“…Poly-(dimethylsiloxane) (PDMS) composites containing highdielectric-constant (k) ceramic particles (La 0.8 Sr 0.2 CoO 3 , LSCO) are another recent example. 10 The introduction of high-performance materials enhanced the capacitance of pure polymers and improved the output performance of TENGs. A major drawback of the previously mentioned composite systems is that the uniform dispersion of carbon and inorganic additives throughout the entire polymer matrix is essential, and this is not a trivial task.…”

This work reveals the correlation between the performance of triboelectric nanogenerators (TENGs) and the characteristics of deformable solid-state ionic conductors (referred to as ionogels). For this purpose, we modify ionogel characteristics by incorporating additional plasticizers (propylene carbonate) and solid salts (lithium bis(trifluoromethylsulfonyl)imide) into the ionogels. We conclude that the high capacitance of the ionogel is crucial for achieving a high-performance TENG platform. The optimized ionogel-based TENG (i-TENG) exhibits a power density of ∼372.4 mW·m–2 (based on 95 V and 36 mA·m–2 outputs) with outstanding long-term stability over 2 weeks. Additionally, successful demonstrations of wearable nanogenerators are performed by leveraging the high stretchability (up to ∼1000%) and optical transparency (∼90%) of the ionogels. Overall, the results provide insight into the design of deformable ionic conductors for high-performance, reliable, and wearable TENGs.

“…[ 15 ] Nevertheless, fewer efforts have been dedicated to optimizing the long‐term durability of TENG materials. For example, TENG based on polymers such as PDMS, [ 16 ] PVDF, [ 17 ] and PET [ 17 ] have exhibited low friction, but are thermally unstable, soft in nature, and thus are not a viable option for industrial applications. [ 18 ] A TENG device exhibiting a remarkable thermal, chemical, and electrical stability, low friction coefficient, and electrically insulated would be an ideal material for commercial applications.…”

This work details the triboelectric characteristics of diamond‐like carbon (DLC) film where a proportioned sp3:sp2 bond ratio is engineered through a patented pulsed DC magnetron sputtering process to achieve a durable commercial energy harvesting material. A triboelectric nanogenerator (TENG) is fabricated by creating the triboelectric interface between DLC and PTFE. The presence and synchronization of σ – σ and σ – π bonds between DLC‐PFTE contact surface amplify the electronic cloud overlap between their atoms leading to an enhancement of the triboelectric surface charge density. The inherent hardness and reduced friction achieved through DLC and PTFE respectively prevent the mass transfer, and consequent power loss upon consecutive mechanical contact and achieves a stable electric power output of 141 mW m−2. The DLC durability achieved with PTFE in TENG demonstrates its significant potential as low frequency (1 – 10 Hz) energy harvesting devices and self‐/low‐power electronic devices and sensors. The paper uniquely contributes to a better understanding of the triboelectrification mechanism by insightfully detailing the band‐to‐band transition of electrons between the PTFE and DLC tribo‐interface, as well as discussing gap and frequency limitation of the tribo‐pair on the triboelectric charge yield, storage, transfer, and on the friction layer electric field.
