Does there exist any device or technology where something like a FET channel exists that is an E field controllable switch but unlike a FET, the device can be made long (like a small width long length rectangle , ideally flexible to some degree) and the conducting part can be swept linearly along the way.
Like switching the E field in sequence modulates where along the length of the device the channel exists, so that a current path can be controlled.
You see unlike in a regular switch I do not intend to switch it off completely, it can stay ON all the time , just the current path needs to be moved around spatially in a linear way.
I cannot do this with regular discrete MOSFET's because they are discrete and even though making a long line of them that connect two conducting surfaces still as I switch them in sequence the current path moves in steps not in a sweeping action.
Ideally if there was one long FET channel then such a thing could be done.
Is there anything close to what i ask, and out of curiosity can semiconductors like FET's be made long and large , instead of having small dies within epoxy molded packages?
