Intrinsic structural damage monitoring of advanced composite laminates with embeddable 3D sensors network

Abstract

Solid state 3D photosensors have been developed using thermally-stable and highly conductive a) titanium microwires (TM) and b) carbon nanotubes (CNT) microyarns (CNYs). The real-time photosensors consist of TM and CNY as working electrodes (WEs). The highly inter-aligned, ultrastrong and flexible CNYs show excellent electrical conductivity, mechanical integrity and catalytic property. The open circuit voltage and current density of the cells can remarkably be improved through optimizing the numbers of CNYs and engineering of CNYs-TiO 2 interface. Optimizing the number of CNYs in the electrodes yields a remarkable photoconversion efficiency with prolonged-time stability. The sensors are able to transport the electrical response over a significant distance using a simple configuration with a wide range of structural flexibility.
