“…Depending on fluid flow and applied voltage, MRF applications can operate in valve (flow), shear, squeeze, and pinch modes. Usually, the fluid is contained within two plates and may experience different operating conditions (Arteaga et al, 2020a), as shown in Figure 6. The magnetic field controls the flow resistance for the valve mode (Figure 6(a)) (Arteaga et al, 2020a;Nguyen and Seung-Bok, 2012).…”

“…Usually, the fluid is contained within two plates and may experience different operating conditions (Arteaga et al, 2020a), as shown in Figure 6. The magnetic field controls the flow resistance for the valve mode (Figure 6(a)) (Arteaga et al, 2020a;Nguyen and Seung-Bok, 2012). In this case, the poles are stationary, and the magnetic field is adjusted to control the pressure drop between the inlet and outlet and, therefore, the resistance to fluid flow (Rossa et al, 2014).…”

“…However, the external force is imposed perpendicular to the poles, compressing the fluid (Rossa et al, 2014). A force is applied to plates in the same magnetic field direction, and the plates are moved toward or separated from each other (Arteaga et al, 2020a). Here, the MRF can be subjected to dynamic or static loading (Nguyen and Seung-Bok, 2012).…”

“…The wide use of the Bingham model in the prosthetic field is due mainly to its simplicity, effectiveness, consistency of data in experimental analyses, and good linearity (Arteaga et al, 2020a; Ghaffari et al, 2014; Imaduddin et al, 2013). The simplification results from the assumption that the observed elasticity of the accumulator has low stiffness and linear characteristics (Seid et al, 2016).…”

“…Subsequently, several prostheses (b–d) were developed using commercial MRF devices (Arteaga et al, 2018b; Ochoa-Diaz et al, 2014; Xie et al, 2010). Currently, studies focus on the design, optimization, and control of MR devices: (e) Thermal analysis of an MR knee brake (de Andrade, 2021), (f) magnetic analysis of a single-leg MR shock absorber (Arteaga et al, 2020a), (g) comparison between MR brake models with and without optimization for one knee (Mousavi and Sayyaadi, 2018), and (h) experimental test of control of a prosthesis with MR damper (Zuo et al, 2021).…”

Magnetorheological fluids (MRF) are intelligent materials that can vary their yield stress in response to an applied magnetic field. This characteristic, combined with active and multifunctional control, allows the development of actuators with fast response time, low energy consumption, long service life, and reduced dimensions and weights. Various studies have been conducted to improve MR dampers in prosthetic applications, including knees, ankle-foot, hands, and sockets. Here, we present a critical review of the progress of MRFs in the prosthetic field. In addition, research in prostheses’ design, optimization, and control of magnetorheological actuators is investigated, along with MRF modeling, mode of operation, type of MR actuator, classification, and working principle of MRF-based devices. Although MRFs are considered promising materials for designing novel prosthetic devices, this review shows that applications have been predominantly focused on lower limb prostheses. We conclude by discussing possible future applications and challenges that must be faced to enable and improve commercial applications based on MRF technology.
