With the great progress of production process，MENS have applied to a lot of areas in recent years，and today they have become "fundamental devices"，which are comparable with the IC. In this paper，we first discuss the main distinct advantages of MEMS as well as the important differences between MEMS and IC，then some latest research progresses on biomedical MEMS applications and MEMS sensor technology for harsh environment applications are briefly reviewed. Finally，possible future developments of MEMS are prospected.

Abstract An ellipsometry based measurement protocol was developed to evaluate changes to MEMS sensor surfaces which may occur during packaging using unpatterned test samples. This package-level technique has been used to measure the 0-20 Angstrom thin films that can form or deposit on die during the packaging process for a variety of packaging processing conditions. Correlations with device performance shows this to be a useful tool for packaged MEMS device and process characterization.

Background: Suaeda is a halophytic genus belonging to the Amaranthaceae family and can survive in the high salted marsh areas of the world. Suaeda plants can biosynthesize natural substances with powerful antioxidant activity and are considered as a renewable source of energy, food, and edible oil for a larger number of populations living in the harsh environment with high salinity and drought conditions. These plants also meet folk and alternative medicines' needs. Methods: The review encompasses available scientific literature related to folk medicinal uses of Suaeda plants, their nutritional values, and chemical constituents. In addition, the biological trials applied for the Suaeda plants are also part of the review. The review covers the researches from major science literature search engines and other sites representing scientific literature, i.e., Scifinder, Google Scholar, PubMed, ScienceDirect, Scopus, and Google. The searches were programmed on the advance options available in the search engines and are latest up to November 2019. The searches were exhaustive and rechecked for accuracy. Conclusion: The study summarizes the uses of Suaeda plants as a remedy for various ailments due to their contents from the polyphenols and flavonoids. The comparatively large amounts of fixed oils, minerals, and vitamins in Suaeda plants have also made them potential renewable sources for foods.

ABSTRACT The presence of massive stars (MSs) in the region close to the Galactic Centre (GC) poses several questions about their origin. The harsh environment of the GC favours specific formation scenarios, each of which should imprint characteristic kinematic features on the MSs. We present a 2D kinematic analysis of MSs in a GC region surrounding Sgr A* based on high-precision proper motions obtained with the Hubble Space Telescope. Thanks to a careful data reduction, well-measured bright stars in our proper-motion catalogues have errors better than 0.5 mas yr−1. We discuss the absolute motion of the MSs in the field and their motion relative to Sgr A*, the Arches, and the Quintuplet. For the majority of the MSs, we rule out any distance further than 3–4 kpc from Sgr A* using only kinematic arguments. If their membership to the GC is confirmed, most of the isolated MSs are likely not associated with either the Arches or Quintuplet clusters or Sgr A*. Only a few MSs have proper motions, suggesting that they are likely members of the Arches cluster, in agreement with previous spectroscopic results. Line-of-sight radial velocities and distances are required to shed further light on the origin of most of these massive objects. We also present an analysis of other fast-moving objects in the GC region, finding no clear excess of high-velocity escaping stars. We make our astro-photometric catalogues publicly available.
