In the project "battery-less sensors for energy-efficient buildings" we will use ambient backscatter to collect data from a huge amount of sensors. Ambient backscatter is a new paradigm-shifting technology that enables sensor nodes to communicate with RF signals already present in the environment, for example, Wi-Fi signals. Battery-free sensors enable additional energy-savings in buildings since they enable more measurements points as the operational costs of ensuring that all nodes maintain enough battery power to fulfill their tasks drastically reduces. Furthermore, sub-optimal energy control caused by missing sensor input (due to depleted batteries) is avoided and new applications such as fine-grained localization in smart homes are enabled which have further energy savings potential. We will devise the hard- and software for ambient backscatter. We will test our solutions in lab and real environments piggybacking on existing deployments that we enhance with our technology.
