Smart mattress

A personalized, sleeping posture correction system for a bedding article, the system comprising:

• a three-dimensional body for a user of the bedding article to sleep thereon being segmented into a plurality of compartments defining a plurality of pressure sensing and response zones;
• a pressure sensing and response module being disposed in each of the pressure sensing and response zones comprising one or more pressure sensing mechanisms and one or more actuators, each of the pressure sensing mechanisms and each of the actuators having individual sensor and actuator circuits in each of the pressure sensing and response zones configured to generate pressure sensing signal and execute actuation instructions, respectively;
• and
• a central processor receiving pressure sensing signals from the one or more pressure sensing mechanisms, processing thereof, sending actuation instructions to the one or more actuators, feeding the processed pressure sensing signals to and receiving corresponding commands from one or more external devices,
• wherein the one or more pressure sensing mechanisms are one or more multi-layered structures comprising at least one pressure sensing layer and two electrode layers, and the at least one pressure sensing layer is a textile made of piezoresistive yarns,
• wherein the one or more actuators comprises a two-layer actuator structure including a top layer and a bottom layer, the bottom layer being a layer of flexible materials and disposed beneath and underlying the entire top layer, the top layer comprising a plurality of airbags configured to be adjustable for adjusting overall height of the one or more actuators.
