“…Developing a powerful micro-engine capable of continuous operation is vital for next-generation micro-robotics 1,2) and a micro-air vehicle (MAV). [3][4][5][6][7][8][9][10][11] In particular, MAVs have attracted much attention [3][4][5][6][7][8][9][10][11] because of the ability to slip through bushes and excellent mobility to escape from enemies, which were previously only possible in creatures such as insects and birds. For example, Bachmann et al 7) reported a small (30.5 cm wingspan), lightweight (∼100 g) carbon fiber vehicle using a small motor that can fly, while Ma et al 12) developed a biologically inspired insect-scale robot and demonstrated tethered but unconstrained stable hovering.…”

Developing powerful micro-engine capable of continuous operation is vital for a next-generation micro air vehicle (MAV). Here, we propose a centimeter-scale MAV using explosive evaporation due to underwater electrical discharge. Specifically, by fabricating the MAV (which is tethered to a pendulum and consists of an L-shaped tube and a pair of discharge electrodes), we demonstrate that the MAV can continue to move in the air with the maximum velocity of $\sim$0.4 m/s. Moreover, through the additional experiment, we found that our device can be used in an untethered state by using a pair of electrodes as an antenna with a pair of external electrodes. Our findings should contribute to next-generation MAV in the future.

“…The key structure of aircraft that enables the deformation is the deformable wing skin structure, which can continuously smooth the deformation [4][5][6]. The emergence of smart materials provides an important material foundation for the development of deformable wing skin structures [7][8][9]. Among them, shape memory polymer composites (SMPCs) are noteworthy and are composed of shape memory polymer (SMP) as the matrix and various fibers (such as carbon fiber, glass fiber, and aramid fiber) as the reinforcement [10][11][12].…”

With the continuous increase in human demand to improve aircraft performance, intelligent aircraft technologies have become a popular research field in recent years. Among them, the deformable skin structure has become one of the key technologies to achieve excellent and reliable performance. However, during the service, deformable skin structures may encounter problems such as surface impact and adhesion of droplets in rainy weather or surface icing in low-temperature environments, which can seriously affect the flight safety of the aircraft. One way to overcome these issues is to use superhydrophobic shape memory materials in the structure. In this regard, first, shape memory composites were prepared with shape memory epoxy resin as the matrix and carbon fiber orthogonal woven fabric as the reinforcement material. Superhydrophobic shape memory composites (SSMCs) were then obtained by casting the kirigami composite with superhydrophobic carbon nanotube–polydimethylsiloxane (CNT@PDMS) mixture, and the surface was processed by laser micromachining. Shape memory performance and surface wetting performance were determined by material testing methods. The results showed that the shape memory recovery rate can reach 85.11%, the surface is superhydrophobic, the average water contact angle is 156.9 ± 4.4°, and the average rolling angle is 3 ± 0.5°. The three-point bending test of the specimens with different kirigami cell configurations showed that the shape memory composite based on the rectangular structure has the best deformability with an aspect ratio of 0.4. From the droplet impact test, it was found that the impact speed of water droplets and the curvature of the surface can greatly affect the dynamic performance of water. This work is expected to be of significant research value and importance for developing functional deformable skin materials.
