro – size lies in micro range. • Electro- includes Electronics. • Mechanical – include physical mechanical devices. • System.

  3. Introduction • Micro electro-mechanical systems (MEMS) are micrometer-scale devices that integrate electrical /electronic and mechanical elements. • They have been used in diverse applications, from display technologies to sensor systems to optical networks. • MEMS are attractive for many applications because of their small size and weight, which allow systems to be miniaturized.

  4. MEMS Accelerometer.

  5. APPLICATION OF MEMS • Inertial navigation units on a chip for munitions guidance and personal navigation. • Electromechanical signal processing for ultra-small and ultra low-power wireless communications. • Distributed unattended sensors for asset tracking, environmental monitoring, and security surveillance. • Integrated fluidic systems for miniature analytical instruments, propellant, and combustion control. • Weapons safing, arming, and fuzing.

  6. ADVANTAGES • Ease of production. • MEMS can be mass-produced and are inexpensive to make. • Ease of parts alteration. • Higher reliability than their macro scale counterparts.

  7. DISADVANTAGES • Due to their size, it is physically impossible for MEMS to transfer any significant power. • MEMS are made up of Poly-Si (a brittle material), so they cannot be loaded with large forces. To overcome the disadvantages, many MEMS researchers are working hard to improve MEMS material strength and ability to transfer mechanical power.

  8. CONCLUSION • Thus hereby we concluded our presentation ,MEMS is going to be the future of the modern technical field in the growth of micro sensor based applications such as automotive industries, wireless communication, security systems, bio medical instrumentation and in armed forces.
