Innovative Method for Wirelessly Powering RFID Tags Located on Rotorcraft

TDA"s research during this SBIR will incorporate the two main types of RFID technology: passive and active RFID systems. During previous research, TDA has shown that passive systems present challenges with respect to effective read range, as well as performance in a metal-rich environment. However, TDA believes that the performance of these systems can be enhanced via beam forming, impedance matching, and back scatter boosting techniques, as well as tag placement optimization. Similarly, TDA has shown that implementation of active tag systems is hindered by large tag form factors as well as undesirable battery maintenance requirements. TDA intends to research alternative means of powering these active tags, such as wireless power transmission. In addition, a major goal of this research will be to design and develop an ultra-low energy, solar powered active tag. By pursuing parallel lines of research in both active and passive technologies, TDA will be able to develop and recommend a complete and optimized system for the unique application of rotorcraft component tracking and sensing.
