Technology uses plant biomass waste for self-powered biomedical devices:

An innovation turning waste material into stretchable devices may soon provide a new option for creating self-powered biomedical inventions.

A team from Purdue University used lignin to create triboelectric[*] nanogenerators. TENGs help conserve mechanical energy and turn it into power. Lignin is a waste byproduct from the pulp and paper industries, and it is one of the most abundant biopolymers on Earth.

[...] Wu said the lignin-based triboelectric devices also could function as self-powered sensors to detect and monitor the mechanical activities from the human body in applications such as health monitoring, human-machine interface, teleoperated robotics, consumer electronics and virtual and augmented reality technologies.

    So chances are this discovery will be used by Chairman Pooh to repress the Uighur muslims in Hong Kong,

      Nice diversion, Mr President, but China doesn't use its police to kill black people. #BlackLivesMatter

    Make a bunch of nanogenerators and use them to power a bunch of air conditioners to cool the planet. Since they are powered by lignin they won't add to greenhouse gases. This development gets the St Greta seal of approval!

    Boomers forced everyone to stay home at gunpoint to give Boomers a safe space.

    Boomers forced every business to close at gunpoint to give Boomers a safe space.

    Boomers forced everyone to wear face masks at gunpoint to give Boomers a safe space.

    Boomers caused the worst economic depression in history to give Boomers a safe space.

    Whiny entitled Boomers are the worst generation ever to live.

    No longer.

    Boomers must be made to pay with their lives for crimes against civilization.

    The Final Solution to COVID-19 is to exterminate every Boomer.

    So... using plant matter to power biomedical functions.

    Sounds like what we dd before we started consuming Big Macs and french fries 24/7.

    How bout we eat the plants and don't clog up our arteries with so much beef fat then we won't need Chinese grad students to invent plant-based polymers to keep our narrowed arteries from completely closing shut.
