Tumor cells are malignant derivatives of normal cells. There are characteristic differences in the mechanophysical properties of normal and tumor cells, and these differences stem from the changes that occur in the cell cytoskeleton during cancer progression. There is a need for viable whole blood processing techniques for rapid and reliable tumor cell detection that do not require tagging. Mic...

This paper deals with steady-state analysis of the magnetic field by using Finite Element Method (FEM) in salient poles synchronous motor with damper (SPSMD). The knowledge of electromechanical characteristics is very important in performance analysis of electrical machines, in general. In this paper it presents a methodology for numerical calculation of electromechanical quantities, starting w...

The homogenized energy framework quantifying ferroelectric and ferromagnetic hysteresis is increasingly used for comprehensive material characterization and model-based control design. For operating regimes in which thermal relaxation mechanisms and stress-dependencies are negligible, existing algorithms are sufficiently efficient to permit device optimization and the potential for real-time co...

Development of soft electromechanical materials is critical for several tantalizing applications such as soft robots and stretchable electronics, among others. Soft nonpiezoelectric materials can be coaxed to behave like piezoelectrics by merely embedding charges and dipoles in their interior and assuring some elastic heterogeneity. Such so-called electret materials have been experimentally sho...

Quantum electromechanical systems offer a unique opportunity to probe quantum noise properties in macroscopic devices, properties that ultimately stem from Heisenberg’s uncertainty relations. A simple example of this behavior is expected to occur in a microwave parametric transducer, where mechanical motion generates motional sidebands corresponding to the up-and-down frequency conversion of mi...

BACKGROUND Electromechanical and robotic-assisted gait training devices are used in rehabilitation and might help to improve walking after stroke. This is an update of a Cochrane Review first published in 2007. OBJECTIVES To investigate the effects of automated electromechanical and robotic-assisted gait training devices for improving walking after stroke. SEARCH METHODS We searched the Coc...

Nanoscale electronics seeks to decrease the critical dimension of devices in order to improve performance while reducing power consumption. Single-walled carbon nanotubes fit well with this strategy because, in addition to their molecular size, they demonstrate a number of unique electronic, mechanical and electromechanical properties. In particular, theory predicts that strain can have a large...

INTRODUCTION The role of robotics in poststroke patients' rehabilitation has been investigated intensively. This paper presents the state-of-the-art and the possible future role of robotics in poststroke rehabilitation, for both upper and lower limbs. MATERIALS AND METHODS We performed a comprehensive search of PubMed, Cochrane, and PeDRO databases using as keywords "robot AND stroke AND reha...

The advent of monolithic integration of mechanical structures with electronics has ushered an era in which microchips can sense and act as well as compute and communicate. The complex device, component and system design issues involving such integrated chips requires the development of new CAD representations, methodologies and tools. A suite of tools that simultaneously considers the mechanica...
