This technology is called galvanic vestibular stimulation and I found a relatively recent paper that actually tried to reduce VR motion sickness using it https

That's neat, would love that for VR as I can easily get sick from motion that isn't 1:1 with IRL movement.

I experimented with this (counts fingers) OH! Ahem. Uhm, 8 years ago. https://www.linkedin.com/pulse/i-just-hacked-my-brain-sean-mcbeth https://www.linkedin.com/pulse/i-just-hacked-my-brain-sean-m... Excerpt: "The sensation is undeniable. The direction of the tip is dependent on the direction of the current, as evidenced by just swapping the electrodes. Obviously, since these were batteries, this was a DC current. Sensation grew stronger over a brief period of time until it saturated. It sort of feels like someone pushing or pulling you over, except there is no tug on your arm. The ramp-up in the feeling made me think of charging a small capacitor." I remember it pretty clearly even today, which is weird because I tend to but remember this very well, but maybe it was just the excitement of the experiment. It was a relatively strong effect, and it was fairly easy to achieve (of I could do it with my crude setup, a real product should have no problem), but there were some distinct issues. First of all, there was a lag in response, and it was a pretty large one. IIRC, it took at least half a second before I started noticing any change after turning on the current. Next, it was fairly binary, and single axis. I could tilt left/right, but that was it, no front/back. It took time to ramp up to full tilt, and then I could only achieve about 50% tilt. I briefly forgot what I was working with and thought I might try to limit the sensation by pulse width modulation of electrical signal. That was quite a shock! I mean that seriously! Anyway, I came away from the experience feeling slightly nauseous and that GVS was too limited to work out.
