    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.
