“…Impedimetric biofilm monitoring techniques have been adapted to flexible substrates for detection in complex environments [ 121 , 132 ]. In particular, our group has developed an IDE-based impedance sensor on a flexible polyimide substrate for integration with the cylindrical inner lumen of a catheter, where biofilms routinely form ( Fig.…”

“…Extensive data were collected in real time, in an experimental campaign carried out for a few months in the field (a pilot network of three nodes) in North Italy [2]. The same sensor, originally fabricated on rigid substrates [19], has later also been fabricated on flexible Kapton substrates, enabling its installation in pipes of small diameter (a few centimeters), typical of domestic networks and appliances [20].…”

Sensors and electronics technologies are pivotal in several fields of science and engineering, especially in automation, industry and environment monitoring. Over the years, there have been continuous changes and advancements in design and miniaturization of sensors with the growth of their application areas. Challenges have arisen in the deployment, fabrication and calibration of modern sensors. Therefore, although the usage of sensors has greatly helped improving the quality of life, especially through their employment in many IoT (Internet of Things) applications, some threats and safety issues still remain unaddressed. In this paper, a brief review focusing on pervasive sensors used for health and indoor environment monitoring is given. Examples of technology advancements in air, water and radioactivity are discussed. This bird’s eye view suggests that solid-state pervasive sensors have become essential parts of all emerging applications related to monitoring of health and safety. Miniaturization, in combination with gamification approaches and machine learning techniques for processing large amounts of captured data, can successfully address and solve many issues of massive deployment. The development paradigm of Smart Cities should include both indoor and outdoor scenarios.

“…Flexible electrodes, fabricated on Kapton substrates with the same geometries, have been also successfully realized ( Figure 3c). If bending takes place along the longitudinal orientation of the metal fingers, the measured sensitivity is the same as of the rigid version [41]. Since they can be conformally applied inside ducts with bending radii below 1 cm, they represent a viable solution for pipes of small diameters, such as in industrial and domestic appliances.…”

A smart, safe, and efficient management of water is fundamental for both developed and developing countries. Several wireless sensor networks have been proposed for real-time monitoring of drinking water quantity and quality, both in the environment and in pipelines. However, surface fouling significantly affects the long-term reliability of pipes and sensors installed in-line. To address this relevant issue, we presented a multi-parameter sensing node embedding a miniaturized slime monitor able to estimate the micrometric thickness and type of slime. The measurement of thin deposits in pipes is descriptive of water biological and chemical stability and enables early warning functions, predictive maintenance, and more efficient management processes. After the description of the sensing node, the related electronics, and the data processing strategies, we presented the results of a two-month validation in the field of a three-node pilot network. Furthermore, self-powering by means of direct energy harvesting from the water flowing through the sensing node was also demonstrated. The robustness and low cost of this solution enable its upscaling to larger monitoring networks, paving the way to water monitoring with unprecedented spatio-temporal resolution.
