Positioning in challenging environments

From driving, to crop harvesting and timing in the financial markets, many aspects of our modern lives are reliant on GPS. But, although they are everywhere, high frequency radio waves have a flaw. They are blocked by solid objects – like buildings – so they can’t reach everywhere. Imagine if there was a different approach. …

Brandon Lucia: Energy Harvesting Computers: Extracting Energy from the Environment

In my lab, we’re developing the basic technology to support what are called “energy harvesting computers.” These are devices that can perform computations, sense their environments, and communicate using energy that they extract from their environments. We can make devices harvest radio waves or use solar energy. By powering these devices with energy extracted from …
