The author discusses the sacrificial-layer method of making silicon micromotors, the use of electrostatic actuation, and the importance of friction and contact sticking in such devices. The persistent problem of finding meaningful applications for these tiny machines is discussed, touching a range of topics along the way. The future of computation using a register made of atoms, and quantum-mechanical transitions for computation operations, is looked at. > 
Micro-assembly and modeling of the liquid microworld : the PRONOMIA project
This paper presents an overview of the French research program PRONOMIA which deals with new methods for robotic micromanipulation and especially on submerged micromanipulation. During microscale
Micromanipulation using magnetic field
This work proposes a method of micromanipulation using magnetic force based upon linkage-free end-effectors and different from the concept of serial-link manipulators, which can be achieved as a link mechanism.
Analysis of forces for micromanipulations in dry and liquid media
During microscale object manipulation, contact (pull-off) forces and non-contact (capillary, van der Waals and electrostatic) forces determine the behaviour of the micro-objects rather than the

A historical perspective of the origin and development of MEMS is presented, as well as the traditional and innovative fabrication techniques, and several of the most important applications of microsystems in the manufacturing and production sectors are described.
Toward Colloidal Motors
We have presented the first direct observation of electric field induced rotation of epoxy based polymer rotors. Polymer disks and gears were prepared in few micrometer dimensions as rotors.
