What key feature characterizes the battery-free wearable developed by University of California, Irvine researchers?
It uses radio frequency (RF) energy harvesting to operate
The battery-free wearable health monitor developed by researchers at the University of California, Irvine (UCI) represents a major departure from previous models because it completely eliminates the need for manual charging or battery replacement. This solves a critical failure point in maintaining long-term monitoring continuity. The device achieves this power independence by utilizing radio frequency (RF) energy harvesting. This mechanism allows the monitor to draw the necessary operational power directly from the ambient RF signals present in the surrounding environment, thereby enhancing user adherence by making the device nearly invisible and eliminating the maintenance burden typically placed on the patient.
