I'd like to know more about how it's powered. Didn't see anything on that. Seems like it's powered by proximity to that purple square.

- XorNot 12y agoThey say it's energy scavenging - like passive NFC tags essentially.
- tkinom 12y agoAgree, the whole demo looks like an passive NFC tag. What's new here?
- Stwerp 12y agoIts far-field, so it couples completely differently than NFC tags. Also, NFC communicates by reflecting signals, this device communications by active transmission (according to the article, I haven't read their paper yet). What's new? Its tiny, and I'm very curious how they got that an oscillator to work at extremely low powers. But, it is really just an extension of RFID/NFC/IoT miniaturization work. But then again, just about everything starts out that way.
- Bud 12y agoThat's explained in the article: "a receiving antenna that also scavenges energy from incoming electromagnetic waves".
