Our approach provides a new framework for visualizing accurate stimulus distribution with potential applications in skin prosthesis, robotics, and advanced human-machine interfaces.Įlectronic skin (e-skin) seamlessly interfaces living organisms with computers, realizing novel applications such as health monitoring 1, 2, medical implants 3, 4, and user interfaces for augmented reality (AR) 5, 6. The device comprises a transparent pressure-sensing film with a solution-processable cellulose/nanowire nanohybrid network featuring ultrahigh sensor sensitivity (>5000 kPa −1) and a fast response time (1000 dpi) pressure imaging without the need for pixel structures. Here, we report an ultraflexible and transparent electroluminescent skin that autonomously displays super-resolution images of pressure distribution in real time. However, existing methods show poor spatial and temporal fidelity due to their limited pixel density, low sensitivity, or low conformability.

With the stretchable and flame-retardant translucent barriers, the MMT-hydrogel skinned soft robots demonstrate stable compression/relaxation cycles (25 cycles) within flames (4 min 10 s) while protecting the electronic components inside in fire scene.

min −1) for translating inside fire applications.

We deploy shape memory alloy (SMA) actuated inchworm-, starfish-, and snail-like locomotion (average velocity ∼12 mm MMT-hydrogel synthetic skin medium is then applied to everyday household items and electronics, offering appealing protections in fire scenes (≤10% capacitance loss after 3 min and ≤14% diode light-intensity loss after 1 min in fire). Fatigue test results in the MMT-hydrogel polymer matrix to portray a change in post-fire energy consumption of ∼21% (between the first cycle and the 200th cycle), further indicating robustness. Here, we establish fire-resistant robotic mechanisms with montmorillonite (MMT)-biocompatible hydrogel skin, offering effective flame retardancy (∼78☌ surface temperature after 3 min in fire) and high post-fire stretchability (∼360% uniaxial tensile strain). In fire scenes, a flame-retardant soft robot shall protect integrated electronic components safely and work for navigation and surveillance effectively.

These multi-segment motion generation systems call for conformable yet resilient skin for dexterous work, including firefighting, packaging inflammable substances, encapsulating energy storage devices, and preventing from burning. Flame-retardant coatings are crucial for intelligent systems operating in high-temperature (300–800☌) scenarios, which typically involve multi-joint discrete or continuous kinematic systems.
