A clutch is a mechanism for controlling the transmission of rotation, which can be either engaged or disengaged.
An electrorheological clutch (ER clutch) comprises drive and driven members, generally parallel to each other, that can be selectively engaged by the application of a voltage to an electrorheological (ER) fluid. The ER fluid is used as the coupling between the input and the output (drive and driven members). The clutch acts as a power amplifier and the effect is fast (of the order of milliseconds) and reversible.
