“…With the rapid development of bionics [ 5 , 6 ], fluid mechanics, computers [ 7 ], and intelligent control technology, as well as the emergence of new materials, scholars have gradually turned to the research of aquatic animal motion mechanisms to seek new underwater propulsion methods [ 8 , 9 , 10 , 11 , 12 ]. After hundreds of millions of years of evolution, underwater organisms have evolved various capabilities adapted to water movement [ 13 , 14 , 15 ].…”

The propulsion system is the core component of unmanned underwater vehicles. The flapping propulsion method of marine animals’ flippers, which allows for flexibility, low noise, and high energy utilization at low speeds, can provide a new perspective for the development of new propulsion technology. In this study, a new experimental flapping propulsion apparatus that can be installed in both directions has been constructed. The guide rail slider mechanism can achieve the retention of force in the direction of movement, thereby decoupling thrust, lift, and torque. Subsequently, the motion parameters of frequency–amplitude related to the thrust and lift of a bionic flapping-foil are scrutinized. A response surface connecting propulsion efficiency and these motion parameters is formulated. The highest efficiency of the flapping-foil propulsion is achieved at a frequency of 2 Hz and an amplitude of 40°. Furthermore, the impact of the installation mode and the aspect ratio of the flapping-foil is examined. The reverse installation of the swing yields a higher thrust than the forward swing. As the chord length remains constant and the span length increases, the propulsive efficiency gradually improves. When the chord length is extended to a certain degree, the propulsion efficiency exhibits a parabolic pattern, increasing initially and then diminishing. This investigation offers a novel perspective for the bionic design within the domain of underwater propulsion. This research provides valuable theoretical guidance for bionic design in the underwater propulsion field.

In response to the limitations of the single‐chamber water jet thruster used in underwater vehicles mimicked by natural cephalopods, a novel approach involving a double‐chamber water jet thruster has been proposed. This thruster utilizes electromagnetic force to manipulate the diaphragm, thereby altering the volume of the upper and lower chambers to achieve water jet propulsion. Experimental investigations were conducted to determine the tensile length‐force characteristics of the diaphragm made of Agileus30. Subsequently, key parameters of essential propulsion components, such as solenoid coils, electromagnets, and currents, were established based on the tensile length‐force curve, and the propulsion capabilities of the system were evaluated through theoretical analysis. Theoretical assessments indicate that the system does not produce reverse thrust regardless of whether the coil moves up or down. Further experimental results demonstrate that the maximum peak propulsion force generated by the dual‐chamber water jet thruster within a 3‐s cycle is 0.253 N.

The purpose of this paper is to develop a self-detecting diaphragm integrated with a flexible sensor, which is utilized in an underwater thruster. Resistive strain sensors are easy to manufacture and integrate due to their advantages in reliable stretchability and ductility. Inspired by the structure of neurons, we fabricated resistive flexible sensors using silica gel as the matrix with carbon black and carbon nanotubes as additives. All fabricated sensors demonstrated positive resistance characteristics under 60% strain conditions, with the sensor containing a mass ratio of 9 wt % carbon black and carbon nanotubes exhibiting the best resistance−strain linearity. To verify the anti-interference capability of sensors with silica gel substrates of varying hardness values under changing environmental pressure, we tested the pressure sensitivity of the sensors by altering the hardness of the silica gel. The results indicate that silica gel with the highest hardness value provides the best resistance to environmental pressure interference. To detect the motion and deformation of the internal functional components of the thruster, we combined strain detection with the movement operation function of a silica gel diaphragm, resulting in a new integrated diaphragm with sensor detection capabilities. The integrated diaphragm was evaluated by using a tensile testing machine and an LCR tester. The results demonstrate that the mechanical properties of the diaphragm are stable, exhibiting reliable resistance characteristics and a sensitive response during underwater operation. This research can also be applied to the detection of motion amplitudes of other types of soft robots.
