Abstract


This study presents a new sensing paradigm of human and computer collaboration for structural health monitoring. The goal of this study is that, human pilots are able to “feel” wing’s structure responses (especially impacts in this study) and determine impact locations and strength by using a vibro-haptic interface. Both hardware and software components have been developed for this haptic system. L-shape piezoelectric sensor arrays are deployed to measure the acoustic emission data caused by impacts and unique haptic feedback signals are generated after processing the measured data. These haptic signals are wirelessly transmitted to an arm wearable haptic interface, which provides the information on impact locations and intensity. Our experimental results demonstrate that human could detect impact events and judge whether subsequent damage would occur or not by only using haptic interfaces. In addition, human could notice errors such as those caused by algorithm or DAQ failures by feeling haptic feedback signals. Several important aspects of this study, including development of haptic interfaces, human training strategies, and extension of the haptic capability into damage detection are summarized in this paper.
