Systems, methods, and apparatus for using aircraft bondline embedded current sensors to determine a lightning damage index are disclosed. A method of predicting lightning strike damage to at least one type of aircraft involves sensing, with at least one current sensor node embedded in at least one type of aircraft, induced current. The method further involves generating, with at least one current sensor node, at least one current signal representative of the induced current. Also, the method involves determining, electromagnetic density data associated with at least one region of at least one type of aircraft by using at least one current signal. Further, the method involves creating an index that provides a numeric representation for predicted lightning strike damage to at least one type of aircraft based on the electromagnetic density data, dimensions of at least one type of aircraft, and design features of at least one type of aircraft.
