“…The dielectric properties of most materials depend on many factors, including frequency of the applied alternating electric field, chemical composition and structure of the material, and especially permanent dipole moments associated with water and any other molecules making up the material of interest (Wang et al, 2017). Multiple studies to explain the polarizability and the orientational effects of acrylonitrile-butadiene rubber (NBR) was done by observing changes in these electrical properties ( For example, studies on changes of electrical properties were introduced and some sort of instruments were recommended to be used in the food industry (Mohamad et al, 2015;Sairin et al, 2019). Parallel plate electrodes are one of the generally used probes to sense the moisture content in peanut oil (Butts, 2008).…”

This paper investigates the impedance spectroscopy technique in determining moisture content in Nitrile gloves. Interdigitated electrode was designed and fabricated, then evaluated on LCR Impedance meter subjected to frequency range of 100Hz, 120Hz, 1kHz, 10kHz, 20kHz and 100kHz. Samples of Nitrile gloves were compounded and prepared for different moisture content level and regression analysis was performed to evaluate the relationships between capacitance and moisture content of the glove samples. Experimental results indicated that the capacitance value is a strong function of moisture content in gloves and also that the capacitance of moisture content in Nitrile gloves decreased with increasing drying time over the measured frequency range whilst statistical analysis results have confirmed that the 1kHz, 10kHz and 20kHz signal frequencies have highest reliable prediction of the nitrile gloves’ moisture content with high R2 value of 0.96, 0.97 and 0.97, respectively. The ability to determine average moisture content of Nitrile gloves via a non-destructive and online method, utilizing a low-cost instrument, will be of considerable use in the glove industry. This method could also be extended to other types of gloves and rubber products.

“…However, their prices (>1k USD) and lack of adaptability still represent a barrier. Researchers have opted to develop low-cost narrow-spectrum spectrometers specifically for their application needs, many of them [27][28][29][30][31][32] using the integrated circuit (IC) AD5933 (Analog Devices), which integrates basic impedance spectroscopy functions. 33 To our knowledge, the novel "ABE-Stat" 34 was the first approach to fill the gap of a wide-spectrum low-cost impedance spectrometer.…”

“…The output frequency is defined by the FCW, stored at a 24-bit FCR, and an internal OSC of 16.776 MHz. The DDS comprises a 27-bit PAR, which allows for dividing f OSC by 2 27 ~ 134M. The first bits of PA define the address at which the LUTs are accessed by the DAC.…”
