'Wei-Hung Chiang' 'Kenneth J. Loh' 'Tzu-Kang Lin' 'Chia-Ming Chang' 'Dimitrios Chronopoulos'] Strain measurements are vital for monitoring the load-bearing capacity and safety of structures. A common approach is to affix strain gages onto structural surfaces. On the other hand, most aerospace, automotive, civil, and…

Strain mapping over a large area usually requires an array of sensors, necessitating extensive and complex wiring. Our solution is based on creating multiple sensing regions within the area of a single capacitive sensor body by considering the sensor as an analogical transmission line, reducing the connections to only…

'Carlo Menon'] Textile sensors transform our everyday clothing into a means to track movement and bio-signals in a completely unobtrusive way. One major hindrance to the adoption of "smart" clothing is the difficulty encountered with connections and space when scaling up the number of sensors. There is a lack of…

Strain is one of the most frequently monitored parameters in civil structural health monitoring (SHM) applications, and strain-based approaches were among the first to be explored and applied in SHM. There are multiple reasons why strain plays such an important role in SHM: strain is directly related to stress and…

In this paper, Rayleigh backscattering sensors (RBS) are used to realize shape sensing of beam-like structures. Compared to conventional shape sensing systems based on fibre Bragg grating (FBG) sensors, RBS are capable of continuous lateral sensing. Compared to other types of distributed fibre optic sensors (FOS), RBS…

'Zhenmin Luo' 'Gang Ge' 'Lin Zhang'] Flexible stress sensor arrays, comprising multiple flexible stress sensor units, enable accurate quantification and analysis of spatial stress distribution. Nevertheless, the current implementation of flexible stress sensor arrays faces the challenge of excessive signal wires…

— Soft robotics is applicable to a variety of domains due to the adaptability offered by the soft and compliant materials. To develop future intelligent soft robots, soft sensors that can capture deformation with nearly infinite degree-offreedom are necessary. Soft sensor networks can address this problem, however…

Flight control requires active sensory feedback, and insects have many sensors that help them estimate their current locomotor state, including campaniform sensilla, which are mechanoreceptors that sense strain resulting from deformation of the cuticle. Campaniform sensilla on the wing detect bending and torsional…

Crop genetic engineering for better root systems can offer practical solutions for food security and carbon sequestration; however, soil layers prevent direct visualization. Here, we demonstrate an original device with a distributed fiber-optic sensor for fully automated, real-time monitoring of underground root…

We demonstrate a hybrid distributed fiber sensing system for multi-parameter detection. The integration of phase-sensitive optical time domain reflectometry (Φ-OTDR) and Brillouin optical time domain reflectometry (B-OTDR) enables measurement of vibration, temperature and strain. Exploiting the fast changing property…

Touch deforms, or strains, the skin beyond the immediate point of contact. The spatiotemporal nature of the strain field induced by touch depends on the mechanical properties of the skin and the tissues below. Somatosensory neurons that sense touch often innervate large regions of skin and rely on a set of…

'Marius Enachescu' 'Dominik Ziegler'] Distributed chemical sensing is demonstrated using standard acrylate coated optical fibers. Swelling of the polymer coating induces strain in the fiber’s silica core provoking a local refractive index change which is detectable all along an optical fiber by advanced distributed…

This study presents the use of laser-driven microbubbles for micro-patterning Ti3C2TX MXenes on flexible polyethylene terephthalate films, yielding conductive micropatterns without the need for pre- or post-processing. Characterization of the electrical properties under varying strain conditions revealed distinct…

A broad class of animals rely on touch sensation for perception. Among insects, the American cockroach P. americana is a touch specialist that uses a pair of soft antennae with distributed sensors to touch its environment to guide decision making. During touch, forces on the antenna can activate thousands of…

'Pratap M. Rao'] Abstract— This letter describes the manufacturing and experimental characterization of novel stretchable strain sensors for continuum robots. The overarching goal of this research is to provide a new solution for the shape sensing of these devices. The sensors are fabricated via direct ink writing, an…

Cutaneous mechanosensory neurons are activated by mechanical loads applied to the skin likely to result in local mechanical strain within sensory neurons. Using a microfluidics device to deliver controlled stimuli to intact animals and large, immobile and fluorescent protein-tagged mitochondria as fiducial markers in…

Cross-linked gold nanoparticle (GNP) assemblies are valuable for a variety of applications, such as transducers for strain or gas sensors. To pave the way for understanding their sensing behavior on an atomistic scale, we ask whether their properties can be modeled by a single, flat, particle–particle interface.…
