“…These electrodes exhibit prolonged reusability, excellent biocompatibility, and suitability for athletic activities. Carbon materials are frequently integrated with fabrics through brush coating, heat treatment, and impregnation–drying techniques to deposit carbon onto fabric substrates. − Gogurla et al utilized a printing technique to pattern carbon nanotubes (CNTs) onto silk fabric, yielding a CNT-infused silk fabric exhibiting notable electrical power density (0.7 mW cm –2 ) and remarkable pressure sensitivity of 0.019 kPa –1 upon skin contact. Ma et al employed a screen-printing technique to deposit a textile-based electrode on cotton fabric, incorporating carbon black and regenerated silk gel.…”

“…[ 4 , 5 , 6 , 7 ] In addition, cost‐effective as well as eco‐ and biofriendly fabrication processes are important to produce reliable natural polymer‐TENG devices. [ 8 , 9 ] Therefore, natural polymers, including deoxyribonucleic acid (DNA), silk protein, cellulose, whey protein, gelatin, and egg white, are gaining considerable interest as potential materials for natural polymer‐TENGs. Additionally, efforts are being made to develop suitable fabrication processes for natural polymer‐TENGs because of their inherent biofriendly traits, which are beneficial for various applications.…”

Natural polymer‐based and self‐powered bioelectronic devices are attracting attention owing to an increased interest in human health monitoring and human–machine interfaces. However, obtaining both high efficiency and multifunctionality from a single natural polymer‐based bioelectronics platform is still challenging. Here, molybdenum disulfide (MoS2) nanoparticle‐ and carbon quantum dot (CQDs)‐incorporated deoxyribonucleic acid (DNA) nanocomposites are reported for energy harvesting, motion sensing, and charge storing. With nanomaterial‐based electrodes, the MoS2‐CQD‐DNA nanocomposite exhibits a high triboelectric open‐circuit voltage of 1.6 kV (average) and an output power density of 275 mW cm−2, which is sufficient for turning on hundred light‐emitting diodes and for a highly sensitive motion sensing. Notably, the triboelectric performance can be tuned by external stimuli (light and thermal energy). Thermal and photon energy absorptions by the nanocomposite generate additional charges, resulting in an enhanced triboelectric performance. The MoS2‐CQD‐DNA nanocomposite can also be applied as a capacitor material. Based on the obtained electronic properties, such as capacitances, dielectric constants, work functions, and bandgaps, it is possible that the charges generated by the MoS2‐CQD‐DNA triboelectric nanogenerator can be stored in the MoS2‐CQD‐DNA capacitor. A new way is presented here to expand the application area of self‐powered devices in wearable and implantable electronics.
