“…[20,28] 3D printing, also known as additive manufacturing, has been recently used to fabricate flexible devices for its advantages of high accuracy, simplicity, and rapid prototyping. [29] Common 3D printing technologies for manufacturing flexible devices include digital light processing (DLP), [30] direct ink writing (DIW), [31,32] and fused deposition modeling (FDM). [33,34] However, FDM molding is time-consuming and the resolution of FDM-based device is relatively low.…”

High-performance flexible strain sensors with cost-effective and scalable fabrication methods are highly demanded for human-machine interfaces, soft robotics, and health monitoring. Herein, a digital light processing-based 3D printing method, which manufactures structures in a scalable and efficient layerby-layer manner, is developed to prepare a type of flexible strain sensors consisting of reduced graphene oxide/elastomer resin (RGO/ER) composite as the strain sensing element and RGO/ER composite with rhombic structure as the electrode. The RGO/ER composite as the sensing element has a sensitivity of 6.723 at a linear strain detection range from 0.01% to 40% and a high mechanical stability of more than 10 000 stretching-relaxing cycles. Furthermore, through the structural modulation, the sensitivity of the composite responding to mechanical deformation is modulated and suppressed, which can be used as the electrode for the strain sensor. The all-3D printed device with structurally modulated performance can be used for monitoring various human motions.

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.

“…Finally, PI substrate was deposited onto the PZT 39 ; (e) fabrication process of multi-material DIW-printed resistance strain sensor. 105 sensor network as an encapsulation layer and the hightemperature resistant working substrate was etched off. In this way, the high-temperature process was not applied to the flexible substrate, and the sensor-substrate alignment process and welding integration were avoided.…”

Through the integration of advanced sensors, actuators, and micro-processors, aircraft smart skin technology can improve the structural performance of aircraft and make them self-perception, self-diagnosis, self-adaptation, self-learning, and self-repair. Aircraft smart skin for structural health monitoring (SHM) is an important type of aircraft smart skin and has received extensive attention in recent years. Large-scale, lightweight, and low-power consumption are three key problems hindering the realization and engineering applications of aircraft smart skin for SHM. In view of these problems and restrictions of practical aircraft onboard applications, this article reviews the current research progress on aircraft smart skin for SHM, introduces their design, materials, manufacturing process, and monitoring principles in detail, and discusses how they study above problems from these aspects. Finally, perspectives are proposed on the opportunities and future developments of aircraft smart skin for SHM.
