“…Air quality refers to the measurement of the state of the air in relation to human needs and is related to health. Pollution is used to describe substances that lower the air quality [15]. Nanosensors are used to monitor and identify air pollution in high concentrations for the purpose of monitoring toxins, heavy metals, and organic pollutants in air, water, and soil [13,16,9].…”

Today's age is characterized by large amount of information that surrounds us in which visual information plays a significant role. Nanosensor air quality measurement systems that use Internet of Nano-Things technology enable the collection of big data. Ease of display and storage of information that the user can easily interpret are imperative in designing a visual interface. Only a good combination of visual elements complemented by data and map display will contribute to the clarity of the processed data. This paper will give an overview of the factors that affect the excellence of the transmission of visual information. Ways of presenting visualizations of air quality data measured by IoNT systems will be discussed through descriptive and empirical analysis of visualizations. A special emphasis is on the review of existing practices and principles, and the possibilities of visual presentation of information in this area will be explained through the discussion.

“…To ensure portability, the integration between the gas sensors with a smartphone and portable devices allows people to be informed about the quality and safety of the air. Hence, the use of wearable sensors associated with wireless modules demonstrated the feasibility of point-of-care analyses, providing directions through the results obtained by the system detection in short times and high sensitivity for the target compounds. − In this way, Seok and collaborators described a system to detect volatile organic compounds using a gas-sensing system based on a capacitive micromachined ultrasonic transducer array integrated to a low-power wireless module. The device was applied for ethanol detection, obtaining an LOD of 120 ppb, consuming 80 μW of average power, and the power cycling when it was activated taking measurements at 3 s per min.…”

This current Review focuses on recent contributions of wearable and biodegradable sensors dedicated to health and environmental applications. Recent examples reported in the literature are presented and critically discussed in order to diagnose diseases and their response to treatment with a focus on cancer and Parkinson’s disease. Advances in devices for body temperature, humidity (skin hydration), human physiological signals, and metal detection in body fluids are demonstrated concerning simple and portable platforms. Studies performed outside the controlled laboratory environment can rapidly help in point-of-care analyses or self-examination by the patients. Environmental approaches are also outlined, aiming at gas detection, metal sensing, and environment humidity, including different substrates showing not only flexible and biodegradable sensors but also wireless detection and data communication. The discussed examples for health and environmental analyses have successfully demonstrated the considerable potential of wearable devices for real-time and on-site applications, highlighting the self-monitoring capacity. Future investigations should consider the device’s operational simplicity with a more straightforward interpretation of results to make them affordable for the market. The huge potential of wearable and biodegradable devices enables them as emerging and powerful platforms for replacing current gold standard methods for rapid health screening and environmental monitoring in the near future. The next trend in the technological field of the development and application of new biodegradable materials to wearable devices should focus on studies involving the stability, toxicity, and biocompatibility of the final devices.
