Stretchable Silicon–Liquid Metal Imager
Built on single-crystalline silicon pixels interconnected by finely patterned liquid metal on ultrathin elastomeric substrates, this high-fill-factor stretchable imaging platform enables a human-eye-inspired robotic vision system and a skin-mountable, lens-free imager for multiscale visual acquisition and depth sensing.



Sub-1-Volt Full-Colour Reflective Monopixels
By integrating a conductive polymer with an electrically reconfigurable Gires–Tournois resonator, we have developed a full-colour reflective monopixel that achieves vivid colour modulation at sub-1-volt operation, with ultralow power, ultrahigh pixel density, and memory-in-pixel functionality.



Foliage-Inspired Hydrogel Thermostat
Inspired by the photoprotective foliage of Populus alba, we have developed a hydrogel-based latent–radiative thermostat that balances latent and radiative heat fluxes — switching solar reflectance while maintaining high mid-IR emissivity — for power-free, adaptive thermal management.



Synapse-Inspired In-Sensor Image Processing
A ferroelectric-gated phototransistor, modeled on the tripartite synapse, memorizes visual information as photoconductance through electrical and optical non-volatility — enabling active in-sensor processing that recalibrates distorted, unstructured light into a learned range without complex post-processing.
