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?"   ","author_name":"Neural Implant podcast - the people behind Brain-Machine Interface revolutions","author_url":"http:\/\/neuralimplantpodcast.com","html":"
