Abstract

Considerable research has been conducted on the application of functional nano‐fillers to enhance the power generation capabilities of triboelectric nanogenerators (TENGs). However, these additives often exhibit a decrease in output power at higher concentration. Here, a Janus cobalt metal–organic framework‐SEBS (JCMS) membrane is reported as a dual‐purpose dielectric layer capable of efficiently capturing and blocking charges for high‐performance TENGs. The JCMS is produced asymmetrically through gravitational sedimentation, employing spherical CoMOFs within a diluted SEBS solution. Beyond its dual dielectric characteristics, the JCMS showcases exceptional mechanical durability, displaying notable stretchability of up to 475% and remarkable resilience when subjected to diverse mechanical pressures. Consequently, the JCMS‐TENG produces a maximum peak‐to‐peak voltage of 936 V, a current of 42.8 µA, and a power density of 10.89 W m−2 when exposed to an external force of 10 N at a 5 Hz frequency. This investigation highlights the potential of JCMS‐TENGs with unique structures, known for their exceptional energy harvesting capabilities, mechanical strength, and flexibility. Additionally, the promising prospects of easily produced asymmetric structures is emphasized with bifunctionalities for developing efficient and flexible MOFs‐based TENGs. These advancements are well‐suited for self‐powered wearables, rehabilitation devices, and energy harvesters. [ABSTRACT FROM AUTHOR]

Abstract

Regular health checkups are crucial for the identification of problems in connection with acute and chronic diseases. Early detection helps patients prevent disease progression, receive more effective treatment, and improve their overall prognosis and quality of life. In this context, the introduction of cost‐effective, advanced sensor technology for the monitoring of healthcare is an essential and unavoidable approach. The present study proposes a disposable triboelectric nanogenerator (TENG) based sensor for a novel urination condition evaluation methodology that is integrated with an artificial intelligence (AI) algorithm. The disposable TENG sensor is fabricated using chitosan‐covalent organic framework (CS‐NSCoF). The optimized CS‐NSCoF (4%) composite, in contact with fluorinated ethylene propylene (FEP), yields remarkable output performance metrics: a peak‐to‐peak voltage of 132 V, a short‐circuit current of ≈2.38 µA, and an average power density of 10.89 mW m−2 at a load resistance of 200 MΩ. Notably, biocompatibility assessments confirm the non‐toxic nature of the CS‐NSCoF sample in this investigation. [ABSTRACT FROM AUTHOR]
