“…The review articles on the ERF itself published so far have considered several factors to enhance the field-dependent characteristics [1][2][3][4][5][6][7][8][9][10][11]. For examples, several different particles such as alfa silica, alumina, polyurethane, mannitol, aluminum oleate, boron, carbon, colloidal silica, nylon powder and barium titanate have been mixed with various carrier fluids including silicone oil, transformer oil, dielectric oil, olive oil, caster oil, mineral oil, kerosene, grease and carbon tetrachloride.…”

This paper comprehensively reviews sensors and sensing devices developed or/and proposed so far utilizing two smart materials: electrorheological fluids (ERFs) and magnetorheological materials (MRMs) whose rheological characteristics such as stiffness and damping can be controlled by external stimuli, an electrical voltage for ERFs and a magnetic field for MRMs, respectively. In this review article, the MRMs are classified into magnetorheological fluid (MRF), magnetorheological elastomer (MRE) and magnetorheological plastomer (MRP). To easily understand the history of sensing research using the two smart materials, the order of this review article is organized in a chronological manner of ERF sensors, MRF sensors, MRE sensors and MRP sensors. Among many sensors fabricated from each smart material, one or two sensors or sensing devices are adopted to discuss on the sensing configuration, working principle and specifications such as accuracy and sensitivity. Some sensors adopted in this article include force sensor, tactile device, strain sensor, wearable bending sensor, magnetometer, display device and flux measurement sensor. After briefly describing what have been reviewed in a conclusion, several challenging future works, which should be done for practical applications as sensors or sensing devices, are remarked in terms of new technologies such as artificial intelligence neural network in which several parameters affecting the sensor signals can be precisely tuned or controlled. It is sure that this review article is very helpful to make creative sensors using not only the proposed smart materials but also several different types of smart materials including shape memory alloys and active polymers.

“…4 As its derivatives, graphene oxide (GO) and carbon nanotubes (CNTs) are chemically bonded with sp 2 bonds and have become a hot topic of electrorheological (ER) fluids as a result of their large specific surface area, low density, and abundant surface functional groups, which can significantly enhance the ER responses. 5 ER fluids, with tunable rheological properties 6 (shear viscosity, yield stress, or elastic moduli), are a class of stimuli-responsive "smart" soft materials. 7 When an electric field is applied, the ER fluids undergo a controllable and reversible transition to a solid-like state 8 and can therefore be applied in various fields, such as soft robotics, 9 haptic systems, 10 and even medical devices.…”

The incorporation of nanocarbon-based materials into electrorheological fluids has been shown to be an effective means of improving the electrorheological (ER) response. However, the mechanism of the sp 2 /sp 3hybridized carbon structure and high ER response is still under investigation. Herein, barium titanate@nanocarbon shell (BTO@NCs) composites are proposed and prepared by introducing carbonized polydopamine (C-PDA) into a shell. When the polymerization time of dopamine is tuned, the shell thickness, surface polar functional groups, and sp 2 /sp 3 -hybridized carbon can be effectively controlled. The maximum yield stress of the BTO@NCs-24 h ER fluid reaches 2.5 kPa under an electric field of 4 kV mm −1 , which is attributed to the increased content of sp 3 C−OH and oxygenous functional groups within the shell, resulting in a rapidly achievable polarization. Furthermore, the SiO 2 @NCs and TiO 2 @NCs ER fluids are also prepared with enhanced ER behavior in these phenomena, confirming an approach to high-performance ER fluids based on nanocarbon composites.

“…Under the action of high voltage electric field, the ERF can be converted from liquid material to solid material in milliseconds, and it is continuous, reversible and controllable, with fast response, high damping and low power consumption [2][3][4] . Therefore, ERF can be widely used in industrial fields, such as buffers, clutches, shock absorbers, brakes, electromechanical coupling control, etc [5] .…”

Based on the shock absorber as the application background, a kind of Strontium Titano-Oxalate (STO) electrorheological material was synthesized. According to the mass ratio of STO electrorheological fluid to dimethyl silicone oil of 1:2. When the electric field intensity is 4 kV/mm and the shear rate is 3000 s-1, the maximum shear stress of the material is more than 9 MPa, and it has good temperature stability and anti-settlement performance. The STO electrorheological fluid was applied to the newly designed buffer, and the simulation test was carried out by using the fixed voltage, PID algorithm and fuzzy control algorithm respectively. The results show that the electrorheological buffer has the best anti-impact effect under the control of fuzzy algorithm, and the damping force and displacement peak value of the rear seat decrease by 30.5% and 19.1%, respectively. Good active control effect is obtained.
