The micromotor is an extremely small device a few millimetres or less in size. Micromotors in the order of microns are realised by MEMS technology. Important applications in biomedicine include ultrasound probes for blood vessels,1 microrobots for colon intervention,2 smart pills and nanolitre pumps. Other uses include actuators for MOEMS and small variable capacitors. One exciting implication ...

Research and development in microelectromechanical systems (MEMS) have made remarkable progress since the advent of the first electrostatic micromotor in 1987. Considerable efforts have been directed to the investigation of the failure mechanisms and reliability of electrostatic micromotors. This paper provides a brief overview of failure modes and mechanisms and solving methods in electrostati...

A highly efficient polymeric tubular micromotor doped with Pt nanoparticle@carbon nanotubes is fabricated by template-assisted electrochemical growth. The micromotors preserve good navigation in multi-media and surface modification, along with simple synthesis, easy functionalization and good biocompatibility, displaying great promise in biological applications.

The conception and fabrication of micromotors is comparatively new in the field of engineering and is gradually gaining more serious attention from scientists, engineers, researchers and manufactures. Their designs and prototypes are finding various applications in robotics, medical instruments and various other fields. This article tries to give a short description of the advance made in this ...

We introduce a compact two-photon fluorescence microendoscope based on a compound gradient refractive index endoscope probe, a DC micromotor for remote adjustment of the image plane, and a flexible photonic bandgap fiber for near distortion-free delivery of ultrashort excitation pulses. The imaging head has a mass of only 3.9 g and provides micrometer-scale resolution. We used portable two-phot...
