“…The shell structure theory states that the resistivity of any conductive composite is affected by the application of external pressure, due to the formation and destruction of conductive networks. A similar mechanism has been published previously by utilizing copper in the case of carbon-like diamond composites [21] or in carbon nanotubes composites in a wide range of polymer composites materials [22]. In this study, the pressure sensitivity was heightened by using increasing amounts of fillers, which resulted in a large number of filler-filler and filler-polymer interactions.…”

The preparation methodology and properties of electroconductive, electrospun mats composed of copolyamide 6,10 and Ti3C2Tx are described in this paper. Mats of several compositions were prepared from a solution of n-propanol. The obtained electrospun mats were then tested as piezoresistive sensors. The relative resistance (AR) of the sensor increased with an increase in the Ti3C2Tx content, and materials with relatively higher electrical conductivity displayed noticeably higher sensitivity to applied pressure. The pressure-induced changes in resistivity increased with an increment in the applied force.

“…A full review of these applications would be out of the scope of this paper, so only a few examples will be given. The usage of HPPMS has been demonstrated for different applications such as hard coatings [2][3][4], optical thin films [5][6][7], electrical applications [8][9][10], catalysis [11][12][13], adhesive and/or low friction coatings [14,15], anti-bacterial thin films [16], and conformal coatings [17]. The technique has introduced also some interesting new insight in terms of plasma physics which are presented in a large number of scientific papers, and summarized in a few highly cited reviews [5,[18][19][20].…”

“…First, intrinsic piezoresistive materials with high gauge factor (the specific value of resistance variation against strain), such as silicon film and carbon film, were used. [18,19] Although the GF of these materials can reach more than 2000, sensors made of these materials can only apply to small-strain environments due to the fragility of the materials. [20] Another avenue is to introduce microstructures, such as pyramid, [21] in the piezoresistive sensors to enhance the change of electrical contact resistance (ECR).…”

Microporous conductive nanocomposites, compared with conventional filler-matrix composites, enable flexible piezoresistive sensors with higher sensitivity and a larger measurement range. Previous research focuses on different methods of fabricating porous materials that are highly sensitive to pressure, however, there is only a small amount of research studying the mechanism of those sensors. Without an appropriate theoretical guide, relying on expensive experimental approaches to enhance the sensitivity will significantly limit the advancement of this technology. This article proposes an efficient analytical model, with some parameters determined from experiments, to investigate the piezoresistive behaviors of microporous nanocomposites. The predicted results agree well with the analysis from finite element models as well as the experimental data. Moreover, scaling law is applied to study the effect of geometry, material, and interface on the sensitivity of the sensor. This study establishes the theoretical foundation for the design of a high-performance piezoresistive sensor based on microporous nanocomposites.
