We present a micro electromechanical tunable capacitor with a low control voltage, a wide tuning range and adequate electrical quality factor. The device is fabricated in a single-crystalline silicon layer using deep reactive ion etching (DRIE) for obtaining high-aspect ratio (> 20) parallel combdrive structures with vertical sidewalls. The process sequence for fabrication of the devices uses o...

At present, quantitative data is often used for fault diagnosis of electromechanical devices, while qualitative in the form text rarely used. In order to integrate and an device, a text-oriented method based on belief rule base (BRB) proposed this paper. Specifically, key information extracted from through natural language processing (NLP) then converted into rules. Then, supplement adopted add...

The electricity supply quality largely depends on the synchronized operation of generators. To increase reliability synchronization generators, it is necessary to adjust a turbine rotation frequency in coordinated method. In this case, advisable use an electromechanical control system for changes permissible generator tur-bine speed range. This article considers issue mathematical description s...

INTRODUCTION We incorporated patient feedback from human factors studies (HFS) in the patient-centric design and validation of ava®, an electromechanical device (e-Device) for self-injecting the anti-tumor necrosis factor certolizumab pegol (CZP). METHODS Healthcare professionals, caregivers, healthy volunteers, and patients with rheumatoid arthritis, psoriatic arthritis, ankylosing spondylit...

A new class of vibration energy harvester based on magnetostrictive material (MsM), Metglas 2605SC, is designed, developed and tested. It contains two submodules: an MsM harvesting device and an energy harvesting circuit. Compared to piezoelectric materials, the Metglas 2605SC offers advantages including higher energy conversion efficiency, longer life cycles, lack of depolarization and higher ...
