“…Among the various sensors for detecting different physical quantities, the strain sensor has been extensively developed and widely used for mechanical engineering [21][22][23][24][25][26][27]. Accordingly, the DIW is also adapted to achieve novel strain sensors with improved performance including higher gauge factor (GF ≥ 10) and larger stretchability (ε max ≥ 20%) [24,28,29] than those of traditional metal foil strain gauge (i.e. GF ≤ 2 and ε max ≤ 2%, in general).…”

The full-field multiaxial strain measurement is highly desired for application of structural monitoring but still challenging, especially when the manufacturing for large-area sensing devices is quite difficult. In this work we propose an integrated strategy from layered circuit scheme to rapid manufacturing of strain rosette sensor array based on the direct-ink-writing (DIW) technology. Benefit from the innovative design with simplified circuit layout and the advantages of DIW for printing multilayer structures, here we achieve optimization design principle for strain rosette sensor array with scalable circuit layout, which enable a hierarchical printing strategy for multiaxial strain monitoring in large scale or multiple domains. The strategy is highly expected to adapt for the emerging requirement in various applications such as integrated soft electronics, nondestructive testing and small-batch medical devices.
