Self-powered information encoding devices (IEDs) have drawn considerable interest owing to their capability to process information without batteries. Next-generation IEDs should be reprogrammable, self-healing, and wearable to satisfy the emerging requirements for multifunctional IEDs; however, such devices have not been demonstrated. Herein, an integrated triboelectric nanogenerator-based IED with the aforementioned features was developed based on the designed light-responsive high-permittivity poly(sebacoyl diglyceride--4,4'-azodibenzoyl diglyceride) elastomer (PSeDAE) with a triple-shape-memory effect. The electrical memory feature was achieved through a microscale shape-memory property, enabling spatiotemporal information reprogramming for the IED. Macroscale shape-memory behavior afforded the IED shape-reprogramming ability, yielding wearable and detachable features. The dynamic transesterifications and light-heating groups in the PSeDAE afforded a remotely controlled rearrangement of its cross-linking network, producing the self-healing IED.
自供电信息编码设备（IEDs）因其无需电池即可处理信息的能力而引起了相当大的兴趣。下一代 IEDs 应该是可重编程、自修复和可穿戴的，以满足多功能 IED 的新兴需求；然而，此类设备尚未得到证明。在此，基于设计的光响应高介电常数聚（琥珀酰二甘油酯-4,4'-偶氮二苯甲酰二甘油酯）弹性体（PSeDAE），开发了一种具有上述特征的基于集成摩擦纳米发电机的 IED，该弹性体具有三重形状记忆效应。通过微尺度形状记忆特性实现了电记忆特性，从而实现了 IED 的时空信息重编程。宏观形状记忆行为赋予了 IED 形状重编程能力，产生了可穿戴和可拆卸的特征。PSeDAE 中的动态酯交换和光加热基团提供了其交联网络的远程控制重排，从而产生了自修复 IED。
