An All-Digital Ambient Backscatter solution powered by Energy Harvesting

This work presents the development of an all digital backscatter system powered by an energy harvester circuit. The system is composed by a solar panel as energy source and a microcontroller unit (MCU) that processes the data coming from any sensor while changing the state of a digital IO pin to perform backscatter communication. The system achieved a bit rate of 5 kb/s sending information provided by a temperature sensor.
