The deep sea remains the largest uncharted territory on Earth because it’s eternally dark under high pressure and the saltwater is corrosive and conductive. The harsh environment poses great difficulties for the durability of the sensing method and the device. Sea creatures like sharks adopt an elegant way to detect objects by the tiny temperature differences in the seawater medium using their extremely thermo-sensitive thermoelectric sensory organ on the nose. Inspired by shark noses, we designed and developed an elastic, self-healable and extremely sensitive thermal sensor which can identify a temperature difference as low as 0.01 K with a resolution of 0.001 K. The sensor can work reliably in seawater or under a pressure of 110 MPa without any encapsulation. Using the integrated temperature sensor arrays, we have constructed a model of an effective deep water mapping and detection device.

“…Moreover, the use of polymeric binders to enhance electrode mechanical robustness further impairs energy density. Nanomaterials and polymers possessing both robust mechanical flexibility and electrochemical activity are needed. , Electrolytes also face performance trade-off. Conventional liquid (predominantly organic) electrolytes are the most conductive but least stable, leading to high safety risks (due to chemical reactions and leakage) .…”

Humans rely increasingly on sensors to address grand challenges and to improve quality of life in the era of digitalization and big data. For ubiquitous sensing, flexible sensors are developed to overcome the limitations of conventional rigid counterparts. Despite rapid advancement in bench-side research over the last decade, the market adoption of flexible sensors remains limited. To ease and to expedite their deployment, here, we identify bottlenecks hindering the maturation of flexible sensors and propose promising solutions. We first analyze challenges in achieving satisfactory sensing performance for real-world applications and then summarize issues in compatible sensor-biology interfaces, followed by brief discussions on powering and connecting sensor networks. Issues en route to commercialization and for sustainable growth of the sector are also analyzed, highlighting environmental concerns and emphasizing nontechnical issues such as business, regulatory, and ethical considerations. Additionally, we look at future intelligent flexible sensors. In proposing a comprehensive roadmap, we hope to steer research efforts towards common goals and to guide coordinated development strategies from disparate communities. Through such collaborative efforts, scientific breakthroughs can be made sooner and capitalized for the betterment of humanity.

“…Innovative current collector materials are required for the development of practical clean energy (renewable and hydrogen energies) power conversion systems as well as the advancement in system-powered wearable devices and electric vehicles. − New current collectors should meet the following requirements: (i) large specific surface area to allow high mass loading of active materials and low interfacial contact resistance, (ii) low density to enhance the weight fractions of the active materials relative to the total mass of electrodes, (iii) efficient heat dissipation during charge and discharge cycling, (iv) a wide range of potential windows for maintaining electrochemical stability, and (v) good mechanical robustness for the mass production of commercial cells, which includes coating, rolling, and winding processes . A number of alternatives based on two- or three-dimensional metal current collectors in the forms of meshes, foams, , and ultrathin films have been suggested.…”

The increasing demands for conversion systems for clean energy, wearable devices powered by energy storage systems, and electric vehicles have greatly promoted the development of innovative current collectors to replace conventional metal-based foils, including those in multidimensional forms. In this study, carbon nanotubes (CNTs) with desirable features and ease of processing are used in the preparation of floating catalyst–chemical vapor deposition-derived CNT sheets for potential use as all-around current collectors in two representative energy storage devices: batteries and electrochemical capacitors. Due to their short and multidirectional electron pathways and multimodal porous structures, CNT-based current collectors enhance ion transport kinetics and provide many ion adsorption and desorption sites, which are crucial for improving the performance of batteries and electrochemical capacitors, respectively. By assembling activated carbon–CNT cathodes and prelithiated graphite–CNT anodes, high-performance lithium-ion hybrid capacitors (LIHCs) are successfully demonstrated. Briefly, CNT-based LIHCs exhibit 170% larger volumetric capacities, 24% faster rate capabilities, and 21% enhanced cycling stabilities relative to LIHCs based on conventional metallic current collectors. Therefore, CNT-based current collectors are the most promising candidates for replacing currently used metallic materials and provide a valuable opportunity to possibly redefine the roles of current collectors.
