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.

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