Batterfly: Battery-Free Daily Living Activity Recognition System through Distributed Execution over Energy Harvesting Analog PIR Sensors

In recent years, the use of energy harvesting (EH) sensors has led to the proposal of activity sensing systems that are easy to install and do not require maintenance such as battery replacement. In this study, we aim to construct a system that can not only sense but also recognize activities of daily living (ADLs) using only power generated by EH sensors. To achieve this goal, in this paper, we p...
