The paper presented the development of high temperature piezoelectric wafer active sensor (HT-PWAS) and proposed the structural health monitoring (SHM) strategies for thermal protective system (TPS) SHM with HT-PWAS in harsh/high temperature environment. In addition, to facilitate the implementation of SHM principles and transmission of diagnosis results, a conceptual Self-powering Wireless Active Structural Health Monitoring Sensor (Sp-WASHMS) system is proposed. We envision that the HT-PWAS technology will open a variety of implementation options for USAF Space Operations Vehicles thermal protection systems. After being proven successful, this technology might be also applicable to the USAF aircraft jet engine and other reusable launch vehicles as well as NASA present Space-Shuttle and future Crew Exploration Vehicle (CEV). Our HT-PWAS possesses multiple diagnostic capabilities, and those are phased-array, pitch-catch, E/M impedance, and impact detection.
