Time‐Encoded Geometric Encryption Enabled by Shape‐Memory Hydrogel with Photoisomerization‐Gated Autonomous Recovery

Baoyi Wu, Yijun Su, Q I Ke, Muqing Si et autres

Leveraging spatiotemporal shape-changing of information-bearing morphologies, materials with predetermined autonomous-shape-morphing potentially offer a unique form of time-encoded geometric communication in contrast to existing optical encryption methods. However, fundamental mechanisms and control strategies underlying the spatiotemporal programmability remain insufficiently explored, thus the information …

4D printing of trigger-free shape-memory hydrogels towards self-adaptive substrates for bioelectronics

Chujun Ni, Chunlei Zhang, Zhenwei Qin, Ke Qiao et autres

Shape-changing smart substrates are revolutionizing implantable bioelectronics by offering minimal invasiveness and self-adaptive geometric conformity. However, precise manipulation of shapeshifting, which is critical for the successful implantation, are hindered by triggering accessibility and cumbersome customization. Here we introduce a digital 4D printing …
