These Knowles mics are terrific for consumer applications. They very sensitive, smaller package, sound great, and have an integrated amplifier. From what I've seen of MEMs oscillators, I seriously doubt there will be an equivalently wonderful MEMS device that revolutionizes the oscillator market.
This is an excellent use of microelectromechanical engineering, even the I have also not heard any Professional Microphone manufacturer using MEMS Microphone, it would be surely giving better sound compared to the present day condenser microphones.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
