Millifluidic Synthesis of Core–Shell Resonators For Tunable Sonic BandGaps in Acoustic Metamaterials
Advanced Materials Interfaces, EarlyView.Millimeter‐scale core–shell acoustic resonators are fabricated by a gravity‐assisted dripping approach and incorporated into epoxy composites at controlled volume fractions. The resulting alumina–core resonator composites show tunable low‐frequency acoustic attenuation, demonstrating a scalable route for integrating locally resonant metamaterial units ...

A Sensor Array Optimization Method for Electronic Noses With Sub-Arrays
Sensors and Actuators B: Chemical, 2009Sensor array configuration needs to be optimized in developing an application-specific instrument of electronic noses. Currently, sensor array optimization is commonly done by feature selection techniques. These methods could solve how to optimize a sensor array. However, they could not figure out what are the unique functions that each sensor plays in

Integrated Sensor Array Optimization With Statistical Evaluation
Sensors and Actuators B: Chemical, 2010In a sensor array system, sensor selection is to select optimum sensor elements which as a whole can maximize the separability of sensor array responses to different analytes. The purpose is to improve the quality of input to a classifier, thereby, improve correct classification rate. This paper introduces an integrated approach of cluster analysis (CA)

Optimal positioning of sensors for a microphone array
Proceedings of ICASSP '94. IEEE International Conference on Acoustics, Speech and Signal Processing, 2002Sensor positioning has an important influence on the performance of array processing. The main contributions of the paper are the proposal of criteria to evaluate and to optimize the performance of an array of sensors through its geometric configuration, the number and the positions of the sensors.

Optimal design of linear array of sensors
[Proceedings] ICASSP 91: 1991 International Conference on Acoustics, Speech, and Signal Processing, 1991The authors address the issue of design of linear arrays of sensors with application to high-resolution direction-of-arrival (DOA) algorithms, and present the D-optimality based design criterion (DOBC). The design technique employs certain prior information in the cases of low-angle tracking and where targets are close to each other, and provides an ...

Optimization of the Geometry and Porosity of Microelectrode Arrays for Sensor Design
Analytical Chemistry, 2002This paper describes the systematic investigation of a range of microelectrode arrays with varying dimensions fabricated by standard photolithographic and reactive-ion etching techniques. As expected from theory, the electrochemical behavior of microelectrode arrays with a constant individual diameter varied strongly with center-to-center spacing, the ...

Optimal Sensor Array Configuration in Remote Image Formation
IEEE Transactions on Image Processing, 2008Determination of optimal sensor configuration is an important issue in many remote imaging modalities, such as tomographic and interferometric imaging. In this paper, a statistical optimality criterion is defined and a search is performed over the space of candidate sensor locations to determine the configuration that optimizes the criterion over all ...
