Powering Future Mobile Phones Through RF Energy Harvesting

TL;DR

This paper reports preliminary measurements of RF energy harvesting from mobile phones, demonstrating the potential to power future phones wirelessly by capturing energy emitted during normal use.

Contribution

It provides initial empirical data on RF energy harvesting from commercial mobile phones, highlighting differences between manufacturers and potential for wireless charging.

Findings

Samsung phones harvest more energy than Asus phones.

Approximately 1.53 joules can be harvested per day.

RF energy harvesting is feasible for powering future mobile devices.

Abstract

In this paper we present the preliminary measurement results of harvesting radio frequency(RF) energy from the mobile phones. The aim is to revolutionize the way mobile phones are being charged and paving a way of charging the future mobile phones through RF energy harvesting. In order to measure the amount of energy that can be harvested, mobile phones from two different manufactures namely Asus and Samsung have been used. It was shown that depending on the manufacturer it is possible to harvest 1.53 joules amount of energy per day.
