An emulsion hydrogel motor (E-H motor), constituted by low-boiling-point oil fuel and a hydrogel matrix, is prepared through a simple yet versatile oil-in-water (O/W) emulsion template method. The E-H motor can be efficiently propelled by the bubbles generated under a thermal stimulus. As thermally induced explosion occurs inside the E-H motor (diameter ∼4.0 mm and length ∼6.0 mm), the gas bubbles resulting from thermotropic phase transition are violently ejected from one side, leading to a fast speed of 14.78 ± 4.82 mm s–1 in a 60 °C aqueous solution. Additionally, multiple water-insoluble organic solvents can serve as the fuel for self-propulsion, which demonstrates the favorable universality of the E-H motor. The magnetic navigation and near-infrared propulsion can be realized through incorporating hydrophilic iron oxide (Fe3O4) nanoparticles and graphene oxide (GO) into the aqueous phase. Moreover, the synchronous integration of GO and enrofloxacin bactericide can enable intelligent targeted cargo transportation and delivery. The attractive self-propulsion performance, precise locomotion control, and formidable integration ability of the emulsion hydrogel-based miniaturized soft motor hold great promise for numerous practical applications.

热刺激驱动乳液水凝胶软马达
通过简单而通用的水包油（O / W）乳液模板方法，制备了由低沸点燃油和水凝胶基质组成的乳液水凝胶电机（EH电机）。在热刺激下产生的气泡可以有效地推动EH电机。当EH电机内部发生热爆炸（直径〜4.0 mm，长度〜6.0 mm）时，由热致相变产生的气泡从一侧猛烈喷出，导致14.78±4.82 mm s –1的快速速度在60°C的水溶液中。此外，多种水不溶性有机溶剂可以用作自推进燃料，这证明了EH电机具有良好的通用性。通过将亲水性氧化铁（Fe 3 O 4）纳米粒子和氧化石墨烯（GO）掺入水相中，可以实现磁导航和近红外推进。此外，GO和恩诺沙星杀菌剂的同步整合可以实现智能的目标货物运输和交付。基于乳液水凝胶的微型软电机具有吸引力的自推进性能，精确的运动控制和强大的集成能力为许多实际应用提供了广阔的前景。
