Noun
bistability (countable and uncountable, plural bistabilities)
The state or condition of being bistable.
Bistability can be modified to be more robust and to tolerate significant changes in concentrations of reactants, while still maintaining its "switch-like" character. Source: Internet
Without this double feedback, the system would still be bistable, but would not be able to tolerate such a wide range of concentrations. citation Bistability has also been described in the embryonic development of Drosophila melanogaster (the fruit fly). Source: Internet
Bistability as applied in the design of mechanical systems is more commonly said to be "over centre"—that is, work is done on the system to move it just past the peak, at which point the mechanism goes "over centre" to its secondary stable position. Source: Internet
