Micromechanisms fabrication: a challenge in micromechanics and microelectronics
1992 IEEE International Solid-State Circuits Conference Digest of Technical Papers, 2003Micromechanisms fall into two broad categories: sensors and actuators. Actuators convert electric energy to mechanical energy, whereas sensors convert physical quantities such as force and pressure to electronic signals. The sensor area, in particular the resonating sensor, appears to have the earmarks of practical applications.

Sensor Letters, 2007
We have designed and fabricated micromechanical magnetometers intended for a 3D electronic compass which could be embedded in portable devices. The sensors are based on the Lorentz force acting on a current-carrying coil, processed on a single crystal silicon resonator.

Adhesion in micromechanical systems
Automation and Remote Control, 2017In this paper adhesion is considered as a factor that to a large extent defines the reliability of technological processes in microelectromechanical systems (MEMS) manufacturing using superficial technology. The physical and chemical conditions of its emergence are investigated, as well as the short-range and superficial forces causing adhesive ...

Micromechanics of magnetorheological suspensions
Physical Review E, 2000We apply optical trapping techniques in a magnetorheological (MR) suspension, allowing us to directly measure the mechanical properties of single dipolar chains, such as the rupturing tensions and strains under tensile and lateral deformations. Our results are in excellent agreement with calculations of the rupturing tensions using a self-consistent ...

Micromechanics of the Reptilian Ear
International Journal of Audiology, 1983This paper reviews selected physiology and anatomy of the lizard peripheral auditory system and presents the implications of these data for understanding cochlear micromechanics. The reasons for studying the micromechanics of the lizard ear are presented along with the difficulties in conducting such studies in the mammal.

Abstract Micromechanics deals with micromechanisms which fall into two broad categories: sensors and actuators. Since sensors measure some property of their environment, internal sensor power dissipation should be minimized and sensor sensitivity must be maximized. In force sensing, power dissipation has been reduced by ten decades in

Micromechanics of chromatin and chromosomes
Biochemistry and Cell Biology, 2003The enzymes that transcribe, recombine, package, and duplicate the eukaryotic genome all are highly processive and capable of generating large forces. Understanding chromosome function therefore will require analysis of mechanics as well as biochemistry.

Design of Compliant Micromechanisms
2006A broad overview of the topics related to the mechanical design of compliant micromechanisms is presented. Design methodologies to be used in the design of devices based on leaf springs, flexural notches and continuum structures with distributed compliance are given, and a critical presentation of the peculiarities of these solutions is provided.

A model of cochlear micromechanics
Hearing Research, 1997A cochlear model is presented which has two degrees of freedom, the motion of the basilar membrane and that of the tectorial membrane (TM), in every cross section of the organ of Corti. It assumes that the reticular lamina is virtually rigid, so that the apical portion of the outer hair cells is firmly anchored to it, and also that the TM is directly ...
