Serious answer to a facetious reply: I’d imagine there has to be some level of software involved if it’s pulsing, even if it’s rudimentary or low level. I also wonder what it does in terms of the bodies demands such as during physically intense activities. I’d guess that it doesn’t which, along with the 4 hour battery life, probably answers why it’s a stop gap and not an alternative at this point. Still awesome though.

Fascinating, and awesome for people in need, but a whole new level of battery anxiety.
