Are you referring to RF Id tags? In my research lab we are doing some work with flexible circuits. Currently we are integrating screen printing technology with conductive inks. The main problem with flexible circuits involves powering the unit. With passive RF ID tags they required no to very little onboard power. The problem with these system, since they are passive it would require very expensive reader to transmit data the range of a couple hundred yards. I’m not a rigger but I believe this system could be cheaply sewn directly into all risers without affecting the quality of the risers.
