You only get tiny amounts of energy out of energy harvesting in general. The press release [1] links to a video that drives a black and white LCD display [2]. You really should look at that video to see what the tech can do. You can't power smartphones with that.
Still energy harvesting is pretty interesting for e.g. sensors. There already are zigbee light switches that work through energy harvesting (e.g. [3])

- brudgers 10y agoI'd think of as energy recovery more than energy generation. The analogy would be to regenerative braking on an electric vehicle. Thermodynamics still applies, but the device becomes more energy efficient at the macro scale. Here the relationship to energy recovery seems to be that what is displayed on the screen is related to the amount of swiping. I'm not sure it's going to change the world, but I'm not certain it isn't worth pursuing either.
- legulere 10y agoThe power generated by this is probably several magnitudes smaller than what a phone uses. What's the use when your phone gets e.g. 0.1% more energy efficient? Regenerative braking makes sense because it's a lot of energy and you can use the motor as a generator.
