3d sensing using solid-state wire-shaped photovoltaic sensor in tl-based structural health monitoring

Abstract

Over the past two decades, photovoltaic (PV) cell research continues to gain momentum since its environmental sustainability and low cost provide a great foundation for practical application. Recently, the flexibility of PV cell has drawn researcher’s attention when talking about light sensing. The specially designed PV sensors with 3D feature and low energy sensitivity are potentially applicable to intrinsic structural health monitoring (iSHM) systems. This Chapter will first address the principle of this novel monitoring systems with TL effects, then discuss the use of carbon-based PV sensors. The investigation of wire-shaped PV sensor may provide some useful information about the surface and interface state that may explain the advantage of this novel iSHM system.
