Microfluidic channels on the size of tens of microns are being developed for use in a variety of applications such as microreactors, DNA analysis, and micro total analysis systems. Among the fabrication techniques for microfluidic channels, the recently-developed rolled-up method provides a great opportunity to integrate tubular channels by selective underetching and release of a strained thin film from a substrate. In this work, microfluidic channels with large diameter-to-length aspect ratios have been fabricated by a rolling method. The micro-FTIR characterization demonstrated that the functional poly(VDF-TrFE) ferroelectric polymer was engineered in the micro channel. The ferroelectric properties of the microchannels were studied by piezoresponse force microscopy (PFM). Local hysteresis measurement suggests that the microchannels show good ferroelectric properties. Fluid moving and emptying of the microfluidic channels were captured by video microscopy. © 2012 Elsevier B.V. All rights reserved.

Generic object recognition is one of the most important fields in the artificial intelligence. Some cortex-like networks for generic object recognition are proposed these years. But most of them concentrated on the discussion about the recognition performance (such as recognition rate, number of objects to be recognized), not the practicability, i.e., implementation with ubiquitous devices and application in real time. This paper reports a try on implementation of a biologically-inspired where-what network (WWN), which integrates object recognition and attention in a single network, via parallelizing the various stages of the network training with CUDA on GPU to shorten the training time. The experiment on HAIBAO Robot exhibited in 2010 Shanghai Expo shows that this optimization can achieve a speedup of almost 16 times compared to the C-based program on an Intel Core 2 DUO 3.00 GHZ CPU in real environments. © 2012 Springer-Verlag GmbH.

The series of Where-What Networks (WWNs) is a brain-inspired developmental model that simulates the dorsal (where) stream and the ventral (what) stream that converge to the motor area in the frontal cortex. Since developmental learning is always incremental, the order of different stimuli should affect the outcome of learning. In contrast to the uniform distribution of stimuli across image frames used in prior WWN experiments, this work studies non-uniform distribution in the sense that during training one object is presented at all the image locations before another object is presented. A new mechanism called cell regenesis is introduced to enable a less-often used cell to recommit its neuronal resource to new stimuli. The experimental results shown in this paper indicate that WWN-6 can deal with object-wise incremental learning. © 2012 Springer-Verlag.

In this paper the solar energy absorption characteristic of Si nanopillar(SiNP)array solar cell with metallic nanodiscs(NDs)is studied via simulation by finite-difference time-domain *** seems that among the common metals including Au,Ag,Cu and Al,Cu is the best one for the enhancement of overall absorption. But it is further demonstrated that the additional absorption mostly comes from metal NDs which is useless for improving the performance of solar cells. Then we study the absorption of Si pillars and Si substrate separately,which indicates that metal NDs can enhance the absorption of Si pillars while decrease the absorption of Si substrate and the overall absorption is actually *** mechanism of the absorption enhancement within the SiNPs is also discussed.

A novel method for fabrication of high-frequency (>100 MHz) ZnO ultrasonic array transducers on silicon substrates

引用

AIP Conference Proceedings 2012年第1期1433卷 679-682页

作者： W. J. Xu X. M. Ji J. M. Gao J. Carlier J. Y. Zhang B. Nongaillard Y. P. Huang B. Piwakowski Département Opto-Acousto-Electronique I.E.M.N.

High-frequency ultrasonic transducer arrays are essential for efficient imaging in clinical analysis and nondestructive evaluation (NDE). However, the fabrication of piezoelectric transducers is really a great challenge due to the small features in an array. A novel technique is presented to fabricate thick-film ZnO ultrasonic array transducers. Piezoelectric elements are formed by sputtering thick-film ZnO onto etched features of a silicon substrate so that the difficult etching process for ZnO films is avoided by etching silicon. This process is simple and efficient. A 13-μm-pitch ZnO sandwich array is achieved with a thickness of 8 μm for 300 MHz. Finite element method is employed to simulate the wave propagation in water based on this new transducer configuration. The acoustic field results indicate this configuration has an acceptable performance. A potential application is proposed based on integration with microfluidics.
