Abstract With the development of autonomous/smart technologies and Internet Things (IoT), tremendous wireless sensor nodes (WSNs) are great importance to realize intelligent mechanical engineering, which is significant in industrial social fields. However, current power supply methods, cable battery for instance, face challenges such as layout difficulties, high cost, short life, environmental pollution. Meanwhile, vibration ubiquitous machinery, vehicles, structures, etc., but has been regarded an unwanted by‐product wasted most cases. Therefore, it crucial harvest energy achieve situ these WSNs. As a recent conversion technology, triboelectric nanogenerator (TENG) particularly good at harvesting broadband, weak, irregular energy, provides feasible scheme In this review, achievements (VEH) related engineering based on TENG systematically reviewed from perspective contact–separation (C‐S) freestanding modes. Finally, existing forthcoming orientation VEH discussed depth, will be conducive future era IoT.

Hybrid Piezoelectric/Triboelectric Wearable Nanogenerator Based on Stretchable PVDF–PDMS Composite Films

ACS Applied Materials & Interfaces, Год журнала: 2024, Номер 16(5), С. 6239 - 6249

Hybrid piezoelectric/triboelectric nanogenerators combine the merits of piezoelectric (PENGs) and triboelectric (TENGs), possessing enhanced electrical output sensitivity. However, structures majority hybrid are rather complex in integrating both functions, limiting their practical application wearable electronics. Herein, we propose to construct a nanogenerator (PT-NG) with simple structure based on composite film simultaneously achieve coupling charge generation triboelectrification improved energy conversion efficiency. The consists electrospun PVDF nanofibers embedded surface PDMS film, which not only forms rough nanomorphology but also provides structural protection by during compressive deformation. results have shown that PT-NG can generate much higher outputs than individual TENG PENG devices. devices exhibit high level mechanical-to-electrical efficiency superior performance charging capacitors functioning as self-powered sensors for detection different signals from finger movement, recognition various gestures, monitoring respiration. More importantly, device possesses an impressive durability, maintaining its layered over 5000 testing cycles without noticing any obvious damage or detachment between layers. Our demonstrated combining substrate is efficient way fabricate highly harvesting intelligent identification health monitoring.
