Abstract

Guided wave ultrasound is a very powerful and reliable nondestructive testing technique. The emerging smart structure health monitoring strategies demand a wireless sensor for most applications. Passive sensor interfacing with wireless technology is advanced due mainly to the mW power requirements of such sensors. Guided wave sensors, on the other hand, are active sensors that require orders of magnitude more power than the typical passive sensor. Consequently, the design of the sensor, embedded electronics, and adjacent power source become more complicated. Sensor accessories can be minimized by locating zones on the phase dispersion curves where modes are efficiently generated. In this paper, this concept formulated via the source influence phenomenon. Experimentation focuses on quantifying the activation power requirements in different zone of the dispersion curves.
