Abstract:

Millions of people worldwide use smartwatches and fitness bands to monitor health metrics such as temperature, sleep patterns, heart rate, and travel history, which are vital for early disease detection. However, these devices require a continuous power supply, as interruptions during charging or battery replacement can reduce data accuracy and reliability. Battery issues are prevalent in portable devices like smartwatches, fitness trackers, and Bluetooth earbuds. Ambient energy harvesting offers a promising solution, utilizing environmental energy sources such as vibrational, thermal, pressure, solar, and radio frequency (RF). Among these, RF energy harvesting is particularly advantageous due to its weather independence and continuous availability.

The proposed keynote talk highlights the transformative potential of various ambient energy harvesting (AEH) technologies, focusing specifically on recent advancements in RF Energy Harvesting (RFEH) technology for next-generation smart wrist wearable applications. Further, the talk emphasizes interdisciplinary approaches, combining antenna, rectifier, and power management unit to overcome challenges like efficiency, miniaturization, and scalability. Attendees will gain insights into the future of autonomous wearable devices and their role in smart healthcare, and sustainable innovation.
