“…[ 22 ] It requires a good design configuration of the floating harvesting/sensing device such that it can closely synchronize with the arbitrary nature of the water waves. Considering the arbitrary wave nature, various designs have been reported such as spherical‐shaped, [ 34 ] tubular‐shaped, [ 35 ] pendulum‐shaped, [ 36 ] ellipsoidal‐shaped (providing a path similar to the cycloid), [ 22,16 ] and many more. Although the spherical‐shaped devices can closely synchronize with the random water waves in 3D directions, the sharp curvature of the sphere restricts the movement of the inside ball magnet thus limiting the device's performance.…”

healthy swimming environment. Among the vital features of pool water, water pH, free Cl − contents, hardness, water conductivity, and water temperature are most critical for maintaining a healthy and safe swimming environment. [1] Free Cl − is used to attack invading contaminants in water. [2] However, insufficient content of free Cl − makes pool water susceptible to a variety of undesired effects from the born algae and becomes a harbor for water-borne diseases (such as diarrhea, E. coli, cryptosporidium, hepatitis, and skin infections) which may develop from the dispersed biological matters from animals such as body sweat, makeup, body oils, and urine (including pets). [3] Therefore, the pool needs enough free Cl − to kill unwanted pathogens and contaminants. But the

“…The PPSS mode refers to the use of additional energy harvesting devices to power sensors. Commonly used energy harvesting principles include piezoelectric, [11] triboelectricity, [12] thermoelectric, [13] electromagnetic, [14] photoelectricity, [15] biofuels, [16] electrets, [17] and so on. The APGS mode means that the generators work simultaneously as sensing elements.…”

Energy‐autonomous wearable human activity monitoring is imperative for daily healthcare, benefiting from long‐term sustainable uses. Herein, a fully self‐powered wearable system, enabling real‐time monitoring and assessments of human multimodal health parameters including knee joint movement, metabolic energy, locomotion speed, and skin temperature, which are fully self‐powered by highly‐efficient flexible thermoelectric generators (f‐TEGs) is proposed and developed. The wearable system is composed of f‐TEGs, fabric strain sensors, ultra‐low‐power edge computing, and Bluetooth. The f‐TEGs worn on the leg not only harvest energy from body heat and supply power sustainably for the whole monitoring system, but also serve as zero‐power motion sensors to detect limb movement and skin temperature. The fabric strain sensor made by printing PEDOT: PSS on pre‐stretched nylon fiber‐wrapped rubber band enables high‐fidelity and ultralow‐power measurements on highly‐dynamic knee movements. Edge computing is elaborately designed to estimate multimodal health parameters including time‐varying metabolic energy in real‐time, which are wirelessly transmitted via Bluetooth. The whole monitoring system is operated automatically and intelligently, works sustainably in both static and dynamic states, and is fully self‐powered by the f‐TEGs.
