Vesper’s latest piezoelectric MEMS microphone, the VM1010, is described as the first commercially available quiescent-sensing MEMS device. Drawing 3 µA while in listening mode, the device promises to dramatically advance voice and acoustic event monitoring. In sleep mode the mic preserves a high signal-to-noise ratio (SNR) to improve acoustic range. Notably, there is absolutely no SNR penalty from going into low power, extending the distance of far field voice control in battery-powered systems. Engineering samples of VM1010 are available now to qualified customers developing technologically advanced systems. Production samples will be available in Q4 2016.
