This podcast's purpose is to bring together the field of neuroprosthetics/brain machine interfaces/brain implants in an understandable conversation about the current topics and breakthroughs.

We hope to replace needing to read scientific papers on new research in an easy to digest way.

People can share thoughts or ideas to facilitate 'idea sex' to make the field of brain implants a smaller and more personal space.

Francois Ladouceur is a University of New South Wales professor teaching and researching integrated optics, silica and diamond-based photonics, optical sensing networks, and photonics-based brain/machine interfaces

Top 3 Takeaways:

  •  "it's a liquid crystal-based transducer that can transduce an electrical signal into an optical signal that we can carry the away from the place of measurement"
  • With electrical-based electrodes making the devices smaller increases the impedance degrading the signal which doesn't happen in LCP based electrodes
  • "We have built a chip, which is bidirectional, it can read the action potential and it can stimulate the neuron. Again, entirely passive. It requires no electrical input. It does not dissipate energy."

0:30 "How did you get on this podcast?"

3:00 Is another advantage the lack of heat generated?

5:30 "What are the bio compatible properties of liquid crystal?"

7:00 "What are some advantages of this over other techniques?"

10:15 "How does the multiplexer work?"

15:15 "What would be the minimum width?"

19:00 "You haven't really published too much about this, but you said a big paper is going to be coming out?"

21:30 "It's really just for sensing, you couldn't stimulate with these, right?"

25:00 "When did this technology originally come to your mind?"

27:15 "Is there anything that we didn't talk about that you wanted to mention?"
