“…A recent study [ 41 ] has shown that optimizing the location and distribution of the load provides the highest sensitivity. Figure 5 shows the calculated resonance frequency f 0 of the Fe-Co/Ni clad plates where the distance between the center of the proof mass and the fixed end is a = 0.5, 9.5, 19, 28.5, and 37.5 mm.…”

The severe acute respiratory syndrome coronavirus (SARS-CoV-2) has spread rapidly around the world. In order to prevent the spread of infection, city blockades and immigration restrictions have been introduced in each country, but these measures have a severe serious impact on the economy. This paper examines the possibility of both harvesting vibration energy and detecting mass by using a magnetostrictive alloy. Few efforts have been made to develop new magnetostrictive biosensor materials. Therefore, we propose magnetostrictive Fe-Co/Ni clad steel vibration energy harvesters with mass detection, and we numerically and experimentally discuss the effect of the proof mass weight on the frequency shift and output voltage induced by bending vibration. The results reveal that the frequency and output voltage decrease significantly as the mass increases, indicating that the energy harvesting device is capable of mass detection. In the future, device miniaturization and the possibility of virus detection will be considered.

“…Each sample was tested at least four times, and the average value was recorded. The load-displacement curve was observed to be different because of the influence of transverse piezoelectricity on the material, and this influence corresponds to Equations ( 4) and (7). According to the load-deflection diagram, Young's modulus, E c 11 , of the CFRP/KNN/EP composite material can be calculated from Equation (14).…”

“…The piezoelectric effect is a phenomenon in which a voltage is generated on the basis of the strain produced when mechanical loads are applied to quartz or specific types of ceramics. The piezoelectric effect has been used to develop various sensors [3][4][5][6][7][8]. Hence, it has recently emerged as a potential material for vibration energy harvesting that can recover electric power from unused energy such as vibration [9][10][11][12][13][14][15][16][17].…”

Wireless sensor networks are the future development direction for realizing an Internet of Things society and have been applied in bridges, buildings, spacecraft, and other areas. Nevertheless, with application expansion, the requirements for material performance also increase. Although the development of carbon-fiber-reinforced polymer (CFRP) to achieve these functions is challenging, it has attracted attention because of its excellent performance. This study combined the CFRP electrode with epoxy resin containing potassium sodium niobate piezoelectric nanoparticles and successfully polarized the composite sample. Furthermore, a three-point bending method was applied to compare the bending behavior of the samples. The peak output voltage produced by the maximum bending stress of 98.4 MPa was estimated to be 0.51 mV. Additionally, a conversion efficiency of 0.01546% was obtained. The results showed that the piezoelectric resin with CFRPs as the electrode exhibited stress self-inductance characteristics. This study is expected to be applied in manufacturing self-sensing piezoelectric resin/CFRP composite materials, paving the way for developing stable and efficient self-sensing structures and applications.

populations. Moreover, with the advent of the novel coronavirus disease (COVID-19), significant investment in medical resources is required. Under the umbrella of the global COVID-19 pandemic, the use of biosensors in healthcare and online medical care are becoming ubiquitous, which represent methods that can be used to detect signs from the human body for further health analysis. Furthermore, the internet of things (IoT) technology in healthcare is a method by which biosensorembedded objects can be worn on the human body in everyday life that continuously measure and digitize health information without any burden to the wearer. [1] Recently, various biometric technologies have been developed, wearable devices such as smart watches, invasive biodevices, and devices that sense the everyday surrounding environment of the wearer. Medical data can be collected using such devices, which can then be further analyzed by artificial intelligence (AI). These data can then be used for health promotion, prevention of disease, and early disease diagnosis. Moreover, with the advent of COVID-19, healthcare IoT (HIoT) technology has become extremely important. [2] In terms of the individual, when a mask is constantly worn it may cause lung damage to the user. Therefore, the HIoT would make a significant contribution in this case to offer forewarning about the situations of the lungs As society advances, the shift from passive medical care to health management and preventive medical care has become an important issue, with the realization of wearable monitors becoming desirable. In light of the COVID-19 pandemic, the number of patients who are in urgent need of the monitoring of biological information is increasing. This review focuses on piezoelectric materials and composites that convert kinetic energy into electrical energy to realize self-powered wearable monitoring sensors, outlining the recent research activity on sensors for use in healthcare monitoring. First, a general description of the principles of piezoelectric monitoring sensors is given. Next, the development status of piezoelectric materials and composites aimed at the application of detecting tiny motions of the human body is introduced, and then the research trends on the detection of larger human body movements are highlighted. Finally, after presenting the performance of current piezoelectric sensors and future research guidelines for developing multifunctional systems in the post COVID-19 era, the achievements are summarized. Overall, this review will provide guidance to researchers who are seeking to design and develop highly sensitive self-powered piezoelectric sensors that monitor human motion and physiological signals.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/admt.202200318.
