“…The displacement output of a sufficient application can then be produced through the displacement amplifier. Sun et al [ 145 ] designed and studied an integrated actuator that can solve the problem of precise positioning and vibration control of spacecraft optical components at the same time, and the experimental results showed that this integrated actuator had excellent vibration suppression ability and high-precision output performance in low-frequency bands. Recent studies have shown the feasibility of GMM materials as self-sensing actuators, and it is believed that GMM actuators have the potential to realize the functions of self-sensing and precise positioning at the same time, which can further simplify the structure of the system [ 146 , 147 ].…”

The rapid development of the aviation industry has put forward higher and higher requirements for material properties, and the research on smart material structure has also received widespread attention. Smart materials (e.g., piezoelectric materials, shape memory materials, and giant magnetostrictive materials) have unique physical properties and excellent integration properties, and they perform well as sensors or actuators in the aviation industry, providing a solid material foundation for various intelligent applications in the aviation industry. As a popular smart material, piezoelectric materials have a large number of application research in structural health monitoring, energy harvest, vibration and noise control, damage control, and other fields. As a unique material with deformation ability, shape memory materials have their own outstanding performance in the field of shape control, low-shock release, vibration control, and impact absorption. At the same time, as a material to assist other structures, it also has important applications in the fields of sealing connection and structural self-healing. Giant magnetostrictive material is a representative advanced material, which has unique application advantages in guided wave monitoring, vibration control, energy harvest, and other directions. In addition, giant magnetostrictive materials themselves have high-resolution output, and there are many studies in the direction of high-precision actuators. Some smart materials are summarized and discussed in the above application directions, aiming at providing a reference for the initial development of follow-up related research.

“…Moreover the Young's modulus of GMM is not a constant under changing external conditions, also known as the ∆E effect [3]. Due to its higher energy density and intrinsic robustness, the giant magnetostrictive actuator (GMA) is presently used as a core component in industrial and aerospace fields [4][5][6]. Recent research has proven that GMM, without additional sensors, can be exploited to obtain its output displacement [7], velocity [8] and force [9,10].…”

Giant magnetostrictive material (GMM) has the smart potential to be integrated as a self-sensing actuator. This paper presents a novel self-sensing giant magnetostrictive actuator (SSGMA), by sensing the on-line stiffness of the actuator upon the ΔE effect. A self-sensing signal is generated by superimposing a set of high-frequency small sensing excitation magnetic fields on low-frequency static or quasi-static driving magnetic fields. The fully coupled magneto-elastic-thermal nonlinear constitutive model of GMM is derived, and then the self-sensing response model of the SSGMA based on the nonlinear equivalent piezomagnetic equation is proposed. On the theoretical basis, the influences of magnetic field, prestress and temperature on the ΔE effect, the equivalent piezomagnetic equation parameters and the SSGMA sensing signal are investigated in detail, respectively. Moreover, a prototype of the SSGMA is fabricated and tested for self-sensing performance. The experimental results demonstrate the effectiveness of the theoretical analysis, and further show that the proposed SSGMA achieves self-sensing output displacement within a stroke of nearly 50 μm, with a sensitivity of 2.49 mV/μm. The self-sensing displacement resolution of the SSGMA by far may reach 63.4 nm after experimental determination. This novel self-sensing actuator with micron-level self-sensing drive capability can be integrated into an external sensorless execution system in the future.
