An All-Digital Ambient Backscatter solution powered by Energy Harvesting

Abstract

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.
