> The devices produce a sustained voltage of around 0.5 volts across a 7-micrometre-thick film, with a current density of around 17 microamperes per square centimetre.
How good is that? They talk about powering smart watches with this, and other personal electronics. So it sounds like it’s within range of a useful amount of power?
