摘要 :
一种仿生昆虫属于仿生机器人领域。本发明通过在二维材料自支撑迈克烯(Ti3C2Tx)薄膜层间梯度填充石蜡(一种高热膨胀率烃链聚合物材料),利用迈克烯(Ti3C2Tx)和石蜡的极大热膨胀差,直接在材料中构造膨胀差异,使其在光、热信号刺激下产生特定幅度弯曲,摆脱了双层结构的限制,大大提高了驱动器工作效率,从而可应用于仿生昆虫中。薄膜可被氧化石墨烯薄膜、碳纳米管薄膜等热导性高,具有分层特性的二维材料替代。石蜡材料可以其他存在固液转化或高热膨胀率材料替代,如PDMS、液晶、水凝胶等。

摘要 :
<正>由于具有多激励、宽谱响应、插入损耗小和响应速度快等优势, VO_2是一种理想的THz波主动调制材料。但是,由于传统半导体基底存在缺乏柔性、热容大、热导率低和不导电等问题,在硬质基底上难以实现高性能VO_2基THz波主动调制器件。为解决上述问题,申请人将VO2生长在顺排CNT薄膜上。顺排CNT薄膜具有沿CNT轴向有序排列的特性。

摘要 :
Photoelectronic performance of organic-inorganic hybrid perovskites has been investigated extensively. Advancement in optoelectronic characterization and application of this group of materials in solar cells, light-emitting diodes, and lasers has been pushed forward rapidly. However, nonlinear optical properties for applications in optical logic devices have not been exploited. Moreover, long-lived excitons and charges limit the response speed of such materials and further construction of ultrafast devices. In this work, we make use of the high third-order optical nonlinearity of (CH3NH3)PbBr3 single crystals and develop a femtosecond optical switch (OS) based on strong two-photon processes through absorbing one pump and one probe photon. The fascinating band structure, with a steep edge at 2.22 eV between the transmission and strong absorption bands, endows single crystals of (CH3NH3)PbBr3 with perfect characteristics for two-photon optical switching in the near infrared. An on-off ratio of the probe pulses of about 90% and a speed faster than 400 fs have been achieved for this OS device. To the best of our knowledge, such high efficiency has not been realized for an ultrafast OS with any other materials and devices. Moreover, this is a first exploration, to our best knowledge, of the third-order optical nonlinearity of organic-inorganic hybrid halide perovskites for application in ultrafast optical logic devices with high reliability and low threshold in the near infrared.

摘要 :
Due to their high flexibility and adaptability, bionic robots have great potential in applications such as healthcare, rescue, and surveillance. The flexible actuator is an essential component of the bionic robot and determines its performance. Even though much progress has been achieved in bionic robot research, there still exists a great challenge in preparing a flexible actuator with a large stroke, high sensitivity, fast response, low triggering power, and long lifetime. This study presents a flexible actuator based on a paraffin wax and Ti3C2Tx MXene (PW-MX) film composite. Such a flexible actuator delivers an excellent actuation performance, including a large curvature change (2.2 x 10(2) m(-1)), high thermal sensitivity (4.6 m(-1)/degrees C), low triggering power of light (76 mW/cm(2)), wavelength selectivity, fast response (0.38 s), and long lifetime (>20000 cycles). Due to the high thermal sensitivity and the strong infrared absorption of the PW-MX film, crawling motion of an inchworm robot based on PW-MX film can be triggered by infrared irradiation from the human finger. To mimic living organisms with bioluminescence, we prepared a PW-MX actuator with green fluorescence by doping PW-MX film with CdSe/ZnS quantum dots. The integration of luminescent function enables the PW-MX actuator to deliver information under light stimulation and to camouflage under a background of green foliage actively. With its merits of ease of fabrication and high actuation performance, the flexible PW-MX actuator is expected to lend itself to more applications in the future.

摘要 :
Mechanical actuators, which convert external stimuli to motion, play a significant role in medical devices, automobiles, aircrafts, and robots. With their associated advantages of large shape change, high force, and high efficiency, phase transitions are among the most important driving forces in actuation. There are many phase-transition materials suitable for actuators, and many of them find applications in the real world. In this Tutorial, we review some typical phase-transition driving materials for actuators, including shape memory alloys, piezoelectric ceramics, vanadium dioxide, liquid crystal elastomers, hydrogels, shape memory polymers, and paraffin wax. The phase-transition mechanisms of the materials are introduced, and the design principles and related applications of the associated actuators are discussed.
