摘要

We present a complete, fully functional energy-autonomous audio sensor node with 6x5x4mm(3) form factor. The system uses a new audio processing IC integrated with a MEMS microphone, general purpose 32-bit processor, 8Mb Flash, RF transceiver with custom 3D antenna, PV cells for energy harvesting 4-32X processing IC performs audio acquisition with 4-32x compression. The complete stand-alone system achieves 38mins of speech recording and energy-autonomous operation in room light.
