Analyzing the electrical double layer (EDL) in electrical impedance spectroscopy (EIS) measurement at low frequencies remains a challenging task for sensing purposes. In this work, we propose two approaches to deal with the EDL in measuring impedance

In this pilot study, we characterize and evaluate 3D-printed swabs for the collection of nasopharyngeal and oropharyngeal secretion samples for the SARS-CoV-2 detection. Swabs are made with the fused deposition modeling technique using the biopolymer
Impedance measurement is a common technique to characterize and detect the electrical properties of biological cells. However, to decode the underlying physical processes, it requires complex electrical models alongside prior knowledge of the sample

According to the World Health Organization, 31% of worldwide deaths are due to cardiovascular diseases (CVDs). The principal cause of death in 85% of the CVD cases are heart attack and stroke. About 795,000 people have a new or recurrent stroke annua

Animal models for hepatic fibrosis are currently used for clinical studies, and research works aimed to the progression and regression of the disease. In these, fibrosis is evaluated using histopathological assessment with high variability inter- and

Electrical impedance spectroscopy (EIS) is a tool for characterizing the electrical behavior of matter. Nevertheless, most of the work is focused on purely experimental results, leading aside alternative measurement and estimation techniques. In this

We present the distribution of relaxation times (DRT) method applied to the electrical impedance spectrum data for improving the differentiation of biological tissues by means of two scenarios, a non-parametric representation and a parametric model.

We determined the thermal effusivity of liquids using an optical sensor based on the laser beam deflection technique, without directly heat the samples and thus minimally altering them. Applying a heat pulse in a thermo-optical slab we generate a uni
