Mechanosensing, the transduction of extracellular mechanical stimuli into intracellular biochemical signals, is a fundamental property living cells. However, endowing synthetic materials with mechanosensing capabilities comparable to biological levels challenging. Here, we developed ultrasensitive and robust mechanoluminescent composites using hydrogels embedded dinoflagellates, unicellular microalgae near-instantaneous bioluminescent response stress. Not only did dinoflagellates retain their intrinsic mechanoluminescence, but hydrophobic coatings, had lifetime ~5 months under harsh conditions minimal maintenance. We 3D-printed large-scale structures high spatial resolution, also enhanced properties double-network hydrogels. propose counterpart mathematical model that captured experimental observations predict mechanoluminescence based on deformation applied demonstrated use for biomimetic soft actuators emitted colored light upon magnetic actuation. These have substantial potential in biohybrid sensors robotics.

Abstract Centrosymmetric-oxide/polydimethylsiloxane elastomers emit ultra-strong non-pre-irradiation mechanoluminescence under stress and are considered one of the most ideal materials. However, previous centrosymmetric-oxide/polydimethylsiloxane show severe degradation stretching, which limits their use in applications. Here we an elastomer based on centrosymmetric fluoride CaF 2 :Tb 3+ polydimethylsiloxane, with that can self-recover after each stretching. Experimentation indicates self-recoverable /polydimethylsiloxane occurs essentially due to contact electrification arising from contact-separation interactions between phosphors polydimethylsiloxane.
