2. INTRODUCTION
• MEMS is a technology of very small devices. It is a
combination of mechanical functions and electrical
functions on the same chip
• MEMS are made up of components
between 1 to 100 micrometers in size.
• MEMS are attractive for many applications
because of their small size and weight

3. What are MEMS?
(Micro-electromechanical Systems)
 MEMS devices sense, think, act and
communicate.

4.  MEMS are constructed on one chip with
electrical circuitry for inputs and outputs of
the electromechanical components.
 The interaction of electronics, mechanics,
light or fluids working together makes up a
micro-electro-mechanical system or
MEMS.
 Include motion, light, sound, chemistry,
biochemistry, radio waves and
computation, but all on a single chip

6. Applications of MEMS

7. In Automotive
Heavy use of MEMS is found in automotive such
as in
• Air bag systems,
• Vehicle security system,
• Vehicle dynamic control,
• Rollover detection,
• Vehicle Navigation Systems,
• Automatic door locks
• The Sensor Cluster etc.

10. MEMS in the Medical Field
• A MEMS is a device that can be implanted in
the human body.
• MEMS surgical tools provide the flexibility and
accuracy to perform surgery.

11. MEMS AUGMENTATION
• Hearing Aids

12. • Sight

13. • Kidney

14. MEMS in the Diabetes patient
A) Chemical
sensor
B) To the patient.
C) Measures the blood
glucose and a
transmitter
D) That sends the
measurement to the a
computer in (A)

15. Digital Tattoo
Digital tattoo monitors blood below the
skin

16. • The Heart ( Cardio-MEMS )

17. MEMS MICRONEEDLES
 MEMS enables hundreds of
hollow micro-needles to be
fabricated on a single patch of
area.
 This needles is applied to
the skin and drug is
delivered to the body using
micro-pumps.
 Micro-needles small so can
easily reach and stimulate
the nerve endings.

19. Advantages
 Minimize energy and materials.
 Improved reproducibility.
 Improved accuracy and reliability.
 Increased sensitivity.

20. Disadvantages
 Farm establishment requires huge investments.
 Micro-components are costly compared to macro
components.
 Design includes very much complex procedures

21. CONCLUSION
Thus hereby we concluded our
presentation in the topic of MEMS which 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.
