Wearable multimodal monitoring systems deliver continuous insight into patients' health status but are constrained by power needs. Next-generation artificial intelligence-enabled wearable microgrids can drive sustainable energy harvesting, intelligent budgeting and adaptive management for autonomous, on-demand power delivery for wearable devices.
In both applications with different modes of operation, the wearable microgrid system—with its complementary and synergistic BFC-TEG harvesting and commensurate SC pairing—was able to deliver both fast-booting and extended-harvesting to ensure the autonomous and sustainable operation of the wearable platforms.
Being power hungry, edge-computing devices need to find a smart way to be combined with wearables to balance power generation and AI computation. Moreover, wearable microgrids face motion artefacts, as users would want their daily activities to proceed without considering the presence of wearable sensors.
The microgrid canstore and regulate the harvested energy via efficiently paired SC modules to efficiently power wearable applications such as an LCD wristwatch and a sensor-ECD system.
This shirt harvests and stores energy from the human body to power small electronics. UC San Diego nanoengineers call it a "wearable microgrid"—it combines energy from the wearer''s sweat and
The microgrid aims to create a self-sustaining power source that can charge small electronic devices such as fitness trackers, smartwatches, headphones, and even medical sensors.
