“…A few emerging devices and components have achieved dual functions by integrating two devices: temperature and humidity sensors, nanogenerators and supercapacitors for selfpowering, triboelectric nanogenerators for self-powered sensing, and humidity sensors and actuators. Indeed, the integration of supercapacitors [393] with logic devices leads to self-powering and self-charging [394]. More innovations may turn in for enriching the device design and fabrication.…”

Human beings perceive the world through the senses of sight, hearing, smell, taste, touch, space, and balance. The first five senses are prerequisites for people to live. The sensing organs upload information to the nervous systems, including the brain, for interpreting the surrounding environment. Then, the brain sends commands to muscles reflexively to react to stimuli, including light, gas, chemicals, sound, and pressure. MXene, as an emerging two-dimensional material, has been intensively adopted in the applications of various sensors and actuators. In this review, we update the sensors to mimic five primary senses and actuators for stimulating muscles, which employ MXene-based film, membrane, and composite with other functional materials. First, a brief introduction is delivered for the structure, properties, and synthesis methods of MXenes. Then, we feed the readers the recent reports on the MXene-derived image sensors as artificial retinas, gas sensors, chemical biosensors, acoustic devices, and tactile sensors for electronic skin. Besides, the actuators of MXene-based composite are introduced. Eventually, future opportunities are given to MXene research based on the requirements of artificial intelligence and humanoid robot, which may induce prospects in accompanying healthcare and biomedical engineering applications.

“…Due to the increasingly severe problem of environmental pollution resulting from the overuse of fossil fuels in the past few decades, there is an urgent need for the development of sustainable and clean energy systems that can minimize the emission of carbon dioxide. [1][2][3][4] Among many alternative clean energy sources, hydrogen is considered to be an ideal energy carrier precisely thanks to its high energy density, good thermal conductivity, and environmental friendliness, which has attracted more attention both academically and industrially in recent years. 5,6 However, the problems of green production and safe storage of hydrogen hinder its widespread application nowadays.…”

“…[25][26][27] However, the thermal decomposition of AB has some disadvantages, such as a long induction period of hydrogen release, foaming of solid products, and detrimental by-products. Therefore, researchers focused on the hydrolysis reaction of AB due to its facile processing, which can be expressed as eqn (1):…”

“…Sustainable energy systems always include various renewable energy sources, such as wind, solar, hydro, etc., but those renewable energy sources are intermittent within hours, days, or even seasons, which are nonreliable and cannot be directly connected to the current electric grid [ 1 , 2 , 3 , 4 ]. Therefore, an ideal energy carrier that can mitigate the differences between energy supplies and demands is critical for developing sustainable energy systems [ 5 , 6 , 7 , 8 , 9 ]. Hydrogen accounts for about only 2% of the world energy consumption at present, while it has been proposed as one of the most promising energy carriers in the next few decades by most of the governments in the world to achieve carbon emission reductions [ 10 , 11 , 12 , 13 ], due to its high energy density, low weight, environmentally friendly, and abundant reserves in water [ 14 , 15 , 16 , 17 , 18 ].…”

The electrode, as one of the most critical components in a proton exchange membrane water electrolysis (PEMWE) cell for hydrogen production, has a significant impact on cell performance. Electrodes that are fabricated via various techniques may exhibit different morphologies or properties, which might change the kinetics and resistances of the PEMWE. In this study, we have successfully fabricated several electrodes by different techniques, and the effects of electrode coating methods (ultrasonic spray, blade coating, and rod coating), hot press, and decal transfer processes are comprehensively investigated. The performance differences between various electrodes are due to kinetic or high frequency resistance changes, while the influences are not significant, with the biggest deviation of about 26 mV at 2.0 A cm−2. In addition, the effects of catalyst ink compositions, including ionomer to catalyst ratio (0.1 to 0.3), water to alcohol ratio (1:1 to 3:1), and catalyst weight percentage (10% to 30%), are also studied, and the electrodes’ performance variations are less than 10 mV at 2.0 A cm−2. The results show that the PEMWE electrode has superior compatibility and redundancy, which demonstrates the high flexibility of the electrode and its applicability for large-scale manufacturing.
