Here, model blister-like soft thermo-pneumatic artificial muscles with the embedded nanofibers impregnated with ethanol are developed. The muscles are essentially blister-like thermo-pneumatic soft actuators (BTSAs), which deflect in response to heat supplied to their bottom. The resulting deflections are on the scale of 1 cm, and the BTSAs are operational for several cycles. They are able to raise the artificial rigid scales, spines or fur/thin fibers attached to them emulating animals such as pangolin, hedgehog and porcupine. They are also capable of removing the stickiest adhesive tapes attached to them, and thus hold great promise for biomedical applications where artificially grown skin patches should be removed from an underlying substrate without being damaged. The theory of the BTSA proposed in this work is in reasonable agreement with the acquired experimental data.
在这里，开发了具有嵌入式纳米纤维的模型水疱状软热气动人工肌肉，其中浸渍有乙醇。肌肉本质上是水疱状热气动软致动器（BTSA），它们响应底部供应的热量而弯曲。产生的挠度在 1 厘米的范围内，并且 BTSA 可以进行几个周期的操作。它们能够提升附着在其上的人造刚性鳞片、刺或毛发/细纤维，模仿穿山甲、刺猬和豪猪等动物。它们还能够去除附着在其上的最粘性的胶带，因此在生物医学应用中具有很大的潜力，例如应该将人工生长的皮肤贴片从底层基质上取下而不会损坏。本工作中提出的 BTSA 理论与获得的实验数据基本一致。
