Building the Energy Foundation for IoE Era
Toward 2040, alongside the evolution of 6G, the world is moving toward an Internet of
Everything (IoE) society where tens of trillions of sensors will be deployed across people,
buildings, cities, and industries. Continuous, real-time data from these sensors will become
a critical driver of economic and societal value. However, powering such a massive sensor
network with cables or batteries is neither scalable nor sustainable.
Installation constraints, maintenance costs, and the environmental impact of batteries
fundamentally limit the growth of IoE. Unlocking its full potential requires a new &
infrastructure-grade approach to power delivery.
History shows that transformative markets are built on foundational technologies. When
wireless power transfer is established as social infrastructure, data can be captured
everywhere—enabling smarter industrial operations, more advanced healthcare, and highly
efficient urban and energy systems. This shift will significantly enhance the speed and
quality of decision-making across the economy.
Aeterlink is commercializing practical wireless power technology to serve as this invisible
yet reliable energy foundation. By enabling sensors to operate continuously without physical
power constraints, we address a critical bottleneck in the IoE value chain.
My mission is to create long-term, global value through technology. Together with our
partners and investors, we are building the foundation for the next hundred years.
Let the future tell the truth.
