Problems. Rapid technical progress has led to a reduction in the useful life of consumer electronics. The introduction of green, flexible, biodegradable electronic devices will prevent an environmental catastrophe. Recently, the use of organic materials instead of inorganic analogues has become increasingly popular, which makes it possible to move from rigid solid-state sensors for multiple use that require disposal to flexible, disposable sensors that are suitable for human wear on the body or clothing and for spontaneous decomposition in nature after using. One of such promising organic materials is nanocellulose. The aim of the study. Studying the possibility of nanocellulose application for the manufacture of flexible, wearable, disposable sensors of various types of physical and chemical quantities. Methodology of implementation. In the article the analysis, classification and comparision of various technologies and features of synthesis, as well as the main characteristics of flexible sensors made on the basis of nanocellulose were fulfilled. Also the main parameters of flexible sensors based on nanocellulose were being compared with corresponding analogs of sensors based on artificial polymers. Research results. The paper established the physical and technological features of using nanocellulose for the manufacture of sensors of various types of physical and chemical quantities in order to improve their performance. It has been established that nanocellulose can be used both as a substrate and as a sensitive element of a sensor. It has also been shown that nanocellulose is suitable for use in sensors based on both electrical physical phenomena and optical effects. Conclusions. Nanocellulose is a promising biodegradable material on the basis of which flexible, disposable, wearable sensors can be created. The manufacturing technology of such sensors should contain only low-temperature and dry processing processes. For effective use in certain types of sensors, it is advisable to manufacture nanocellulose with a modified surface or in the form of composites with other nanomaterials. Based on the obtained results, it is possible to improve existing and develop new methods of creating flexible wearable disposable sensors that do not require disposal.

“…This possibility opens the way to exploit NP strain sensors as vibration sensors, which are of interest in various application fields ranging from voice recognition [21] to condition-based monitoring (CbM) of machines, which can enable cost savings on machine life and maintenance [22]. A recent review on the use of strain sensors for vibration sensing suggested that resistive strain sensors have a potential that needs to be further investigated, due mainly to their low cost and low weight, especially when compared to accelerometers, which are currently the industry standard for vibration sensing and monitoring [23].…”

Flexible electronics have gained a lot of attention in recent years due to their compatibility with soft robotics, artificial arms, and many other applications. Meanwhile, the detection of acoustic frequencies is a very useful tool for applications ranging from voice recognition to machine condition monitoring. In this work, the dynamic response of Pt nanoparticles (Pt NPs)-based strain sensors on flexible substrates is investigated. the nanoparticles were grown in a vacuum by magnetron-sputtering inert-gas condensation. Nanoparticle sensors made on cracked alumina deposited by atomic layer deposition on the flexible substrate and reference nanoparticle sensors, without the alumina layer, were first characterized by their response to strain. The sensors were then characterized by their dynamic response to acoustic frequency vibrations between 20 Hz and 6250 Hz. The results show that alumina sensors outperformed the reference sensors in terms of voltage amplitude. Sensors on the alumina layer could accurately detect frequencies up to 6250 Hz, compared with the reference sensors, which were sensitive to frequencies up to 4250 Hz, while they could distinguish between two neighboring frequencies with a difference of no more than 2 Hz.

“…Alternative strain-type sensors can be used to evaluate the extent of the damage and its location. In fact, this type of sensor has shown remarkable accuracy and applicability in the literature [ 28 , 29 , 30 ]. However, a large number of this type of sensor might be needed to monitor the structure’s structural properties entirely [ 31 ].…”

Structural damage detection using inclinometers is getting wide attention from researchers. However, the high price of inclinometers limits this system to unique structures with a relatively high structural health monitoring (SHM) budget. This paper presents a novel low-cost inclinometer, the low-cost adaptable reliable angle-meter (LARA), which combines five gyroscopes and five accelerometers to measure inclination. LARA incorporates Internet of Things (IoT)-based microcontroller technology enabling wireless data streaming and free commercial software for data acquisition. This paper investigates the accuracy, resolution, Allan variance and standard deviation of LARA produced with a different number of combined circuits, including an accelerometer and a gyroscope. To validate the accuracy and resolution of the developed device, its results are compared with those obtained by numerical slope calculations and a commercial inclinometer (HI-INC) in laboratory conditions. The results of a load test experiment on a simple beam model show the high accuracy of LARA (0.003 degrees). The affordability and high accuracy of LARA make it applicable for structural damage detection on bridges using inclinometers.
