Described herein is a method and techniques for subsurface monitoring. The system includes a downhole including a casting with a lumen, a wireless power transmitter within the casting, a micro-sensor cement mixture including a plurality of micro-sensors mixed with a cement, the micro-sensor cement mixture on a surface of the casting opposite from the lumen, a relay system including a plurality of relays, each of the plurality of relays including a charging component and a surface receiver. The wireless power transmitter configured to transmit a wireless power signal. At least one micro-sensor of the plurality of micro-sensors is configured to receive the wireless power signal, sense at least one attribute, and transmit a sensed signal. A series of relays are configured to receive the sensed signal and re-transmit the sensed signal and a surface receiver is configured to receive the sensed signal at a third time after the second time.
A system for subsurface monitoring, the system comprising:
A method comprising:
A first sensor ring for use in subsurface monitoring of an oil well, the first sensor ring comprising:
