MEMS combines microscale mechanical and electrical components to create integrated systems. In medical applications, MEMS enables new endoscopy devices like a "lab on a pill" with a camera and sensors to view the entire small intestine without sedation. MEMS also allows for smart pills that can automatically deliver drugs on demand when implanted in the body. MEMS technology is expanding what is possible in both sensing environments and controlling systems by merging small sensors and actuators with information processing.

2. What are MEMS?
 Micro(small)
 Electro(electric components/functionality)
 Mechanical(mechanical components/functionality)
 Systems(integrated, system-like functionality)

3. MEMS and endoscopy
. What is endoscopy ?
 A diagnostic procedure which involves the
introduction of a flexible device into the lower or
upper gastrointestinal tract for diagnostic or
therapeutic purposes.
Conventional endoscopes
 Can be used to view only the first
third of the small intestine.
 Require sedation of patient.
 It is an uncomfortable procedure

4. MEMS redefines endoscopy
with “Lab on a Pill”
Size : 35mm
Components of lab on a pill
 Digital camera (CMOS
Technology)
 Light source
 Battery
 Radio transmitter
 Sensors (MEMS
Technology)

7. MEMS AND DRUG DELIVERY

8. Smart Pill
 A MEMS device that can be implanted in the human
body.
 Automatic drug delivery(on demand).

10. CONCLUSION
MEMS technology is extending and
increasing the ability to both perceive and
control the environment by merging the
capabilities of sensors and actuators with
information systems.
MEMS are quietly changing the way you
live, in ways that you might never imagine
