Liquid–liquid phase‐separated biomolecular systems are increasingly recognized as key components in the intracellular milieu where they provide spatial organization to the cytoplasm and the nucleoplasm. The widespread use of phase‐separated systems by nature has given rise to the inspiration of engineering such functional systems in the laboratory. In particular, reversible gelation of liquid–liquid phase‐separated systems could confer functional advantages to the generation of new soft materials. Such gelation processes of biomolecular condensates have been extensively studied due to their links with disease. However, the inverse process, the gel–sol transition, has been less explored. Here, a thermoresponsive gel–sol transition of an extracellular protein in microgel form is explored, resulting in an all‐aqueous liquid–liquid phase‐separated system with high homogeneity. During this gel–sol transition, elongated gelatin microgels are demonstrated to be converted to a spherical geometry due to interfacial tension becoming the dominant energetic contribution as elasticity diminishes. The phase‐separated system is further explored with respect to the diffusion of small particles for drug‐release scenarios. Together, this all‐aqueous system opens up a route toward size‐tunable and monodisperse synthetic biomolecular condensates and controlled liquid–liquid interfaces, offering possibilities for applications in bioengineering and biomedicine.

“…iScience Review printing method that integrates conductive fiber preparation and fiber-to-circuit connection to fabricate PEDOT:PSS fibers has been reported (Figure 4C). The PEDOT:PSS fibers, working as noncontact and portable respiratory sensors, can collect both the distribution and direction of exhaled gas (Wang et al, 2020c). Although electronic fibers can easily realize sensing ability, poor selectivity and anti-interference ability are still huge challenges.…”

Wearable electronics are receiving increasing attention with the advances of human society and technologies. Among various types of wearable electronics, electronic fibers/textiles, which integrate the comfort and appearance of conventional fibers/textiles with the functions of electronic devices, are expected to play important roles in remote health monitoring, disease diagnosis/treatment, and human-machine interface. This article aims to review the recent advances in electronic fibers/textiles, thus providing a comprehensive guiding reference for future work. First, we review the selection of functional materials and fabrication strategies of fiber-shaped electronic devices with emphasis on the newly developed functional materials and technologies. Their applications in sensing, light emitting, energy harvest, and energy storage are discussed. Then, the fabrication strategies and applications of electronic textiles are summarized. Furthermore, the integration of multifunctional electronic textiles and their applications are summarized. Finally, we discuss the existing challenges and propose the future development of electronic fibers/textiles. INTRODUCTIONRecently, development of flexible and wearable electronics has been gradually prominent in our daily life (Park et al., 2018;Trung and Lee, 2016). Ideal wearable electronics possess characteristics of flexibility, light weight, easy to bind with human skin, and tolerating mechanical deformation, to satisfy the requirements of comfort and avoid interfering with normal activities of humans (Zeng et al., 2014). However, traditional electronics with high performance are mostly made of bulky and rigid inorganic materials, such as silicon or gallium arsenide, which are used for fabrication of complex planar circuits (Fan et al., 2008; Kim et al., 2009). The mechanical mismatch between rigid electronics and human skin has immensely prevented electronic devices from conformably attaching on the human body. Therefore, electronic devices are gradually developing toward flexibility and miniaturization to fulfill the requirements of wearing, and have developed from three dimensional (3D) rigid devices to low-dimensional and lightweight flexible devices. Electronics in forms of fibers and textiles, with advantages of good flexibility, light weight, breathability, and easiness of integration with traditional clothes, are one of the ideal form of wearables (Chatterjee et al., 2019).Although fibers have been used in human lives for thousands of years, the history of developing functional and intelligent fibers is not long. Before the emergence of flexible and wearable electronics, optical fibers and metal fibers were the representative functional fibers (Kao and Hockham, 1966;Wardclose and Partidge, 1990). Recently, with the progress of material science and nanotechnology, wearable electronic fibers/ textiles, including 1D fiber-shaped electronic devices (electronic fibers) and 2D/3D electronic textiles, which combine the flexibility and excellent mechanical properties of fib...

“…Novel implanted structures bring exciting characteristics to MCP E-skin, such as, non-contact sensing without direct contact, antidamage, and resistance stability after large angle deformation. It is necessary to keep the resistance unchanged when the flexible sensing module is deformed such as bending, which can ensure the stability of the signal transmission of the intelligent system [46]. We chose the best sample preparation parameters of 100 mg/20 mL (MWCNT/liquid), 2 cm width, and 3 layers.…”

If a person comes into contact with pathogens on public facilities, there is a threat of contact (skin/wound) infections. More urgently, there are also reports about COVID-19 coronavirus contact infection, which once again reminds that contact infection is a very easily overlooked disease exposure route. Herein, we propose an innovative implantation strategy to fabricate a multi-walled carbon nanotube/polyvinyl alcohol (MWCNT/PVA, MCP) interpenetrating interface to achieve flexibility, anti-damage, and non-contact sensing electronic skin (E-skin). Interestingly, the MCP E-skin had a fascinating non-contact sensing function, which can respond to the finger approaching 0–20 mm through the spatial weak field. This non-contact sensing can be applied urgently to human-machine interactions in public facilities to block pathogen. The scratches of the fruit knife did not damage the MCP E-skin, and can resist chemical corrosion after hydrophobic treatment. In addition, the MCP E-skin was developed to real-time monitor the respiratory and cough for exercise detection and disease diagnosis. Notably, the MCP E-skin has great potential for emergency applications in times of infectious disease pandemics. Electronic Supplementary Material Supplementary material (fabrication of MCP E-skin, laser confocal tomography, parameter optimization, mechanical property characterization, finite element simulation, sensing mechanism, signal processing) is available in the online version of this article at 10.1007/s12274-021-3831-z.
