“…The most common ones are relative humidity (RH), absolute humidity, and dew point (DP) [ 1 ]. Various fields of application as well as the type of measurement unit (RH, DP) have required researchers to develop various types of humidity sensors [ 2 , 3 , 4 ]. In addition to the general requirements (linearity, reproducibility, accuracy, stability), the trend today is moving toward the development of sensors that can operate without relying on an external power supply, i.e., self-powered sensors [ 5 ].…”

A detailed examination of the principle of operation behind the functioning of the full-self-powered humidity sensor is presented. The sensor has been realized as a structure consisting of an interdigitated capacitor with aluminum thin-film digits. In this work, the details of its fabrication and activation are described in detail. The performed XRD, FTIR, SEM, AFM, and EIS analyses, as well as noise measurements, revealed that the dominant process of electricity generation is the electrochemical reaction between the sensor’s aluminum electrodes and the water from humid air in the presence of oxygen, which was the main goal of this work. The response of the sensor to human breath is also presented as a demonstration of its possible practical application.

“…Sensors have become so miniaturized that they can be integrated into virtually any wearable device or everyday object, such as smart watches and glasses, thus offering new forms of interaction [ 1 ]: a sensor is able to recognize human movements performed on some dedicated parts of the human body [ 2 , 3 , 4 ].…”

Presently, miniaturized sensors can be embedded in any small-size wearable to recognize movements on some parts of the human body. For example, an electrooculography-based sensor in smart glasses recognizes finger movements on the nose. To explore the interaction capabilities, this paper conducts a gesture elicitation study as a between-subjects experiment involving one group of 12 females and one group of 12 males, expressing their preferred nose-based gestures on 19 Internet-of-Things tasks. Based on classification criteria, the 912 elicited gestures are clustered into 53 unique gestures resulting in 23 categories, to form a taxonomy and a consensus set of 38 final gestures, providing researchers and practitioners with a larger base with six design guidelines. To test whether the measurement method impacts these results, the agreement scores and rates, computed for determining the most agreed gestures upon participants, are compared with the Condorcet and the de Borda count methods to observe that the results remain consistent, sometimes with a slightly different order. To test whether the results are sensitive to gender, inferential statistics suggest that no significant difference exists between males and females for agreement scores and rates.

“…Generally, antibodies specifically recognize the antigens and form a stable complex, which is then detected and analyzed (Taitt and optical, micromechanical, and piezoelectric (PZ) immunosensors (Aliofkhazraei and Ali 2014;Chauhan and others 2015). Contrary to other immunoassay methods, new developed transducers, such as quartz crystal microbalance (QCM) transducer do not necessarily need the use of labels for detecting the analyte.…”

The presence of mycotoxins in foodstuff causes serious health problems to consumers and economically affects the food industry. Among the mycotoxins, aflatoxins are very toxic and highly carcinogenic contaminants which affect the safety of many foods, and therefore endanger human health. Aflatoxin M 1 (AFM 1 ) found in milk results from the biotransformation of aflatoxin B 1 . Many efforts have been made to control the source of AFM 1 from farmers to dairy product companies. However, AFM 1 escapes ordinary methods of food treatment such as cooking, sterilization, and freezing, hence it appears in milk and dairy products. The presence of high levels of AFM 1 constitutes an alarming threat as milk and dairy products contain essential nutrients for human health, especially for infants and children. For this reason, there is a pressing need for developing a fast and reliable screening method for detecting trace aflatoxins in food. Several analytical methods based on high-performance liquid chromatography (HPLC) and mass spectroscopy have been used for aflatoxin detection; however, they are expensive, time-consuming, and require many skills. Recently, immunoassay methods, including enzyme-linked immunosorbent assay (ELISA), immunosensors, and lateral flow immunoassay (LFIA), have been preferred for food analysis because of their improved qualities such as high sensitivity, simplicity, and capability of onsite monitoring. This paper reviews the new developments and applications of immunoassays for the rapid detection of AFM 1 in milk.
