“…NiPc-based organic photo field-effect transistors were demonstrated to be sensitive to humidity [90]. NiPc humidity sensors fabricated by drop-casting showed different sensitivity in room temperature capacitance and impedance variation when fabricated at different gravity conditions [91]. NiPc-based OTFTs are also sensitive to NO2.…”

In this work, the topic of the detrimental contact effects in organic thin-film transistors (OTFTs) is revisited. In this case, contact effects are considered as a tool to enhance the characterization procedures of OTFTs, achieving more accurate values for the fundamental parameters of the transistor threshold voltage, carrier mobility and on-off current ratio. The contact region is also seen as a fundamental part of the device which is sensitive to physical, chemical and fabrication variables. A compact model for OTFTs, which includes the effects of the contacts, and a recent proposal of an associated evolutionary parameter extraction procedure are reviewed. Both the model and the procedure are used to assess the effect of the annealing temperature on a nickel-1,4,8,11,15,18,22,25-octakis(hexyl)phthalocyanine (NiPc6)-based OTFT. A review of the importance of phthalocyanines in organic electronics is also provided. The characterization of the contact region in NiPc6 OTFTs complements the results extracted from other physical–chemical techniques such as differential scanning calorimetry or atomic force microscopy, in which the transition from crystal to columnar mesophase imposes a limit for the optimum performance of the annealed OTFTs.

“…Another nickel phthalocyanine-based humidity sensor was fabricated under different gravity conditions over a range of 25%-95% relative humidity (RH), and the highest decrease in impedance and greatest increase in capacitance were obtained by increasing the humidity by 1.8-and 1.5-fold, respectively. 36 Recently, a rubbing-in technology-based nickel phthalocyanine and CNT composite active layer over rubber substrate with predeposited indium tin oxide electrodes was characterised by us as a pressure sensor. The resulting electric characterisation demonstrated that, with an increase in pressure, the non-linearity coefficient of current density and voltage decreased from 3 to 2.…”

An organic multifunctional sensor based on a composite of nickel phthalocyanine colourant, multi-walled carbon nanotubes and rubber is investigated in this work. The whole surface-type device was fabricated over rubber substrate with rubbing-in technology, including multi-walled carbon nanotubes-based electrodes. The proposed shockproof and flexible sensor is investigated in terms of its electric parameters, that is, its resistance and impedance, while varying the humidity (42%-90% relative humidity), frequency (0.1-200 kHz) and temperature (30-68°C). The effect of each parameter is explained in depth to enhance the physics behind each outcome. The results demonstrate that impedance and resistance decrease with increases in temperature and humidity, while the sensitivity of the device decreases with an increase in frequency. These types of devices can be utilised by the medical industry for monitoring the humidity and temperature of patients while undergoing physiotherapy treatment.How to cite this article: Asghar U, Karimov KS, Ibrahim MA, Fatima N.
