Wirelessly Powered Sensors

I am currently in the process of developing a set of extremely low power wireless sensors that run off of scavenged RF power. The sensor is able to run off of a carrier of -6.0 dBm at 2.4 GHz and relay data it gathers from an enviornmental sensor by backscattering the signal that energizes it.

I have written a conference paper which I have submitted to the IEEE about the improvments I have made to the circuit topology. I cannot publish the paper prior to its acceptance/denial from the conference. If you would like a pre-print copy please reach out to me by email.

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

Below are photos of older revisions of the sensor with its antenna attached.

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.
