“…Regarding passive remote sensing, silks offer high fidelity signal transmission [ 9 ], and this paper has shown that the signal thread structure itself also contributes towards stable signal transmission properties. Furthermore, the structure also could be applied in active remote sensing applications, for example through implementation in piezoelectric energy harvesting materials and structures, where deformation (for example from vibration) is transformed into electricity [ 41 ]. Inspired by the signal thread design, these piezoelectric fibre bundles could come in a variety of sizes for different contexts, from microelectromechanical systems (MEMS), to large cables for civil applications [ 42 ], where deformation response can be closely controlled through bundle tensioning.…”

Remote sensing allows an animal to extend its morphology with appropriate conductive materials and sensors providing environmental feedback from spatially removed locations. For example, the sector web spider Zygiella x-notata uses a specialized thread as both a structural bridge and signal transmitter to monitor web vibrations from its retreat at the web perimeter. To unravel this model multifunctional system, we investigated Zygiella's signal thread structure with a range of techniques, including tensile testing, laser vibrometry, electron microscopy and behavioural analysis. We found that signal threads varied significantly in the number of filaments; a result of the spider adding a lifeline each time it runs along the bridge. Our mechanical property analysis suggests that while the structure varies, its normalized load does not. We propose that the signal thread represents a complex and fully integrated multifunctional structure where filaments can be added, thus increasing absolute load-bearing capacity while maintaining signal fidelity. We conclude that such structures may serve as inspiration for remote sensing design strategies.

“…[ 17 ] Later on, as a more integrated approach, ZnO nanorods were grown on woven carbon fabric and aramid fiber with Cu and carbon fibers as a top electrode, respectively, to fabricate CFRP‐based devices to harvest energy from impact and vibration. [ 18,19 ] Furthermore, in order to improve the devices’ flexibility and mechanical properties for wearable applications, polydimethylsiloxane (PDMS) has also been used as encapsulation for ZnO nanorods grown on CF substrates. [ 20 ] Organic piezoelectric materials, such as polyvinylidene fluoride or polyvinylidene difluoride (PVDF), have also been incorporated with ZnO nanorods on CF to obtain higher performance.…”

The integration of piezoelectric materials onto carbon fiber (CF) can add energy harvesting and self-power sensing capabilities enabling great potential for "Internet of Things" (IoT) applications in motion tracking, environmental sensing, and personal portable electronics. Herein, a CF-based smart composite is developed by integrating piezoelectric poly(3,4-ethylenedioxythiophene) (PEDOT)/CuSCN-coated ZnO nanorods onto the CF surfaces with no detrimental effect on the mechanical properties of the composite, forming composites using two different polymer matrices: highly flexible polydimethylsiloxane (PDMS) and more rigid epoxy. The PDMS-coated piezoelectric smart composite can serve as an energy harvester and a self-powered sensor for detecting variations in impact acceleration with increasing output voltage from 1.4 to 7.6 V under impact acceleration from 0.1 to 0.4 m s −2 . Using epoxy as the matrix for a CF-reinforced plastic (CFRP) device with sensing and detection functions produces a voltage varying from 0.27 to 3.53 V when impacted at acceleration from 0.1 to 0.4 m s −2 , with a lower output compared to the PDMS-coated device attributed to the greater stiffness of the matrix. Finally, spatially sensitive detection is demonstrated by positioning two piezoelectric structures at different locations, which can identify the location as well as the level of the impacting force from the fabricated device.

“…In the "additive" approach, flexible polymers are added into the piezoelectric ceramics to improve the mechanical flexibility, increase the lifetime and optimize the electromechanical properties of piezoelectric composites. With the "additive" approach, the multifunctional piezoelectric composites show great potential in energy harvesting, 1,2 vibration and shape control, [3][4][5] structural health monitoring, 6 and so on. In the "subtractive" approach, the porous piezoelectric material can be regarded as the two-phase composite composed by piezoelectrically active and passive (pores) phases.…”

In this study, the ultra‐low porous auxetic piezoelectric composite made of lead zirconate titanate (PZT) and hollow polyvinylidine difluoride (PVDF) is first proposed by combining “additive” and “subtractive” approaches. The electromechanical properties of the auxetic piezoelectric composite are investigated by finite element analysis. It is found that the ultra‐low porosity in the composite may lead to great extensibility along with the excellent figures of merit obtained in conventional highly porous piezoelectric ceramics. The small amount of additional PVDF can greatly tune the electromechanical properties of composite and effectively reduce the maximum stress of PZT. To elucidate the role of Poisson’s ratio on the electromechanical properties of piezoelectric materials, the relationship expressions among some electromechanical coefficients are derived. Moreover, the semi‐empirical expression of “longitudinal” compliance coefficients and a simple strategy for predicting some electromechanical coefficients are presented to instruct design and application of the ultra‐low porous auxetic piezoelectric materials.
