Luc,

I assume you are asking if anyone has developed a handheld mems device.
Yes, all of them are. A better right question is whether power and data
interfaces have been integrated in a unified MEMS framework.  For sure not.
I believe systems-on-a-chip that include a MEMS device aboard are still
many years away. In fact even to provide power to most MEMS devices is
beyond the capabilities of a battery.  As an academic exercise you should
try to do a back of the envelope calculation of the amount of power
required to actuate for a decent period of time any mechanical parameter in
microdimensions. Power losses through Joule heating effect (resistance) are
simply insignificant when compared to mechanical losses associated to
friction and heating.  Remember that the power required to compensate for
gravity forces is insignificant in MEMS, friction and surface tension are
enormous. (relative to macroscale examples)
