Origami device fabrication has huge potential in the fields of health, agriculture, and space technology. However, portability of the presently used fabrication devices is a concern and on-site production of three-dimensional (3D) devices remains a challenge. To address this, researchers have developed a portable, multimaterial printer using electrowetting on dielectric technology. This device allows rapid fabrication of 3D devices, eliminating the challenges of the existing technologies and improving the applicability of paper-based devices.

The civilian GPS signals are vulnerable to spoofing attacks in UAV system. A new on-board algorithm named MSSTP-OAD enables low-cost drones to detect counterfeit GPS positions in real time using only their existing GPS receiver and inertial unit—no extra radios, antennas or ground stations required. Compared to existing LSTM-based algorithms, the proposed method can achieve 98.4 % accuracy, 24 % faster detection and 26 % shorter recovery distance.

High altitude long endurance aircraft, benefitting from excellent aerodynamic performance and dwell time, could suffer aerodynamic and structural nonlinearities during severe environments. These coupled nonlinearities can result in unfavorable aeroelastic responses, posing a potential threat to structural integrity and flight safety. Most studies focused only on aeroelastic systems with isolated structural or aerodynamic nonlinearity. It is necessary to fill this research gap since coupled nonlinearities can cause significantly different aeroelastic signatures that cannot be captured in an isolated nonlinear case.

Unmanned aerial vehicles (UAVs), characterized by their low cost and operational flexibility, can be utilized to realize the comprehensive spatial coverage for the sixth-generation mobile networks. However, the private data in UAV networks is easy to be exposed due to the line-of-sight links and openness of wireless transmission. Covert communication as an emerging technique has shown its superiority in hiding the transmission behavior to further enhance the security of UAV networks. Therefore, we present a survey on the recent advanced research about covert UAV communications.

UAV shipboard landing has gained extensive attention, due to its potential to enhance operational efficiency in maritime applications, including surveillance, inspection, refueling, and sea rescue missions. However, the oscillatory ship motion caused by the sea wave interactions and wind gusts, especially in rough sea states, may lead to UAV trajectory deviations or even collisions, significantly escalating the challenge of shipboard landing. Consequently, the development of safe and reliable UAV shipboard landing techniques is of great importance and remains a critical research priority.
