The evolution of artificial intelligence things (AIoT) drastically facilitates the development a smart city via comprehensive perception and seamless communication. As foundation, various AIoT nodes are experiencing low integration poor sustainability issues. Herein, cubic-designed intelligent piezoelectric node iCUPE is presented, which integrates high-performance energy harvesting self-powered sensing module micromachined lead zirconate titanate (PZT) thick-film-based high-frequency (HF)-piezoelectric generator (PEG) poly(vinylidene fluoride-co-trifluoroethylene) (P(VDF-TrFE)) nanofiber thin-film-based low-frequency (LF)-PEGs, respectively. LF-PEG HF-PEG with specific frequency up-conversion (FUC) mechanism ensures continuous power supply over wide range 10-46 Hz, record high density 17 mW/cm3 at 1 g acceleration. cubic design allows for orthogonal placement three FUC-PEGs to ensure response vibrational sources from different directions. triaxial sensor (TPS) combined machine learning (ML) assisted units by using LF-PEGs achieve high-precision multifunctional vibration recognition resolutions 0.01 g, 2° acceleration, frequency, tilting angle, respectively, providing accuracy 98%-100%. This work proves feasibility developing ML-based accelerometer gyroscope functions resonant frequencies. proposed sustainable highly scalable explore capabilities under diverse environments, essential implementation.

Abstract As the most extensive natural energy on earth, ocean wave is regarded as a difficult to be fully and efficiently utilized because of its low frequency multi‐direction movement. Herein, versatile blue triboelectric nanogenerator (VBE‐TENG) fabricated by using dual‐mode output terminals with charge excitation strategy reported, which can harvest varying water‐wave effectively. Benefiting from rolling ball specific track compression rebound characteristics spring sheet steel, carrier driven along path through random energy, then converted into electricity VBE‐TENG. A high peak power 34.3 mW obtained, 2.5 times much that current highest record based device unit in TENG. In addition, TENG light 256 LEDs continuously commercial electronic devices environments. The average voltage contact‐separation virtual signal via Labview software provide height monitoring self‐powered sensing system. This work provides new approach toward practical applications.

Abstract In metaverse, a digital‐twin smart home is vital platform for immersive communication between the physical and virtual world. Triboelectric nanogenerators (TENGs) sensors contribute substantially to providing smart‐home monitoring. However, TENG deployment hindered by its unstable output under environment changes. Herein, we develop using robust all‐TENG based information mat (InfoMat), which consists of an in‐home array entry mat. The interdigital electrodes design allows environment‐insensitive ratiometric readout from cancel commonly experienced environmental variations. Arbitrary position sensing also achieved because interval arrangement pixels. Concurrently, two‐channel generates multi‐modality aid 10‐user identification accuracy increase 93% 99% compared one‐channel case. Furthermore, visualized real‐time projecting in reality, including access authorization, position, walking trajectory, dynamic activities/sports, so on. image

Triboelectric nanogenerators (TENGs) can harvest various forms of mechanical energy from the surrounding environment and convert them into electrical efficiently. Harvesting wind by TENG could be an ideal way to achieve self-powered sensing systems. Herein, a novel calliopsis-inspired biomimetic (C-TENG) was designed for harvesting wind-parameter sensor. The open-circuit voltage (Voc) short-circuit current (Isc) one unit C-TENG reach 61.7 V 0.34μA under speed 15 m/s at frequency 5 Hz, peak output power is 11.57 mW/m2 load resistance 100 MΩ. This not only collects effectively but also utilized detect direction as In this study, we demonstrate type contact-separation mode in calliopsis structure promote sensors meteorological monitoring, agricultural production, nautical industry.
