 Enabling sustainable sensor networks with RF backscatter

摘要

We need affordable and innovative sensing to assist in tackling global-scale problems like sustainably feeding the next billion. RF backscatter systems such as RFID are well-known in the sensing community because of their low power consumption. 这个演讲 explores how we can enable robust indoor/outdoor RF-backscatter sensing by leveraging advances in low-power embedded systems. It will describe the challenges faced in low-power and sustainable sensor networks, and provide an overview of an outdoor radar backscatter sensing system that uses RF to measure soil moisture with accuracy comparable to state-of-the-art commercial sensors, but at a fraction of the cost. 还将讨论最近的情况 work on renewably powering outdoor sensor systems via energy harvested from non-traditional 比如微生物.
