Speakers and microphones:
Inside this pillow, there are multiple miniature speakers present that can connect through wireless connectivity like Bluetooth to your smartphones or any smart gadget that provides wireless connectivity to stream your favorite music or audiobook. Several microphones of this gadget are acting as the primary unit to detect your snoring. If you are snoring during your sleep then microphones detect it and send the signal to the control board for further processing.
Sleep tracking sensors:
The sleep motions are being tracked by these sensors. These are the Accelerometer and Gyroscope.
The Accelerometer is a kind of sensor that is responsible to detect the position and orientation during sleep. In the modern technological advancement era, MEMS are being used in the manufacturing of Accelerometers.
MEMS understand by the term Micro-Electro-Mechanical Systems. It is a technology that in its most general form can be defined as miniaturized mechanical and electro-mechanical elements (i.e. devices or components) that are made using the techniques of micro-fabrication.
MEMS components are categorized based on their various applications like Micro-sensors. Micro-sensors are designed to detect physical or environmental changes, for example – Infrared sensors, Accelerometer, Gyroscopes, etc.
To know more about MEMS go to Springer-journals. Smart integration of the MEMS Accelerometer forms into inertial measurement units providing precise navigation and sensor bias for good long-term stability. So Accelerometer is an electromechanical device.
It is a kind of motion sensor. It is doing the same function as it is doing in your smart phones or watches.
