Flexible pressure sensors have attracted significant attention owing to their broad applicability in wearable electronics and human-machine interfaces. However, it is still challenging simultaneously achieve a sensing range high linearity. Here, we present reversed lattice structure (RLS) piezoresistive sensor obtained through layer-level engineered additive infill via conventional fused deposition modeling three-dimensional (3D) printing. The optimized RLS attained (0.03-1630 kPa) with linearity (coefficient of determination, R2 = 0.998) sensitivity (1.26 kPa-1) due the structurally enhanced compressibility spontaneous transition dominant mechanism sensor. It also exhibited great mechanical/electrical durability rapid response/recovery time (170/70 ms). This remarkable performance enables detection various human motions over spectrum, from pulse walking. Finally, electronic glove was developed analyze distribution situations, thereby demonstrating its multipurpose electronics.

Abstract Electronic skins (E‐Skins) are crucial for future robotics and wearable devices to interact with perceive the real world. Prior research faces challenges in achieving comprehensive tactile perception versatile functionality while keeping system simplicity lack of multimodal sensing capability a single sensor. Two kinds sensors, transient voltage artificial neuron (TVAN) sustained potential (SPAN), featuring self‐generated zero‐biased signals developed realize synergistic information (vibration, material, texture, pressure, temperature) device instead complex sensor arrays. Simultaneously, machine learning feature fusion is applied fully decode their output compensate inevitable instability force, speed, etc, applications. Integrating TVAN SPAN, formed E‐Skin achieves holistic touch awareness only unit. It can thoroughly an object through simple without strictly controlled testing conditions, discern surface roughness from 0.8 1600 µm, hardness 6HA 85HD, correctly distinguish 16 objects temperature variance 0 80 °C.

Abstract Self‐healing ionic conductive hydrogels have shown significant potential in applications like wearable electronics, soft robotics, and prosthetics because of their high strain sensitivity mechanical electrical recovery after damage. Despite the enormous interest these materials, conventional fabrication techniques hamper use advanced devices since only limited geometries can be obtained, preventing proper conformability to complexity human or robotic bodies. Here, a photocurable hydrogel with excellent deformations based on semi‐interpenetrating polymeric network is reported, which holds remarkable properties (ultimate tensile 550%) spontaneous self‐healing capabilities, complete its damages. Furthermore, developed material processed by digital light processing 3D printing technology fabricate complex‐shaped sensors, increasing stress respect simple sensor geometries, reaching an exceptional pressure detection limit below 1 Pa. Additionally, used as electrolyte laser‐induced graphene‐based supercapacitor, then incorporated into 3D‐printed create self‐powered, fully integrated device. These findings demonstrate that using printing, it possible produce multifunctional, self‐powered appropriately shaped depending various applications, without bulky batteries.
