Material property monitoring and detection using wireless devices

A system for non-invasive monitoring of tissue, the system comprising:

• at least one lattice-of-sensors;
• wherein the at least one lattice-of-sensors comprises:
• a first-sensor-tag;
• wherein the first-sensor-tag comprises,
• at least one electric circuit comprising at least one sensor;
• at least one antenna in communication with the at least one electric circuit;
• a plurality of sensors, not of the at least one sensor of the first-sensor-tag, with an initial predetermined spacing between any two adjacent sensors selected from the plurality of sensors such that the plurality of sensors is arranged in a lattice framework;
• wherein the plurality of sensors are in electrical communication with the first-sensor-tag;
• wherein at least a portion of the plurality of sensors are physically connected to the first-sensor-tag;
• wherein a positional location according to a coordinate system of each sensor selected from the plurality of sensors is fixed and known by the system;
• wherein at least a portion of the at least one lattice-of-sensors is proximate to the tissue;
• wherein upon the at least one antenna receiving electromagnetic radiation of a predetermined characteristic as an input, this input causes the at least one circuit to take one or more readings from the at least one sensor of the first-sensor-tag or from at least one sensor selected from the plurality of sensors;
• and to then transmit the one or more readings using the at least one antenna;
• wherein the system further comprises at least one reader-and-calibration-member;
• wherein the at least one reader-and-calibration-member has its own antenna;
• wherein the at least one reader-and-calibration-member provides the electromagnetic radiation of the predetermined characteristic as the input;
• wherein the at least one reader-and-calibration-member is in radio communication with the at least one lattice-of-sensors;
• wherein the at least one reader-and-calibration-member receives the one or more readings;
• wherein the at least one reader-and-calibration-member comprises two or more reference-sensor-tags that have a location known by the at least one reader-and-calibration-member.
