Y'figure, a grid of wires embedded in a *** of silicone? The wires
alternate so like a 'fridge magnet, each pair of wires generates some
force. (In case you haven't noticed, those flat flexible 'fridge magnets
are made with alternating N-S layers. You can take two and slide them
across, they cog as the N and S's oppose.)

Yes, looks that way, maybe that is how it moves too,
use 2 of those sets with a slight phase shift.


Then you could use a couple of these pads with linear actuators to make a
climbing action, or just put pads on your hands and feet ala Spiderman. It
would be really cool to put an HV charger on your belt and a pushbutton
inside each pad to discharge it, so you just press your thumb / toe to move
that limb.

I have seen at TV program where they tried to walk on a ceiling with magnetic shoes.
Safety ropes of course, they used a professional acrobat, but even he
had big problems putting his legs _up_ to put the foot back again,
as then he had to bend his other leg against gravity (and pull up his weight
that way).

But hey, give this thing a paint brush, and I have got some work for it :-)



The hardest part may well be structural integrity of the pads, especially
enough to support weight, while being flexible enough to conform to smooth,
rough and curved surfaces.

Seems like something one could build oneself.
Amazing force too!
