The same way as cut frets, six wires to the fret, one pro string.
Need a material with a high resistance prob somthing like 100k/cm.
The advantages would be; there are no gaps in the fret, you can sence bent
notes and easier mounting.
The big cons are obviously the price and extra implementation problems
(software).

More a thought experiment than a practical solution realy, although it might
work if you can make the frets.
