Over the last two decades, a variety of micro-robotic systems have been developed including electrothermal, electrostatic, electrochemical, piezoelectric, and electromagnetic actuators based on MEMS technology. The development of these micro-actuators promises a revolution in biological and medical research and applications analogous to that brought about by the miniaturization of electrical devices in information technology. For example, controllable manipulation of these tiny actuators may enable precise temporal and spatial delivery of chemicals, micro-optics or microelectronics to specific targeted sites.

Microelectromechanical system (MEMS) is a new multi-disciplinary research field in recent years, which is an actuator or system composed of micro sensors, micro actuators, micro devices, signal processing system and control system. This paper mainly introduces the development of MEMS, technology characteristics, main processing materials and processing technology. At last it introduces the development and application of MEMS in the fuze system and aerospace system in detail for the future.

Study Results

Background : The use of information technology is often applied in healthcare. With regard to scientific research, the SINPE(c) - Integrated Electronic Protocols was created as a tool to support researchers, offering clinical data standardization. By the time, SINPE(c) lacked statistical tests obtained by automatic analysis. Aim : Add to SINPE(c) features for automatic realization of the main statistical methods used in medicine . Methods : The study was divided into four topics: check the interest of users towards the implementation of the tests; search the frequency of their use in health care; carry out the implementation; and validate the results with researchers and their protocols. It was applied in a group of users of this software in their thesis in the strict sensu master and doctorate degrees in one postgraduate program in surgery. To assess the reliability of the statistics was compared the data obtained both automatically by SINPE(c) as manually held by a professional in statistics with experience with this type of study. Results : There was concern for the use of automatic statistical tests, with good acceptance. The chi-square, Mann-Whitney, Fisher and t-Student were considered as tests frequently used by participants in medical studies. These methods have been implemented and thereafter approved as expected. Conclusion : The incorporation of the automatic SINPE(c) Statistical Analysis was shown to be reliable and equal to the manually done, validating its use as a research tool for medical research.

Abstract The efficiency of shape memory alloys for the MEMS technology has been recently demonstrated. Quasibinary intermetallic TiNi-TiCu alloys produced by rapid quenching from liquid phase in the form of thin (about 40 um) ribbons are an attractive material for the fabrication of micro-actuators due to their narrow temperature hysteresis of the shape memory effect (SME) and relatively large recoverable strain. In order to broaden the functionality of SME microdevices, in this work we have alloyed TiNiCu containing 25 at.% copper with aluminum. The results have shown that alloying with 0.6 at.% Al increases the cast characteristics of the composition and favors its amorphization. Upon crystallization by isothermal annealing or electropulse treatment the resultant microstructure and SME properties of the Al containing alloy change but slightly in comparison with the original alloy however there is a significant shift (by more than 15°C) of the SME temperature range toward lower temperatures.

Self-assembled monolayer coatings have shown great promise for dramatically reducing the tribological forces of adhesion and friction in microelectro-mechanical systems (MEMS). However, monolayer coatings often display significant degradation when exposed to extreme environments, dynamic sliding contact, and dynamic impact loading. This degradation is coupled with a corresponding increase in the tribological properties. In this study, the degradation of tridecafluorotri(dimethylamino)silane is examined under the typical operating conditions of MEMS technology using a specialized microdevice designed for characterizing the tribological behavior surface micromachines. Results of friction and adhesion degradation under normal loading and sliding contact are interpreted in relation to the primary degradation mechanisms of self-assembled monolayers.
