“…As the device is compressed horizontally the molecules come closer, hence a hopping mechanism takes place and the charges move from one molecule to another. This provides a free path for charges to move, enhancing the electric current and resulting in a decrease in impedance; this can also be mathematically represented as Equation 1, in which the thickness (T) of the active layer is directly related to the resistance (R) 27 :…”

“…A CI Disperse Orange 25, graphene and CNT composite-based multifunctional sensor was fabricated using rubbing-in technology within a range of 0-110 μm, and a 1.3-12.7-fold decrease in resistance was observed. 27 In recent years, several researchers have shown interest in fabricating strain gauges for measuring displacement. [28][29][30][31][32] Flexible impedance and capacitance tensile load sensors, 15 thermoelectric devices, 33 and pressure and displacement sensors 34 based on CNTs, have been presented in the literature.…”

This paper presents the proposal and characterisation of a flexible, shockproof, vibration-free, longitudinal and transversal compressive displacement sensor based on a composite of CI Disperse Orange 25 and carbon nanotubes created with an energy-free, drop-casting technique. The structural morphology of each layer is studied briefly through X-ray diffraction. Electric investigations of the sensors in the form of impedance were performed as a function of longitudinal and transversal compressive displacement at three different frequencies. The compressive displacements were measured from 0 to 250 µm at three fixed frequencies (ie, 1, 10 and 200 kHz). The impedance has an inverse relationship with longitudinal compressive displacement but a direct relationship with transversal compressive displacement. The frequency to impedance relationship is inverse with the sensitivity of the impedance as a function of longitudinal displacement. Because of their small size, light weight and simple fabrication technique and design, as well as their low cost and maintenance, these types of devices can be utilised across a wide range of medical applications, such as in rehabilitation centres, for machine status assessment during physiotherapy, and in robotic body parts, as well as for educational purposes in universities.

Among the different nanostructures involved in the improvement of material properties, carbon nanotubes occupy a specific place because of their small refractive index, extended surface, and large Young’s module, which can all provoke dramatic change in basic matrix material characteristics. Inorganic crystals, semiconductors, metals, conductive compounds, and some polymer structures whose surfaces are treated with carbon nanotubes demonstrate better features than the ones obtained before carbon nanotubes deposition. Thus, the areas of application for these unique nanostructure materials can be effectively extended, e.g., for optoelectronic use, in biomedicine, and display applications. In the current paper, the advantages of the laser-oriented deposition technique are shown in order to demonstrate how the main material parameters change drastically through the incorporation of carbon nanotubes.
