Do brain implants get firmware updates and such wirelessly?
- fapjacks 9y agoNo, they do not. Any device upgrades (including e.g. firmware) require surgery.
- maxxxxx 9y agoMy company produces brain implants. Technically you can upgrade the firmware wirelessly (we do this in testing all the time) but nobody wants to take the responsibility for doing that with patients. With more RAM available I think wireless upgrade will be the standard in a few years.
- ams6110 9y agoWireless updates viewed as riskier than surgery? Or is it just that the liability moves from your company to the surgeon?
- maxxxxx 9y agoFor a wireless update you need to be able to store the new firmware in a temp area, verify it and then activate it. Old devices don't have enough memory but that's changing. Also, most new firmware needs new hardware features so this capability may not be that useful in practice.
- nobodyorother 9y agoIt's more than liability, reducing physical access requirements opens up a much larger attack surface. I know if someone's opened up my skull. I assume everyone has some sort of multi-band wireless transceiver in their pocket, because that's a cell phone.
- vxNsr 9y agoCould you speak to the reason there isn't any mention of shielding, or why to layman that seems like the best approach but actually isn't?
- maxxxxx 9y agoI don't know the details but the biggest problem seems to be the interaction of the pulse generator with the leads. You can't shield that away. It's more complex.
- PhasmaFelis 9y agoWireless updates obviously have major security issues, but I wonder if there's a compromise that doesn't require surgery. Induction, perhaps? Updates transmitted through a wired induction pad pressed against the skin above the device?
