Monitoring tag device systems and methods

A method of monitoring curing of a concrete material starting as a wet slurry material, said method comprising:

• placing a plurality of tag devices within said wet slurry material, each of said plurality of tag devices comprising a sensing component, a wireless unit and a control component;
• using said plurality of tag devices to measure and communicate sensed variations of a plurality of parameters of said wet slurry material over time, wherein said plurality of parameters are related to material properties of said wet slurry material;
• and
• detecting a cure state over time of said wet slurry material curing to said concrete material by analyzing said sensed variations of said plurality of parameters of said wet slurry material over time.

A system for monitoring and recording variations in one or more parameters of a subject material transitioning from an uncured state to a cured state, said system comprising:

• a tag device operable to be disposed within said subject material in said uncured state, said tag device comprising:
• a sensing component configured to sense variations in a parameter, of said one or more parameters, over time as said tag device is within said subject material, wherein said parameter is related to a material property of said subject material;
• a wireless unit configured to communicate information related to sensed variations of said parameter over time to a remote unit;
• and
• a control component coupled to the sensing component and configured to control the sensing component and the wireless unit;
• and
• said remote unit operable to receive and record said information related to said sensed variations of said parameter over time to generate a mapping and wherein said mapping is operable for use to determine said cured state of said subject material.
