Hello,
I constructed a 'memdiode' one time in the past. It started out as a diode
with about 0.7 volt drop and ended up as a resistor with infinite resistance.
This happened just by turning the TV set on one day and blowing one
of the low voltage rectifier diodes
On the more serious side, i have to think about what Nigel said too because
after reading about superconductors changing America back in the 80's i
still do not own one device that has a superconductor in it. It's all in the
big labs and the LHC and stuff like that.
If it does work out in the long run and we actually see some of these
devices, it will be really great, except gee i'll have to come up with
another Spice model somehow...probably with an integrator and FET
or something like that. Who says it can't be built with other circuit
elements? Not me. We can build much more complex devices out
of other more basic circuit elements so there is no reason why we
can not construct that too. Heck, it should be much more simple
than some magnetic models.
Still, it being a single device controllable with a simple current is
very nice. I can see the apps coming if it all works out...but i
also dont see any repeatability data...how well do the properties
repeat? If this works out too, then one app would be a very
simple battery state monitor (battery gas gauge), to monitor the
state of charge of a typical cell. But then, how much energy
will it require to run. How long before the chemical activity
starts to diminish.
There may still be some hurdles to get over before we see anything
reaching the production lines.
