Abstract
Systems and methods for actuation of downhole devices are disclosed. The system includes a first cylindrical pipe having one or more first materials attached to an outer surface of the first cylindrical pipe, a second cylindrical pipe co-axial with the first cylindrical pipe and having a diameter greater than the first cylindrical pipe, the second cylindrical pipe comprising one or more second materials disposed on an inner surface of the second cylindrical pipe, wherein the first materials generate one or more signals when the first materials come in contact with the second materials, and a digital logic circuit configured to receive the one or more signals as input, and generate an output based on the input, the output configured for actuation of the downhole devices.
