What are MEMS?

Micro(small)

Electro(electric components/functionality)

Mechanical(mechanical components/functionality)

Systems(integrated, system-like functionality)

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

MEMS redefines endoscopy with “Lab on a Pill” Size : 35mmComponents of lab on a

MEMS AND DRUG DELIVERY

Smart Pill A MEMS device that can be implanted in the

human body. Automatic drug delivery(on demand).

CONCLUSIONMEMS 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
