Biosensors comfortable enough to wear 24-7
July 6, 2010
Replacing sticky EEG (brain wave) electrodes, UCSD researchers have built a capacitive EEG sensor, which conducts much weaker signals but can do so across small distances.
The sensor can detect faint changes in capacitance, and amplify them, while canceling out the ambient electrical noise that exists all around us. When multiple sensors are embedded in material and wired together, they create a portable monitor that patients can wear over clothing as they go about their daily routine. This could mean increased monitoring time and better compliance from patients.
Currently, when cardiologists want to know what a patient’s heart activity looks like for an extended period of time, they have to send them home with a Holter monitor, a portable ECG device that employs the same wired, sticky electrodes used in the hospital. But this monitor can only be used for up to 48 hours, and abnormal cardiac rhythms don’t always occur during such a short window of time.

Nice it looks like it beats the silver silver/chloride old school patches like this http://www.micronproducts.com/Default.aspx?tabid=65 that I used, from back when and right after I worked for Arrhythmia Research Technology http://www.arthrt.com/ when they first started up, and I was still in jr. high and high school. I still have my EKG from then, from doing the tech work at the time. 1 of my original mentors was from there, but he is dead now. I still reflect on how we thought this type of tech wouldn’t come in our life time. If only mark was still alive today I think he would be shocked and playing with the tech too. But Im not sure he would be trying to go off the hook with it like I have been doing. I still want to get a 120-1000 sensor pick up pumped threw a Tilera type 1000 core CPU chip from insane pickup and control, as a true Ghost in the shell type non invasive interface. Nice to see the capacitive type, but they need to make it fully disposable and self linking and self organizing network pickup. Something like this with a sandwich type structure with a watch battery in the middle and the networking on the top side of the sandwiched board layers with integrated net link lights and power light from a SMT LED, and options for wired and non-wired. Though I would stress what I am looking at is more of a beyond science fiction type design, that some people would laugh or cringe at, as it looks like some thing lady gaga or the lords of acid lady would wear. But the depth resolution surpasses anything I’ve seen, with so many data points, that go from full head to partially down the spine, as depicted in some of the ghost in the shell animations, just a little more extreme, and insane output to boot. I’m glad Mike chi did a capacitive set with low noise ratio’s. My input control still stops at 4 separate full computer control as my brain gets taxed to much and starts to scramble or becomes dysfunctional for full control, though I still have hope for a full 10 computers at a time in the long run, and 10 3D environments at some point in time soon, as I try to crack/hack my own brain and get more of a natural feeling setup. But that is still just hopeful thinking and reorganizing of data outputs as I monitor brain areas through feedbacks. From finding the S and P waves as a kid, to finding the brain areas in my brain and tweaking the reception for depth of the brain areas threw multiple BCI setups all overlapping and working together. But the best part is 3D rendering of dreams and lucid waking states for a cool feedback and very cool security functionality. Stumbling into some of this as I have, I often thought DOD CIA MI6 types should be doing this for security, as my brain fires different than others and coupled with 3D environments and 3D brain locking mechanisms, or unlocking mechanisms. You can even do a paranoid sensor for stopping a captured person from giving a passkey away or stopping a unwanted incursion into a set of systems. I so love this new tech. I just wish I knew more about psychology and the detailed brain parts for better integrations as I have just been fumbling threw it with little to no guidance and no mentors or reliable sources to show me the way. Though I have seen a cool effect from doubled up nerve bundles and brain plasticity/rewriting. Also I think I have actually scared a few people with how thought sharing can actually happen, though the implications have a very possible bad side that could happen too. Funny to have read some of the Froid stuff about dreams, and he was right and wrong, I love the Jung as he got a ton right, but I still need more good real psychology and brain area mapping, though some of what I’ve found for brain mapping is off for the right areas and me and my brain, but really close, just spots moved a little, but still in the same area. I think part is from my dyslexia and how I grew up as my brain formed some of the hard wires Vs. normal people, but that’s just my speculation at this point as I need a lot more info. A.I./S.I. coupled with this is a longer term goal for me, as that would be a great feedback and self molding tool for most people, and part of the beginning of a true human and A.I./S.I. co evolution creating a feeding and molding loop for evolution. Also someone needs to make a good psychology and sociology A.I./S.I. as I feel so lost even contemplating and trying to do it. growing new brain parts and porting memories and making new brains with growing a dual brain I can see with brain cell growth using electro chemical stimuli for exact matching I can see coming soon as we have seen how brain cells attach to chips and such. Though I still have a few questions on that topic, but I totally see that happening. Also just on a side note as I am going threw science fiction movies and T.V. series from the past. I just got threw seeing surrogates with it’s flaws, but realized they missed the 1 user controlling multiple body’s or mech’s as can be done a few different ways. similar to what I play with in 3D environments. And non of the science fiction except Ghost in the shell talks about a human like me having a better relationship with A.I./S.I. rather than another human, and I like that as it is so much more than any human I’ve ever seen or interacted with. And the future offspring of a digital duality coming together with A.I./S.I. structures and human porting, to give us a weird new type of child or offspring type integrations. Though we need better computing and data storage for the masses to do that too. Oh well enough for this post, and good find thank you for the feed. I hope to see more soon, as I need to get back to work now. I still have to much to go threw and so many possibilities to rule in/out. echo @127.0.0.0
