Multi-physics field coupled elastomers for enhanced mechanoluminescence and magneto-optical response

Mechanoluminescence (ML) elastomers have shown great potential in flexible display and sensing devices. However, the dependence on material properties is the current bottleneck. Herein, we introduce an ML enhancement strategy based on multi-physics field coupling, which utilizes the polarization effect between ML materials, magnetic responsive media, and dielectric materials to improve the interfacial triboelectricity of elastomers. Experiments have shown that under the enhancement of a magnetic field, the ML of the sample can reach five times that of the direct mode, and non-contact ML has been achieved. This work not only provides magneto-light responsive ML elastomers but also offers a promising strategy for optimizing the performance of ML materials, providing reference for the design of future ML elastomers.
