Description
Guoyuan Zhang and colleagues build a mechanical ion transistor that switches ion flow with unusual sharpness. Living touch channels open once push passes a set point, flipping fast between open and closed states. The team copied that trick with narrow graphene channels whose charge can be tuned by an electric gate.
Under rising pressure, the flow of current through the channels rose in steps rather than in a smooth line. That step pattern gave a very low swing value, the mark of a crisp switch. Salt water filled the test cell on both sides, with electrodes tracking the pressure-driven current. Charge blocking inside the tiny channels helps explain the sharp steps. Such switches could serve in sensors and in computing parts that work with ions instead of electrons.
