The lack of details is infuriating. It makes it sound like they implemented a compliant bluetooth chip at 1/1000th the cost size and power of commercial solutions.

from skimming the paper, the big advance here is a moisture/oil resistant "triboelectric nanogenerator", which generates energy from touch or vibration, and they could get stable power out of it long enough to do a bluetooth transmission with a standard (conventional) bluetooth chip (an adafruit bluefruit, apparently)

the moisture/oil resistant part is a big deal for actually using it in the real world

The actual paper [0] does have some decent details, though it is somewhat heavy.

Too bad they published it through Elsevier. I would have liked to read their paper.

That's what sci-hub.tw is for.

Doesn't appear to be there yet. See https://sci-hub.tw/10.1016/j.nanoen.2020.105301.
