Interfacing and Processing Artificial Hairs Array for Flow Pattern Recognition
نویسندگان
چکیده
Inspired from crickets and using MEMS techniques, single artificial flow sensors and hair sensor arrays have been implemented successfully in different groups [1][2]. This paper discusses the latest developments in interfacing and signal processing of cricket inspired artificial hair-sensors arrays. Sensor arrays require large number of connections for their elements to be interrogated individually. The objective of this work is to investigate the use of multiple sensors arranged in array structures, compared with single sensors, for detection and extraction of information from flow-patterns while exploiting only a limited number of electrical connections. Once this is achieved, recognizing specific flow signatures would become possible. Different schemes for individual sensor interfacing are investigated. Frequency Division Multiplexing (FDM) is found to be the most efficient and convenient especially with a huge number of array elements.

Flow-sensor arrays uncover the potential to measure spatio-temporal flow patterns rather than flow measurements at just a single point. We present in this paper the developments in design, fabrication and interfacing of biomimetic flow-sensor arrays, inspired by flow-sensitive organs (cerci) of crickets. For the purpose of high-resolution flow field visualization by our artificial hair flow-sen...

We present monolithically integrated high-density arrays of artificial hairs for flow pattern measurements based on drag force. A combined bulk/surface micromachining process has been developed to integrate the artificial hairs with capacitive read-out. First fabrication results show the possibility to fabricate out-of-plane hairs without reverting to micro-assembly technologies. This enables r...

Many researchers adopt Local Binary Pattern for pattern analysis. However, the long histogram created by Local Binary Pattern is not suitable for large-scale facial database. This paper presents a simple facial pattern descriptor for facial expression recognition. Local pattern is computed based on local gradient flow from one side to another side through the center pixel in a 3x3 pixels region...

The most ordinary way of information exchange is Speech. It provides an efficient way of man-machine communication using speech interfacing. Speech interfacing involves two process, speech synthesis and speech recognition. Speech recognition allows a computer to identify the words that a person speaks to a microphone or telephone. The two main mechanism, used in speech recognition, are signal p...
