“…However, similarly, the SE A exhibits a trend of initial increase followed by a decrease, although not as pronounced as the change in reflection efficiency. Finally, we compared the electromagnetic shielding performance of the SCCF to some flexible composite conductive materials for wearable electronics, [64][65][66][67][68][69] and our SCCF performs exceptionally well in electromagnetic shielding. In the SCCF, the dominant component is PEDOT:PSS, and it is widely recognized that absorption plays a major role in conductive polymers compared to metals.…”

“…[3][4][5] As a result of their diverse range of applications, including electronic skin, 6 human-machine interaction, 7 and robotic arms, 8 extensive research has been devoted to the field of flexible tactile sensors. These sensors can be classified into four categories based on their principles: resistive, 9 capacitive, 10 piezoelectric, 11 and triboelectric. 12,13 However, the electrodes of these tactile sensors are typically made of metal 14 or metal coated plastic 15 or composite conductive materials.…”

“…Meanwhile, their modifiable functional groups can give them strong adhesion. 9,[17][18][19][20] Nevertheless, the mechanical and electrical properties of hydrogels are unavoidably degraded as they undergo dehydration, which raises a significant problem. Due to the evaporation of water, alternative methodologies are to use gels without water.…”

Hydrogels are polymeric materials that possess a set of characteristics meeting various requirements of an ideal wound dressing, making them promising for wound care. These features include, among others, the ability to absorb and retain large amounts of water and the capacity to closely mimic native structures, such as the extracellular matrix, facilitating various cellular processes like proliferation and differentiation. The polymers used in hydrogel formulations exhibit a broad spectrum of properties, allowing them to be classified into two main categories: natural polymers like collagen and chitosan, and synthetic polymers such as polyurethane and polyethylene glycol. This review offers a comprehensive overview and critical analysis of the key polymers that can constitute hydrogels, beginning with a brief contextualization of the polymers. It delves into their function, origin, and chemical structure, highlighting key sources of extraction and obtaining. Additionally, this review encompasses the main intrinsic properties of these polymers and their roles in the wound healing process, accompanied, whenever available, by explanations of the underlying mechanisms of action. It also addresses limitations and describes some studies on the effectiveness of isolated polymers in promoting skin regeneration and wound healing. Subsequently, we briefly discuss some application strategies of hydrogels derived from their intrinsic potential to promote the wound healing process. This can be achieved due to their role in the stimulation of angiogenesis, for example, or through the incorporation of substances like growth factors or drugs, such as antimicrobials, imparting new properties to the hydrogels. In addition to substance incorporation, the potential of hydrogels is also related to their ability to serve as a three-dimensional matrix for cell culture, whether it involves loading cells into the hydrogel or recruiting cells to the wound site, where they proliferate on the scaffold to form new tissue. The latter strategy presupposes the incorporation of biosensors into the hydrogel for real-time monitoring of wound conditions, such as temperature and pH. Future prospects are then ultimately addressed. As far as we are aware, this manuscript represents the first comprehensive approach that brings together and critically analyzes fundamental aspects of both natural and synthetic polymers constituting hydrogels in the context of cutaneous wound healing. It will serve as a foundational point for future studies, aiming to contribute to the development of an effective and environmentally friendly dressing for wounds.

“…The functional groups in gelatin allow robust interactions with a range of nanofillers, increasing interfacial bonding and dispersion and ultimately enhancing the overall performance of the nanocomposite materials . The unique combination of biocompatibility, bioactivity, tunability, and environmental friendliness makes gelatin a preferable polymer in different fields, from tissue engineering and drug delivery to electronics and optical materials. − Gelatin is usually extracted from mammal skin and bones; however, several diseases, e.g., bovine spongiform encephalopathy (mad-cow), tooth-and-mouth disease, and swine-influenza, have emerged from mammalian gelatin. Therefore, fish gelatin (FG) has drawn significant attention as an alternative .…”

This study presents a comprehensive analysis of a ternary nanocomposite of carbon nanotube (CNT) and ZnOnanorod (ZNR)-reinforced fish gelatin (FG), assessing its potential applications for wearable smart technology. The nanocomposite is prepared by the solution casting method by varying concentrations of nanofillers (0.00, 0.20, 0.25, and 0.30%), where individual nanofillers are taken in the same concentration and analyzed by different characterization techniques to comprehend their interaction. Regarding nanofillers, nearly perfect graphitized CNTs of minimum defects and ZNRs with a high degree of crystallinity with an interlayer spacing of 0.233 nm are used and encapsulation of the nanofillers by the FG matrix is observed. The crystallinity is increased with the initial incorporation of nanofillers but interestingly decreases with higher concentrations. Amide bands are identified with peak shifting, suggesting enhanced interactions between nanofillers and the FG matrix. With the increase in nanofiller concentration, the effects on thermal stability of the nanocomposites and shifting in glass transition and melting temperatures are also investigated. The incorporation of nanofillers significantly improved the mechanical and electrical properties. This study would help to understand the influence of nanofillers in tailoring the properties of nanocomposite, offering opportunities to tune their properties and explore applications in wearable smart technology.
