Implantable electronics that can deliver drugs, monitor vital signs and perform other health-related roles are on the horizon. But finding a way to power them remains a challenge. Now scientists have built a flexible nanogenerator out of cellulose, an abundant natural material, that could potentially harvest energy from the body—its heartbeats, blood flow and other almost imperceptible but constant movements. Their report appears in the journal ACS Applied Materials & Interfaces.
