Introduction

Soft bio-integrated multifunctional devices have revolutionized the field of wearable electronics, enabling seamless integration of electronics with the human body. These devices offer numerous possibilities for healthcare monitoring, diagnostics, and therapeutic interventions. However, their successful integration requires materials that possess both mechanical flexibility and electrical conductivity. Stretchable conducting nanomembranes have emerged as a promising solution to address this challenge. These nanomembranes exhibit exceptional mechanical stretchability, conformability, and robust electrical conductivity, making them ideal candidates for soft bio-integrated devices [1]. The development of stretchable conducting nanomembranes involves careful selection of materials and fabrication techniques. Various nanomaterials, such as carbon nanotubes, graphene, and conductive polymers, have been explored to achieve the desired electrical conductivity and mechanical properties. Additionally, fabrication methods such as layer-by-layer assembly, solution casting, and electro spinning have been employed to create nanomembranes with controlled thickness and surface morphology. Functionalization strategies, including surface modification and incorporation of bioactive molecules, further enhance the biocompatibility and functionality of these nanomembranes [2].

The integration of stretchable conducting nanomembranes into soft biointegrated multifunctional devices offers exciting opportunities in different areas. In biosensing applications, these devices enable real-time monitoring of biological signals and analyte detection. The stretchability of nanomembranes allows for intimate contact with the skin or organs, facilitating accurate and noninvasive sensing. In drug delivery systems, nanomembranes provide controlled release and targeted delivery of therapeutics, improving treatment efficacy and patient comfort. Moreover, the incorporation of nanomembranes into humanmachine interfaces enables seamless interaction between electronics and the human body, opening up possibilities for advanced prosthetics and augmented reality applications [3].

Literature Review

The improvement of stretchable leading nanomembranes has arisen as a huge area of exploration in the field of delicate bio-coordinated multifunctional gadgets. Unique properties like electrical conductivity and mechanical flexibility make these nanomembranes ideal for seamless integration with biological systems. Stretchable conducting nanomembranes and their applications in soft bio-integrated devices are the focus of this literature review, which provides an overview of the most important findings and advancements in the field. The selection of appropriate nanomaterials and the development of appropriate fabrication methods are necessary for the production of stretchable conducting nanomembranes. Due to their outstanding electrical and mechanical properties, Carbon Nanotubes (CNTs), graphene, conductive polymers, and their composites have been the subject of extensive research. Nanomembranes have been made using a variety of techniques, including electro spinning, solution casting, layerby- layer assembly, and controlled thickness, surface morphology, and alignment. In order to tailor the mechanical properties and electrical conductivity of the nanomembranes to meet the requirements of soft bio-integrated devices, the selection of nanomaterials and fabrication methods is crucial [4,5].

To improve stretchable conducting nanomembranes' biocompatibility, stability, and functionality, functionalization strategies have been investigated. Biofunctionalization, Self-Assembled Monolayers (SAMs), and polymer coatings are examples of surface modifications used to reduce fouling and improve biocompatibility. The incorporation of bioactive molecules, such as proteins, enzymes, and antibodies, onto the nanomembranes enhances their functionality in biosensing and biomedical applications by enabling specific recognition and interaction with biological targets. Numerous applications in a variety of fields have resulted from the incorporation of stretchable conducting nanomembranes into soft bio-integrated devices. These devices make it possible to monitor physiological signals like heart rate, glucose levels, and muscle activity in real time in biosensing. The nanomembranes' conformability and mechanical flexibility permit close contact with the skin, ensuring reliable signal detection. Advanced human-machine interfaces, such as prosthetics, augmented reality devices, and haptic feedback systems, can also be developed by incorporating stretchable conducting nanomembranes into wearable electronic devices.

Stretchable conducting nanomembranes offer opportunities for controlled release and targeted therapeutic delivery in the field of drug delivery. Drug release can be precise and localized by incorporating drug-loaded nanoparticles or microcapsules into the nanomembranes. These nanomembranes can be used in regenerative medicine, tissue engineering, and wound healing, among other biomedical fields. Stretchable conducting nanomembranes have made significant progress, but there are still a few obstacles to overcome and new directions to take. For the nanomembranes to be put to use in real-world situations, it is essential to improve their mechanical durability and long-term stability. For commercialization, it is also necessary to scale up the fabrication methods so that consistent-property large-area nanomembranes can be produced.

Discussion

The field of soft bio-integrated multifunctional devices has been transformed by the creation of stretchable conducting nanomembranes, which have made it possible to seamlessly integrate electronics with biological systems. The key aspects and implications of stretchable conducting nanomembranes for enabling such devices are examined in this discussion. The remarkable mechanical adaptability of stretchable conducting nanomembranes is one of their primary advantages. Without affecting their electrical conductivity, these nanomembranes are able to conform to complex and irregular surfaces, including the human body. Because it makes it possible for bio-integrated devices to be worn in a way that is both comfortable and unobtrusive, this property is crucial for the successful integration of electronics with biological systems. The devices' mechanical flexibility mimics the natural flexibility of the human body and ensures that they can withstand stretching, bending, and twisting motions.

Another crucial aspect for soft bio-integrated devices is stretchable conducting nanomembranes' electrical conductivity. Nanomaterials like carbon nanotubes, graphene, and conductive polymers maintain mechanical flexibility while still providing high electrical conductivity. The devices can effectively transmit electrical signals thanks to these nanomaterials' exceptional electron transport properties. In bio-integrated devices, accurate sensing, actuation, and data communication depend on this conductivity. The properties of stretchable conducting nanomembranes can be significantly altered by the fabrication methods used. Nanomembranes can be precisely controlled in terms of thickness, morphology, and alignment using electro spinning, solution casting, and layer-by-layer assembly methods. Optimizing the interface between the nanomembranes and biological systems and achieving the desired mechanical and electrical properties require this control [6].

Additionally, surface functionalization techniques like biofunctionalization and polymer coatings improve the biocompatibility and stability of the nanomembranes, making it easier for them to adapt to biological environments. Advanced human-machine interfaces are also possible because stretchable conducting nanomembranes can be seamlessly integrated into soft bio-integrated devices. By permitting direct interaction between the prosthesis and the user's neural signals, these devices, for instance, in the field of prosthetics, can provide enhanced functionality, comfort, and control.

Conclusion

For soft bio-integrated multifunctional devices, the development of stretchable conducting nanomembranes has opened up exciting possibilities. These nanomembranes' mechanical flexibility and electrical conductivity make it possible to seamlessly integrate with biological systems, paving the way for advancements in biosensing, drug delivery, and interfaces between humans and machines. Stretchable conducting nanomembranes' mechanical durability and scalability should be the primary focus of future research, paving the way for their widespread application in biomedical devices and wearable electronics. In a similar vein, stretchable nanomembranes make it easier to create wearable displays for augmented reality applications that fit the wearer's body and provide an immersive and comfortable user experience.
