摘要：Smart sensors comprising one or more microelectromechanical systems (MEMS)sensors and a digital signal processor (DSP) in a sensor package are described. Anexemplary smart sensor can comprise a MEMS acoustic sensor or microphone and a DSP

housed in a package or enclosure comprising a substrate and a lid and a packagesubstrate that defines a back cavity for the MEMS acoustic sensor or microphone.Provided implementations can also comprise a MEMS motion sensor housed in thepackage or enclosure. Embodiments of the subject disclosure can provide improvedpower management and battery life from a single charge by intelligently responding totrigger events or wake events while also providing an always on sensor that persistentlydetects the trigger events or wake events. In addition, various physical configurations ofsmart sensors and MEMS sensor or microphone packages are described.
