Most assembly processes on the nano-scale take place in a Scanning Electron Microscope (SEM) for the reason of high magnification range of the microscope itself. Like all microscopes, the SEM delivers visual data just in two dimensions. This is a bottleneck for all assembly processes which require of course information of the parts to join in a third dimension. This paper shows an approach with...

New type of humidity sensor based on Carbon thin film active nano layers, modified with sodium salt of sulfonated Nickel phthalocyanine is presented. The sensor shows high sensitivity due to the high surface area of Carbon nanoparticles, good long-time stability and sensitivity in the range from 20 to 85 % relative humidity (RH). The response is linear in semilogarithmic plot – logarithm of imp...

Abstract This paper adopts the concept of random weighting estimation to multi-sensor data fusion. It presents a new random weighting estimation methodology for optimal fusion of multi-dimensional position data. A multi-sensor observation model is constructed for multi-dimensional position. Based on this observation model, a random weighting estimation algorithm is developed to estimate positio...

Optical nano-cavities are ideal platforms for label-free sensing. In this work, we demonstrated sensing of glucose concentrations at 10mg/dL with photonic crystal nanobeam sensor. The sensor exhibits high sensitivity and linearity covering the whole range of clinically relevant levels. Current device was fabricated in silicon-on-insulator platform and operated at telecom wavelength, and thus fu...

Because of the quickly growing demand to handle micro-and nanostructures, micro-and nanorobotics has become an active eld of research in the last years. One major problem of this new technology is how to build a sensor system that can control the robot motion within the required accuracy. For the micro and nano domain we speciied an accuracy of one micron and ten nanometers respectively. We emp...

Submitted for the MAR12 Meeting of The American Physical Society Designing super-selectivity in multivalent nano-particle binding1 FRANCISCO MARTINEZ-VERACOECHEA, DAAN FRENKEL, University of Cambridge — A key challenge in nano-science is to design ligand-coated nanoparticles that can bind selectively to surfaces that display the cognate receptors above a threshold (surface) concentration. Nano-...

This paper studied the problem of the throughput of multi-hop multi-relay wireless sensor networks based on the cooperative diversity technology. At first, the paper established the cooperative diversity model for multi-source, multi-sink and multi-relay sensor networks, on which the specific expression of throughput of wireless sensor networks was deduced, it not only prove that the throughput...
