Zinc phthalocyanine compound-based photo-electric organic shock-proof disposable flexible sensors

Abstract

This research study introduces a multifunctional photo-electric sensor that utilises a semiconductor composite material and is implemented on a cellulose substrate. The flex electronic devices were manufactured using a rubbing-in technique that does not require energy. The investigation focused on using a compound consisting of zinc phthalocyanine and multi-walled carbon nanotubes (MWCNTs) as an active layer. However, aluminium top electrodes were utilized for photo-electric characterization, respectively. The surface type symmetry was designed to achieve disposable organic, shock-proof, and vibration-free electronic devices. They are then analyzed and characterized for their morphological and electrical parameters. The material structural analysis was performed with x-ray diffraction of materials, UV–Vis, photo luminance, Fourier-transform infrared spectroscopy, and for electrical characterization, the capacitance and impedance at varying ultra-violet (0–1300 W/cm), infrared (0–1580 W/m2), and frequency (0.1–200 kHz) were performed. Each parameter's influence is broken out in detail to illuminate the underlying physics of the results further. The results show that when Infrared intensity rises, impedance falls, whereas UV intensity increases. In the context of capacitance, it is observed that exposure to ultraviolet radiation leads to a decrease or increase in capacitance, while intensification of infrared light also results in a corresponding change in capacitance.Moreover, it can be observed that the sensitivity of electronic equipment exhibits a reduction when the frequency is increased. These devices have a wide range of applications, such as their use in food supply chains to safeguard food from the detrimental impact of high ultraviolet and infrared radiation on public health. They can also be employed in the medical industry for optical physiotherapy treatments and in universities for research purposes in countries that fall below the international poverty line, owing to their cost-effective fabrication technique.
