1. A monitoring mat for a user comprising:
a first layer used for weight measurement, comprising a plurality of force measurement sensors;
a second layer, used for pressure measurement, comprising a plurality of pressure sensors in a plurality of pressure locations of a pressure matrix;
a third layer, used for bio-impedance measurement, comprising a plurality of conductive sensors configured for direct contact with skin of the user and distributed throughout a surface of the third layer in a plurality of conductive locations of a bio impedance matrix, wherein respective pressure sensors at the plurality of pressure locations are positionally correlated with at least one conductive sensor at the plurality of conductive locations; and
a plurality of conductive pathways for each of the layers for connecting the plurality of force measurement sensors, the plurality of pressure sensors and the plurality of conductive sensors to an electronic controller device for generating and receiving measurement data,
wherein a subset of the plurality of conductive sensors is activated based on pressure measurement data generated by the plurality of pressure sensors.
