Triboelectric nanogenerators (TENGs) are an emerging class of energy harvesting devices with considerable potential across diverse applications, including wearable electronic and self-powered sensors. However, sustained contact, friction, incidental scratches during operation can lead to a deterioration in the electrical output performance TENG, thereby reducing its overall service life. To address this issue, we developed self-healing elastomer by incorporating disulfide bonds metal coordination into polyurethane (PU) chain. The resulting demonstrated exceptional toughness, high value 85 kJ m–3 impressive efficiency 85.5%. Specifically, TENG based on that PU generated short circuit current 12 μA, open voltage 120 V, transfer charge 38.5 nC within 2 cm × area, operating contact-separation mode. With external resistance 20 MΩ, achieved power density 2.1 W m–2. Notably, even after self-healing, was maintained at 95% undamaged device. Finally, employed construct noncontact sensing system be applied monitor human motion accurately. This research may expand application prospects materials future human–computer interaction fields.

Abstract Respiratory diseases are currently monitored through traditional pulmonary function tests, such as spirometry. However, the restrictions of these procedures, particularly in context COVID‐19 pandemic, have underscored need for alternative approaches to respiratory health assessment. Wearable devices emerged a promising solution, providing continuous data collection, and overcoming limitations posed by conventional methods. This review explores multifaceted field wearable monitoring, presenting most common sensing technologies applied ventilation, their constituent materials, fabrication techniques, diverse morphologies enhance sensor performance. The role machine learning algorithms ethical sharing is highlighted, contributing forthcoming patient‐centered healthcare landscape. Ultimately, importance validation calibration protocols underlined. In anticipation evolving needs, this in‐depth study addresses current challenges monitoring while laying robust foundation personalized, connected, ethically sound future care.

The generation of waste materials is an inevitable byproduct various human and ecological activities. Inadequate management can have detrimental effects on the environment, leading to long-lasting harm both living organisms broader ecosystem. A waste-to-sustainable energy concept based TENGs a new research technology added other green renewable technologies. It highly efficient in using wide range convert chaotic environmental energies into electricity for intelligent applications. In this review, are classified non-degradable (plastic waste), bio-degradable waste, combined waste. These types showed great capability converting low frequency wasted mechanical electrical pulses applications healthcare, IoT wireless technologies smart buildings. worth noting that utilizing plastic as tribo-pairs doe does not compromise performance efficiency fabricated TENGs. For instance, non-modified X-ray film has been used positive tribo-layer force sensing application. TENG with maximum power density 8.78 W/m2 (Navaneeth et al., 2023a,b) which comparable prepared tribo-materials. We propose promising sustainable alternative upcycling materials.

Triboelectric nanogenerators (TENGs) developed from eco-friendly natural materials rather than traditional electronic are more favorable for biocompatible applications and use in sustainable life-cycle analysis. Silk fibroin (SF) has emerged as an abundant biomaterial that shows great potential the preparation of TENGs. Silk-based triboelectric (SF-TENGs) have green energy harvesting properties, environmentally friendly, biocompatible, not fully present conventional TENGs, important next generation self-powered devices. In this review, latest progress SF-TENGs, including their applied materials, structural manufacturing processes, application scenarios, is discussed. These SF-TENGs show emerging well smart living medical assistance. addition, value been further explored, possibility main challenges expanding applying to field microneedles (MNs)
