Hello,
I am a student of electrical engineering and I need to do a report on
MEMS micro tweezers.
Some questions that need to be addressed are

*       What is the range of forces (to the nearest order of magnitude)
that can be applied with these tweezers?
*       Where might these be useful in the medical industry?
*       Limitations and possible hazards in using this type of tweezers
in a medical application.
Some factors to be considered are : precision, force, voltage
size,safety


Someone please help me out here and tell me where to search for info. My
search has been quite useless till now.

Thanks

Shruti
