Wirelessly Powered Sensors

I am currently developing an extremely low power wireless sensing platform that run off of scavenged RF power. The current version of the sensor is able to continuously run off of less than a tenth of a milliwatt of power at 3.3 GHz. It relays data it gathers from an enviornmental sensor by backscattering (reflecting or harvesting) the signal that energizes it.

I have written a conference paper which I am preseting at the IEEE International Conference on Electromagnetics in Advanced Applications. I cannot publish the paper prior to its inclusion in IEEE Xplore. That being said, if you would like a pre-print copy please email me and I can send it to you.

This work was undertaken as part of an independent study + research (ISR) project at Olin College of Engineering.

This research is a work in progress. More updates to come…

If you too want to experiment with backscatter radio, I sell a backscatter radio module on my store page.

Below is a small photo gallery of the previous two revisions of the sensor.
