摘要

A sensing sheet based on large-area electronics consists of a dense array of discrete short-gauge sensor units, integrated circuits for collecting, analyzing and communicating data, and a flexible photovoltaic system that serves as both a power harvester and a protective layer. We investigated the sensitivity of thin-film full-bridge strain sensors to cracks, and the effect of crack position with respect to the sensor. In general, the results of this research show that full-bridge strain sensors can successfully detect and characterize cracks in structural materials and are therefore good candidates to utilize in a sensing sheet.
