Now a worn or damaged battery can be safely bonded down as it normally would with a PSA (pressure sensitive adhesive), but then after applying some 30V for a couple of minutes ions in the adhesive cause it to become easily and safely removable/repositionable.
> Do you need a conductive substrate on both sides to apply the release voltage?
Yes, you attach VCC to the substrate you want to remain bonded and GND to the substrate you want to detach.
> How available is it for purchase if you aren't Apple or Samsung?
You can just call up your usual 3M distributor and request it. It's over $2,000 for a 100 meter roll so it's not something you'll usually find in stock at your local Grainger but it's not some super-secret material only available to the biggest manufacturers.

I always had the feeling that the Cloudflare CAPTCHAs discriminate in various ways, for instance I would see them much more when I was browsing on a Samsung Galaxy tablet than when I was browsing on an iPad. They disproportionately affect the disabled and I wouldn't be surprised other vulnerable populations.
If I had anything to do with it having a CAPTCHA or a GDPR popup would be an immediate WCAG fail at A level.
