1. A method for producing a smart yarn, the method comprising:
aligning a set of sensing elements offset along a lateral axis in a magazine, each sensing element in the set of sensing elements comprising:
a sensor;
a first conductive lead extending from a first side of the sensor along a longitudinal axis perpendicular to the lateral axis; and
a second conductive lead extending from a second side of the sensor opposite the first side and along the longitudinal axis;
wrapping a set of fibers into a yarn within a wrapping field;
feeding a leading end of a first sensing element, in the set of sensing elements, from the magazine into the wrapping field;
releasing the first sensing element from the magazine into the wrapping field;
encasing the first sensing element between the set of fibers within the yarn;
in response to a trailing end of the first sensing element passing through the wrapping field following release of the first sensing element from the magazine into the wrapping field, feeding a leading end of a second sensing element, in the set of sensing elements, from the magazine into the wrapping field;
releasing the second sensing element from the magazine into the wrapping field; and
encasing the second sensing element between the set of fibers and longitudinally offset behind the first sensing element within the yarn.
