Abstract
A kind of integration node with six-microphone array for wireless sensor network (WSN) using 3D-SiP technology was developed. The node includes sensing module, communication module, battery compartment and node case. Communication and sensing modules were stacked by using vertical interconnections (including stand-off and stamp-hole) method. The sensing module contains six MEMS microphones and corresponding sound signal processing chips, master chip of signal processing, etc. On-line test result showed that the fabricated node has good performances, i.e. target recognition and classification. Vibration and shock test results showed that the integrated node has good reliability and environmental adaptability.
