In this paper we demonstrate a novel characterization technique for the observation of the conductive filament in conductive bridging memory devices (CBRAM). The conductive filament is observed for a scaled memory element programmed under 10μA operative current. After the electrical programing, the C-AFM tomography enables the 3D analysis of the conductive filament within the switching layer.
Tactile sensing is an important field of research in the domains of human-computer and human-robot interaction. To provide appropriate tactile sensing capabilities, this work presents the development of a new modular tactile sensor system focusing especially on high frame rates (up to 1.9 kHz) and good spatial resolution (5 mm). Larger sensor areas are composed from identical sensor modules providing...
This paper considers the determination of the mode shapes using x-ray topography and the application of this method to resonant piezoelectric devices made of various materials (Quartz, LGS, Lithium tantalate). The basis of the method is recalled briefly and its application to thickness mode resonators or filters is particularly considered. A comparison of the observed mode shapes with those computed...
Aiming at complex shape of cylinder with multiple diagonal slits and difficult to processing using traditional processing method. the paper adopt two methods of EMD shaping and trajectory to processing slits of cylinder with multiple diagonal slits. Compared the processing quality of two processing method by the following aspects, such as the electrode material and fabrication technology, the level...
A system is proposed for monitoring changes in surface shape that is portable, inexpensive, durable, and works in many places where traditional shape monitoring techniques would fail. This system is ideally suited to monitoring large-scale surface deformations on surfaces like cloth without excessive wiring or the need for special purpose equipment. It is composed of a semiconductor-insulator-semiconductor...
Material transfer in a low-power direct-current switchgear is commonly known to cause contact failures to open due to mechanical interlocking, which is determined by (i) the shape of the material transfer pip-and-crater formation and (ii) the relative movement of the contact pieces during contact separation. The aim of this work is to analyze the influence of multiple arcing parameters on the evolving...
Ordered microporous carbon molecular sieves with high specific area and well-dispersed Pt nanoparticles have been prepared by chemical vapour deposition method. Electrochemical properties were measured, showing the nitrogen-doped carbons exhibited excellent performance as an electrochemical supercapacitor.
Because of the complex geometry shapes and structures of mould cavities, identifying the regions that should be eroded by EDM has become a time-consuming and error-prone work for toolmakers. A fuzzy approach to automatically select optimized processing method for manufacturing features is proposed in this paper. Some examples are also included for discussion. The results showed that this approach...
In order to promote the flexibility about the selection of transmission corridor, DC gas-insulated transmission line (GIL) can be utilized to substitute part of the overhead line. One of the key factors that greatly threaten insulation level of GIL is the accumulation of surface charges along the supporting insulators under DC voltage. In this paper, the sphere-plane electrode system has been established...
Dielectric Elastomer is considered as a kind of promising biomimetic actuator material which behaves similar to human muscle and can produce significantly large strain at high pre-stretch. It generated considerable interests in recent years for use in robotics and mechatronic applications. This paper is mainly on fundamental planar actuation experiment from which we abstract some Voltage-Area deformation...
Trees in silicone rubber has been investigated using 2-D specimen. The tree is classified two, i.e. 1st and 2nd tree. The behaviors of these trees have been observed by changing the ratio of two components of silicone rubber. The 1st tree is usually linear but the bubble has been formed in the soften silicone rubber. When the 1st tree is round babble, it is difficult for the 2nd tree to start from...
Electrical capacitance tomography is targeted on estimating the spatial permittivity distribution of an inhomogeneous medium from measurements of trans-capacitance of a multi-electrode assembly outside the boundary of the medium. Since small changes in the measured data cause large or unbounded changes in recovered parameters, the problem is an ill-posed inverse problem. In this article, special focus...
Advances in micromachining technology can facilitate the integration of SAW (Surface Acoustic Wave) devices and CMOS circuitry on IC scale substrate for Monolithic fabrication. The optimal design and performance of these filters can be reached by using new Smart materials. The key component in the structure of the SAW device is the piezoelectric materials used which depends mainly on some important...

Three types of the cascaded thermoelectric modules operating up to 850 K in high electrode temperature and two types of Bi-Te thermoelectric modules operating...
In this paper active damping of a beam as an example of shape control of flexible structures is studied. The purpose is to stabilize significant modes of motion with piezoelectric actuator-sensor. Using a one dimensional partial differential equation model, a variational method is used to find a dissipative energy function. A criteria for the design of the shape of the piezoelectric material or electrode,...
