Micro-Electro-Mechanical-Systems (MEMS)

Welcome friends, In the previous post I have explained introductory things on MEMS. Today I will discuss on the features of the same topic.

• Miniaturization : Micro machines (sensors & actuators) can handle micro-objects & move freely in small space about their mean position.
•  Multiplicity : (1)co-operative work from many small machines may be best way to perform a large task.  (2) Inexpensive to make many machine in parallel.
• Micro-Electronics : Integrate micro-electronics control devices with sensors & actuators

 MEMS - Basic micro-fabrication techniques

1. Bulk Micro-machining
2. Surface Micro-machining

MEMS- Structure

1. Cantilever Beams
2. Diaphragms
3. Electrostatic Motors

MEMS- Examples

1. Bulk micro-machined accelerometer
2. Single chip microphone
3. Single chip acclerometer ( Basically these are analog devices )
4. Lab-on-a-chip (Bio-MEMS)
5. Drug delivery system (Bio-MEMS)
6. DNA analyzer (Bio-MEMS)

MEMS - Impact on engineering

• A driver for multiple, mixed technology integration.
• Orders of magnitude increases in the number of sensors & actuators
• Beneficiary of & driver for information systems.
• VLSI as a design & synthesis approach for microelectronics.

MEMS- Multiple & mixed technology Integration

• Interdisciplinary terms will be needed.
• MEMS will counter the tendency for narrow specialization.
• Teams that best integrate multiple disciplines will be best positioned for future applications 
• New materials needed.

In short the space for research and development for MEMS is unlimited. In the next post I will introduce the topic on micro-sensors. Thank You very much.
