Tactile electronic skins (e-skins) are flexible devices that aim to replicate tactile sensing capabilities of the human skin, while possessing skin-like geometric features and materials properties. Since skin is composed complex 3D constructions, where various types mechanoreceptors distributed in a spatial layout, an important trend e-skin development involves introduction device architectures can certain structural skins. The resulting architected e-skins have demonstrated advantages detection shear forces decoupled perception multiple mechanical stimuli, which pivotal importance many application scenarios. In this perspective, we summarize main biological prototypes existing e-skins, focus on key related capabilities. Then highlight enhanced terms super-resolution predictions diverse physical properties surface object, allow for broad spectrum practical applications, such as object recognition, human-machine interactions, dexterous manipulation, health monitoring. Finally, discuss scientific challenges opportunities future developments e-skins.

Flexible piezoresistive pressure sensors have great potential in wearable electronics due to their simple structure, low cost, and ease of fabrication. Porous polymer materials, with highly deformable internal pores, effectively expand the sensing range. However, a single-sized pore structure struggles achieve both high sensitivity broad range simultaneously. In this study, PDMS-based flexible sensor bilayer porous (BLPS) was successfully fabricated using clamping compression sacrificial template method spherical sucrose cores. The resulting exhibits uniform sizes, thereby improving performance consistency. Furthermore, since different sizes thicknesses correspond varying Young’s moduli, study achieves tunable across wide by adjusting thickness ratio (maximum 0.063 kPa−1 0–23.6 kPa range, response 0–654 kPa). also demonstrates fast time (128 ms) excellent fatigue stability (>10,000 cycles). Additionally, holds application for facial expression monitoring, joint motion detection, distribution matrices, Morse code communication.

Abstract Bimode temperature‐pressure sensors hold significant promise in personal health monitoring, wearables and robotic signal detection. Traditional bimode typically combine two independent sensors, leading to fabrication complexity. This study develops a sensor by using facile electrodeposition method create sandwiched BiSbTe/Carbon Paper/BiSbTe thin films stacking them vertical structure. It demonstrates high sensitivity for temperature sensing, capable of detecting difference as low 1 K, rapid response time 0.92 s due Utilizing its thermoelectric mechanism, the achieves self‐powered sensing finger touch respiration states. Furthermore, island‐like contact surface ensures with an extremely fast 0.17 s, rapidly changing resistance under pressure, allowing it detect various human behaviors, including body movements micro‐expressions. Beyond capabilities, film excels flexibility, electromagnetic interference shielding, stability, presenting potential integration into electronic skin systems wearables, artificial intelligence, other applications.
