This article explores the importance of wearable and remote technologies in healthcare. The focus highlights its potential in continuous monitoring, examines the specificity of the issue, and offers a view of proactive healthcare. Our research describes a wide range of device types and scientific methodologies, starting from traditional chest belts to their modern alternatives and cutting-edge bioamplifiers that distinguish breathing from chest impedance variations. We also investigated innovative technologies such as the monitoring of thorax micromovements based on the principles of seismocardiography, ballistocardiography, remote camera recordings, deployment of integrated optical fibers, or extraction of respiration from cardiovascular variables. Our review is extended to include acoustic methods and breath and blood gas analysis, providing a comprehensive overview of different approaches to respiratory monitoring. The topic of monitoring respiration with wearable and remote electronics is currently the center of attention of researchers, which is also reflected by the growing number of publications. In our manuscript, we offer an overview of the most interesting ones.

“…Flow-measuring designs include turbine sensors, hot-wire anemometers, and ultrasonic flowmeters. [10][11][12][13] While many of these architectures have been validated, there are advantages and disadvantages to a given sensing mechanism. For example, ultrasonic and hotwire anemometry flow detection are generally costly and require complex calibration.…”

In this work, a portable venturi tube capable of measuring bidirectional respiratory flow is developed and correlated the measurements to pulmonary function. Pressure signals are transduced using flexible and compressible capacitive foam sensors embedded into the wall of the device. In this configuration, the sensors are able to provide differential pressure readings, from which the airflow rate passing through the tube could be extrapolated. Utilizing the venturi effect, the geometry of the spirometer tube is designed through finite element analysis to measure respiratory airflow during inhalation and exhalation. The device tube is 3D‐printed and used to measure tidal breathing and deep breathing, along with peak expiratory flow rates, on a healthy individual. This spirometer design allows for easy‐to‐use point‐of‐care diagnoses and has the potential to improve the care of respiratory illnesses.

lithium-ion batteries, such as low life, serious pollution, and low safety, have always plagued the development of intelligent wearable devices and intelligent devices. If the energy module of smart wearable devices explodes, the apparent harm is conceivable. [10][11][12] Therefore, the development of a safe and lightweight energy source is urgently necessary. Given the rapid development of the integrated circuits (IC) and low power sensors, the power requirement of smart wearable electronic devices has been reduced from mW to µW. [13][14][15] To solve this problem, it is feasible and effective to collect body movement energy and convert it into electric energy to supply power for smart wearable devices. [16,17] Presently, many kinds of equipment designed to collect body energy have been reported. [18][19][20][21] This study is divided into electromagnetic generator, friction generator, and composite generator. The friction generator provides energy for external electrical appliances under the principle of friction charge effect and electrostatic balance effect, where the relative position change of different electronegative materials will produce the change of electric potential. [22] The electromagnetic generator generates power through the induction of current by the change of magnetic field in closed coil. The composite generator is an effective combination of these two kinds of generator. The friction nanogenerator is obviously more suitable to supply power for intelligent wearable equipment because of its safety and lightweight compared with magnetoelectricity and composite generator. The main direction of this research is to improve the output performance of the proposed nanogenerator. This can be achieved by changing the characteristics of materials through mixing, microprocessing, and other methods. [23][24][25][26] Another method is to improve the collection efficiency of environmental energy by changing the structure of devices.Nature has rich scientific principles such as DNA, which is tightly and steadily aligned with base pairs containing genetic information in the form of helical twists. The combination of the corresponding base pairs can form an effective genetic expression. This allows the arrangement of more genetic information and match more genetic information accurately in a smaller space in the nucleus. It guarantees the richness and security of information. The relative friction layer and electrode Collecting energy from body movements to supply power for equipment is an important method to rapidly develop wearable intelligent equipment. This method places high requirements, such as being lightweight and stable, on a nanogenerator. Herein, a bioinspired helical triboelectric nanogenerator (BH-TENG) that realizes energy acquisition through the intensity and frequency of body movement is designed based on the helical structure of DNA. The helical structure facilitates more contact areas and provides increased stability to complete the power generation process than the simple structure with pl...
