Multiple applications: The magnetoelastic generator can be used to power health monitoring devices, as well as act as a cardiovascular monitor. (Courtesy: Nat. Mater. 10.1038/s41563-021-01093-1) ...

Previously, magnetoelastic generators had been constructed out of rigid metal alloys, which were too stiff to be comfortably worn on the body.
