ve soft pressure sensors have attracted tremendous attention in recent years due to their great promise in robotics, healthcare, smart wearables, etc. Although high sensitivities can be realized by existing sensing mechanisms, they usually cause large random errors owing to inhomogeneous sensing layers, thus considerably reducing the sensing precision for practical applications. Herein, a pure-polymer and field emission bilayer structure (PFEBS)-based transduction mechanism is presented to successfully design an ultrasensitive and ultraprecise soft pressure sensor for the first time. This unique structure enables numerous tunneling electrons generated by field emission to be transmitted through the homogeneous sensing layer, which undergoes uniform deformation under subtle pressures, simultaneously achieving a sensing precision with variation <1.62% and a sensitivity of 372.2 kPa^-1 . This study offers a new design strategy to develop next-generation high-performance flexible pressure sensors for soft systems.23:T443,Abstract Highly sensitive electronic skin (e‐skin) sensors with considerable operating range offer great possibilities for health care, human–‐machine interfaces, and intelligent robotics. Although subtle microstructures have been used in recent years to improve the sensitivity and sensing range of e‐skin sensors, the trade‐off between these features remains a big challenge to overcome. Here, an asymmetric interlocked gradient elastic modulus (AIGM) structure is designed for the first time to provide sufficient deformation space to the traditional interlocked structure while ensuring high sensitivity, and the gradient elastic modulus further extends the sensing range of the AIGM structure‐based sensors, which exhibit a maximum sensitivity of as high as 9.89 kPa −1 with an ultrawide working range that extends to above 530 kPa at the same time. As a demo, this sensor is integrated into an intelligent adjustable mouse platform for physiological signal monitoring, pressure feedback, and modulus adjustment, providing a viable alternative for hand disease prevention.24:T534,While electrocatalytic reduction of nitrate to ammonia presents a sustainable solution for addressing both the environmental and energy issues within the nitrogen cycle, it remains a great challenge to achieve high selectivity and activity due to undesired side reactions and sluggish reaction kinetics. Here, we fabricate a series of metal-N-C catalysts that feature hierarchically ordered porous structure and high-density atomically dispersed metals (HD M₁/PNC). Specifically, the as-prepared HD Fe₁/PNC catalyst achieves an ammonia production rate of 21.55 mol g_cat^-1 h^-1 that is at least 1 order of magnitude enhancement compared with that of the reported metal-N-C catalysts, while maintaining a 92.5% Faradaic efficiency when run at 500 mA cm^-2 for 300 h. In addition to abundant active sites, such high performance benefits from the fact that the high-density Fe can more significantly activate the adjacent N/C sites through charge redistribution for improved water adsorption/dissociation, providing sufficient active hydrogen to Fe sites for nitrate ammoniation, compared with the low-density counterpart. This finding deepens the understanding of high-density metal-N-C materials at the atomic scale and may further be used for designing other catalysts.
