(57) A well monitoring system may provide a plurality of integrated chips dispersed in cement surrounding a well casing. Each of the integrated chips may provide energy harvesting circuitry, EM transceiver, modulator, additional sensor(s), processor or microprocessor, memory, power source, or the like. Upon analyzing data gather from the sensor(s), emitted and detected EM waves, the system may provide information about the cement thickness at different parts of the well, cement setting/curing, local electrical permittivity, local magnetic permeability, temperature, pressure, pH, local NMR spectrum, local ESR spectrum, local florescence response, local porosity, local permeability, etc. Further, the integrated chips may be utilized to transmit/receive the above mentioned data, other data (e.g. command data, power signal, etc.), or the like to/from the main transceiver.
