“…[ 1,2 ] Compared with blood analysis and endoscopy, respiration analysis is a fast, non‐invasive, painless, low‐cost, and convenient approach for early illness diagnosis and real‐time physiological monitoring. [ 3–5 ] Assessment of the diaphragmatic movement during breathing (dash line, Figure ) can provide the early recognition of human diseases like abnormalities apnea, asthma, cardiac arrest, and lung cancer. [ 6,7 ] Furthermore, the obstructive sleep apnea syndrome (SAS), arising from the collapse of the soft tissues at upper respiratory tract, poses a huge hazard in human health and safety and the potential causes for various diseases, such as diabetes, hypertension, stroke and even nocturnal death.…”

In mammals, physiological respiration involves respiratory cycles of inhaled and exhaled breaths, which has traditionally been an underutilized resource potentially encompassing a wealth of physiologically relevant information as well as clues to potential diseases. Recently, triboelectric nanogenerators (TENGs) have been widely adopted for self‐powered respiration monitoring owing to their compelling features, such as decent biocompatibility, wearing comfort, low‐cost, and high sensitivity to respiration activities in the aspect of low frequency and slight amplitude body motions. Physiological respiration behaviors and exhaled chemical regents can be precisely and continuously monitored by TENG‐based respiration sensors for personalized health care. This article presents an overview of TENG enabled self‐powered respiration monitoring, with a focus on the working principle, sensing materials, functional structures, and related applications in both physical respiration motion detection and chemical breath analysis. Concepts and approaches for acquisition of physical information associated with respiratory rate and depth are covered in the first part. Then the sensing mechanism, theoretical modeling, and applications related to detection of chemicals released from breathing gases are systemically summarized. Finally, the opportunities and challenges of triboelectric effect enabled self‐powered respiration monitoring are comprehensively discussed and criticized.

“…However, concerns about electromagnetic interference (EMI) issues also arise, such as data loss and misinterpretation because of electromagnetic induction effects [6][7][8][9]. The potential adverse effects of electromagnetic radiation on human health cannot be ignored [10], especially with the advent of the rapid commercialization of emerging 5G wireless devices that will be deployed everywhere around us [11][12][13][14].Consequently, high-performance and durable EMI shielding materials are in high demand and have placed additional requirements on fabrication (e.g., easy processability), performance (e.g., stability and durability for devices working in harsh environments), wearability (e.g., high air permeability and lightweight), etc. Consequently, a wide range of building-block materials, including nanometal products (nanoparticles or nanowires) [15][16][17], nanocarbon products (carbon nanotubes [18,19] or graphene [9]), MXene [20], conductive polymers [21,22], ferrite [23], and their hybrids [24][25][26], have been investigated for use in the form of a coating on a supporting substrate (e.g., a fabric) for EMI shielding.…”

Durable electromagnetic interference (EMI) shielding is highly desired, as electromagnetic pollution is a great concern for electronics’ stable performance and human health. Although a superhydrophobic surface can extend the service lifespan of EMI shielding materials, degradation of its protection capability and insufficient self-healing are troublesome issues due to unavoidable physical/chemical damages under long-term application conditions. Here, we report, for the first time, an instantaneously self-healing approach via microwave heating to achieve durable shielding performance. First, a hydrophobic 1H,1H,2H,2H-perfluorooctyltriethoxysilane (POTS) layer was coated on a polypyrrole (PPy)-modified fabric (PPy@POTS), enabling protection against the invasion of water, salt solution, and corrosive acidic and basic solutions. Moreover, after being damaged, the POTS layer can, for the first time, be instantaneously self-healed via microwave heating for a very short time, i.e., 4 s, benefiting from the intense thermal energy generated by PPy under electromagnetic wave radiation. This self-healing ability is also repeatable even after intentionally severe plasma etching, which highlights the great potential to achieve robust and durable EMI shielding applications. Significantly, this approach can be extended to other EMI shielding materials where heat is a triggering stimulus for healing thin protection layers. We envision that this work could provide insights into fabricating EMI shielding materials with durable performance for portable and wearable devices, as well as for human health care."Image missing"

“…Because self-powered sensors can use their own energy to provide information, they have lower power consumption and only need two wires for signal transmission, and can even can realize signal transmission with only one wire. Therefore, self-powered sensors have been widely investigated [ 15 , 16 , 17 ].…”

“…Crystal materials have limitations such as high production cost, sensitivity to moisture, and difficulty in obtaining consistent orientations. However, polycrystalline ceramic materials are easy to process [ 17 ], and have relatively low manufacturing cost, higher sensitivity than crystals [ 18 ], and a wide range of applications. In recent years, structures such as nanofibers [ 19 ], nanowires [ 20 ], nanoparticles [ 21 ], nanocubes [ 22 ], and nanorods [ 23 ] have been used in piezoelectric material structures.…”

Sensors are an important part of the organization required for robots to perceive the external environment. Self-powered sensors can be used to implement energy-saving strategies in robots and reduce their power consumption, owing to their low-power consumption characteristics. The triboelectric nanogenerator (TENG) and piezoelectric transducer (PE) are important implementations of self-powered sensors. Hybrid sensors combine the advantages of the PE and TENG to achieve higher sensitivity, wider measurement range, and better output characteristics. This paper summarizes the principles and research status of pressure sensors, displacement sensors, and three-dimensional (3D) acceleration sensors based on the self-powered TENG, PE, and hybrid sensors. Additionally, the basic working principles of the PE and TENG are introduced, and the challenges and problems in the development of PE, TENG, and hybrid sensors in the robotics field are discussed with regard to the principles of the self-powered pressure sensors, displacement sensors, and 3D acceleration sensors applied to robots.
