3. WHAT IS ACCELEROMETER?
• An accelerometer is an electromechanical
device that measures acceleration forces.
• The vast majority is based on
piezoelectric crystals, but they are too big
and to clumsy.

4. DIFFERENT TYPES OF ACCELEROMETERS
• Mechanical Accelerometer
• Capacitive Accelerometer
• Piezoelectric Accelerometer
• Micro – Chip Accelerometer

5. MECHANICAL ACCELEROMETER

6. CAPACITIVE ACCELEROMETER

7. PIEZOELECTRIC ACCELEROMETER

8. MICRO – CHIP ACCELEROMETER

9. APPLICATIONS OF ACCELEROMETER
• Engineering (Gesture Controlled Robots)
• Industry (Vibration Monitoring)
• Medical applications (can be helpful in making artificial organs)
• Navigation (GPS systems)
• Safety Air bags in Automobiles

10. VIBRATION MONITORING APPLICATION
• This method is used where there are devices who have
motors or any type of rotating element.
• It is known that any motor or any other rotating mechanism
will have vibrations during its working condition.
• MEMS sensor is used to keep track of these vibration so
that the machine health can be observed.

11. WORKING OF MEMS

12. • SAMPLE GRAPH OBTAINED DURING WORKINGS
