To be able to calculate the performances of a hybrid stepping motor or to design it in a short time, it is essential to apply an efficient model, accepting a slight loss of precision. Using software based on finite elements and executing calculations are d ...
This article shows the design of an assistive product and a proposal of a business plan for persons with motor disability in lower-limbs, in accordance with the guidelines for social inclusion of the World Health Organization (2001). The design project wit ...
In this paper, an improved design of a silicon micromachined gyroscope (angular rate sensor) is presented. It is based on the tuning fork principle and realized by combining two proof masses. The gyroscope is driven by electromagnetic forces and detects th ...
Just about every other technical publication you pick up these days makes sweeping statements concerning the pressures on scientists, engineers, and industries as a whole to get to market in less time, with an improved, less expensive product. I am reminde ...
This paper presents the design, fabrication and characterization of polymer microoptoelectromechanical systems (MOEMS). An optical accelerometer and a variable optical attenuator (VOA) based on SU-8 are presented. Both devices consist on a quad-beam polyme ...
This paper presents a novel development method for interactive and distributed applications. The benefit that this method provides is that the design gives clear guidance towards the implementation. The method is based on three main elements: a concept of ...
A new method for the detection of gait cycle phases using only two miniature accelerometers together with a light, portable digital recorder is proposed. Each subject is asked to walk on a walkway at his/her own preferred speed. Gait analysis was performed ...
Over the last few years there has been a growing interest in the domain of pedestrian navigation, stimulated by the increasing demand for Location Based Services. Pedestrian Dead Reckoning (PDR) based on MEMS sensors has been at the heart of most high-end ...
This paper discusses the analysis of reflectarray cells comprising MEMS control elements. The method employed allows a very fast and accurate analysis of the reflectarray cell performance, quasi independently of the number of embedded MEMS and reconfigurab ...
The use of nanowire crossbars to build devices with large storage capabilities is a very promising architectural paradigm for forthcoming nanoscale memory devices. However, this new type of memory devices raises questions regarding how to test their correc ...
