Pressure control achieved by the MRE valves. (A) presents the schematics of the pneumatic and electric circuit used to control the pressure within a soft pneumatic actuator. (B) shows the electronic equivalent of the pneumatic circuit used for pressure control. (C) shows the step response of the pressure within the soft pneumatic actuator controlled by the MRE valve. (D) shows the different amount of bending of the actuator under different desired pressure values.
