Abstract

Soft transportation devices with high flexibility, good stability, and quick controllability have attracted increasing attention. However, a smart soft transportation device with tactile perception and a non-contact actuating mode remains a challenge. This work reports a magnetic soft pipeline (MSP) composed of sensor film, a magnetorheological elastomer (MRE) cavity pipeline, and heater film, which can not only respond well to tactile compression stimuli but also be transported by magnetic actuation. Notably, the sensor film was integrated on the upper surface of an MRE pipeline, and the relative resistance change (∆R/R0) of the MSP was maintained at 55.8% under 2.2 mm compression displacement during 4000 loading cycles. Moreover, the heater film was integrated on the lower surface of the MRE pipeline, which endows the MSP with an electrothermal heating characteristic. The temperature of the MSP can be increased from 26.7 °C to 38.1 °C within 1 min under 0.6 V. Furthermore, the MSP was attracted and deformed under the magnetic field, and the ∆R/R0 of the MSP reached 69.1% under application of a 165 mT magnetic field density. Benefiting from the excellent perception and magnetic deformation performances, the magnetic actuate transportation of the MSP with self-sensing was successfully achieved. This multi-functional soft pipeline integrated with in situ self-sensing, electrothermal heating, and non-contact magnetic actuating transportation performance possess high potential in smart flexible electronic devices.

具有自我感知功能的磁动传输管道

具有高柔性、良好稳定性和快速可控性的软运输设备越来越受到人们的关注。然而，具有触觉感知和非接触执行模式的智能软运输装置仍然是一项挑战。这项研究报告了一种由传感器薄膜、磁流变弹性体（MRE）空腔管道和加热器薄膜组成的磁性软管道（MSP），它不仅能对触觉压缩刺激做出良好反应，还能通过磁驱动进行传输。值得注意的是，传感器薄膜集成在 MRE 管道的上表面，在 4000 次加载循环中，在 2.2 毫米的压缩位移下，MSP 的相对电阻变化（∆R/R0）保持在 55.8%。此外，加热器薄膜集成在 MRE 管道的下表面，使 MSP 具有电热特性。在 0.6 V 电压下，MSP 的温度可在 1 分钟内从 26.7 °C 升至 38.1 °C。此外，MSP 还能在磁场中被吸引和变形，在 165 mT 的磁场密度下，MSP 的 ∆R/R0 达到 69.1%。得益于出色的感知和磁变形性能，成功实现了 MSP 的自感应磁动传输。这种集原位自感应、电热加热和非接触磁驱动传输性能于一体的多功能软管道在智能柔性电子设备中具有很大的应用潜力。
