Electronics Forum / Basics / March 2007Antena that can sense thermal Radiation from human body
Can i get some help in understanding or some help regarding sensing the radiation emitted by the human body, i recently sensed a very feeble signal from humans using a CRO, the freq was in the range of 60us .... and had its peak amplitude at around .2 - .3 V any idea .... how to extract info from this signal .... which peaks when some one goes near the antena, which we devoloped. ** Really desperate Groper Alert > Can i get some help in understanding or some help regarding sensing > the radiation emitted by the human body, i recently sensed a very > feeble signal from humans using a CRO, the freq was in the range of > 60us .. ** ROTFL What the heck makes this cretin imagine that a 16 kHz signal must be human HEAT ???? >.. and had its peak amplitude at around .2 - .3 V any > idea .... how to extract info from this signal .... which peaks when > some one goes near the antena, which we devoloped. ** Hey, dickhead !

So now you're going to start a cross posted thread to rally support against me? As if! Charles Manson has more friends than you _and_ way more social appeal. You really are a pathetic case phil. Don't even think for a minute that you are going to trash SEB the way you trashed those Oz groups. If need be, I'll post a FAQ twice a day that tells newbies about you. I guess I wasn't clear enough before, so here it is again: "Hey phil this is serious, can I talk to you for a second? This is SEB, where there are no stupid questions.

You're an idiot. My remarks about gapping switcher transformers is correct. We aren't talking about millimeter gaps here. More like nil gaps. They have their function, and you would be wise to learn what that function is. >However he has posted some useful stuff about HV windings. The most common mistake made by folks experimenting with small scale, high ratio step up, high turns count HV transformers are placing too many turns in a given secondary segment, allowing a breech through the insulation of the mag wire. Even the best double thick, high temp mag wire is only good for about 300 turns per segment. If one is not using a multi-segmented bobbin, one should place layers of tape between a certain number of turns, and another "set" of turns to keep the lowest voltage turn(s) away from turns that are at a much higher voltage. Volts per turn can be calculated to give the builder an idea of where to "layerize" his turns or step to the next bobbin segment. This is why a lot of Tesla coil builders space wind their stack coil. Depends on how well they have designed it though, really. A good double strength mag wire, and even varnishing of the finished stack is always a good practice (several coats). I know this, and I have yet to build one. I will though. I'll use it to reproduce myself (ala prestige) and send my double over their to whoop up on your lack of gapped core knowledge. Slap ya right in the face. Tee Hee Hee! >>>>>>On Mar 23, 2:18 am, MassiveProng >>>>>><MassivePr...@thebarattheendoftheuniverse.org> wrote: [quoted text clipped - 23 lines] > gaps.

Its a BAD idea, because either: 1) they have no clue*, or 2) are using a lousy control methodology that is susceptible to staircase saturation etc. There is a plethora (plague more like) of such "designs" out there, and all suck c.f. Current Mode Control (CMC). At worst, CMC is only slightly better than Voltage-MC (if it has input feed-forward etc), for a few topologies. for all other topologies it is a lot better. * OK, I can elaborate here. they may have done something real stupid, like forget that peak flux will saturate, but p-p flux is OK, except when you first turn it on (CMC cures this too). or they may have organised for too much flux, period. eg using Bsat(20C) c.f. Bsat(100C), and discovering when it gets hot they explode. or just using > Bsat(20C). or they may simply think a low Lmag is a good thing (its not). all of these things happen (I've seen them all), and all are indicative of a lack of understanding. I often use toroids for buck-derived converters - precisely because there is no gap. Big ones, too. of course for any boost-derived converter, its a coupled inductor, and the gap is a fundamental aspect of the design. >>However he has posted some useful stuff about HV windings. > [quoted text clipped - 3 lines] > through the insulation of the mag wire.

I'll happily pit my off-the-cuff (sans calculator) magnetics design skills against yours any day, loser buys the beer & pizza. But I wont challenge you to a game of pool, as I'd probably lose. Cheers Terry >dont you mean volts? If your volts per turn are what they should be, the 300 turns per segment come out about right. In some cases, it could be half that, but not usually. >>dont you mean volts? > > If your volts per turn are what they should be, the 300 turns per > segment come out about right. In some cases, it could be half that, > but not usually. OK, but doesnt that depend rather strongly on the shape of the segment, and of course the size of the core - eg a very large core so many V/T requiring correspondingly fewer turns, or a narrow yet deep segment, so the final turn is a long way away from the start turn. Cheers Terry >>>dont you mean volts? >> [quoted text clipped - 6 lines] >requiring correspondingly fewer turns, or a narrow yet deep segment, so >the final turn is a long way away from the start turn. Scatter winding is bad if there are too many turns because you don't know what proximities are involved, and most folks don't vacuum varnish on small scale switcher magnetics. So the depth of a segment doesn't give you the safety margin that keeping a good turns count rule does. All one needs to do is stop adding turns, add some tape turns, and then start another set of turns. Thus guaranteeing that you'll never have any two turns near each other that are to far apart in voltage. That is layered construction. Segmented bobbins usually don't give much room to go overboard on turns unless you are using some insanely fine gauge wire. >> I was hoping to "see inside" posts so I could delete all of those >> where Larkin keeps taking the bait... he just will not keep playing >> with MinimumDong :-( > > Said the habitual off-topic, cross posting, electronics groups > fucktard!

It also has a thermal shutdown which indicates that you are pulling MORE than it is rated at, dipshit. So go buy a 30 Amp charger if a charger is all you want, OR... Buy a f.cking supply that doesn't fold back on itself before its rated output is reached, OR do your requirements analysis better and realize that you needed a more powerful supply to begin with, you f.cking retard.

That wouldn't be thermal radiation; all of that is in the infrared for objects near body temperature. Unless your "antenna" is a sensitive IR detector, you're probably picking up something reflected from some source in the room. If that 60 microseconds is the period, that's a frequency of 16.666... KHz. What do you have running at that rate? A likely source is the horizontal oscillator of a TV set at 15734 Hz, a period of 63.557 microseconds. "Stephen J.

Hello Jiks, You might be experiencing what I call the Termen Effect which is the phenomenon enveloping the Theremin Antenna. It is possible to tune for proximity detection of your body presence up to six feet away. Distance is indicated as an audio frequency change of 20 Hz to several kHz near the antenna. It is a process a bit more complex than the detection of pure bodily emissions. lol My theremin webpage http://www.hwy79.com ,it's a musical instrument.

ANY matter at a greater temperature than absolute zero, emits IR radiation. Any antenna you have doesn't detect a body's temperature. More likely it detects already existing radio waves that the body increases the reception of when proximal to the antenna. Try it in an anechoic chamber. IR sensors are needed to detect temperature changes in an airspace. I do not see how an "antenna" can do this. >> Can i get some help in understanding or some help regarding sensing >> the radiation emitted by the human body, i recently sensed a very [quoted text clipped - 15 lines] > > I do not see how an "antenna" can do this. The same way an IR sensor does it. Infra Red and radio waves are both electromagnetic radiation. As you rightly said, all objects above absolute zero emit IR but they also emit radio waves and, if they are hot enough, visible light. It is a lot easier to use IR sensors, but if you have a sensitive enough system you can do it at microwave and RF frequencies as well.

The power received by an antenna due to thermal radiation is KTB, where K is Boltzmann's constant, T is the antenna noise temperature in K and B is bandwidth in Hz. Since Boltzmann's constant is very small (1.3806503E-23) the power due to thermal noise is received by the antenna is very small. The antenna noise temperature is the average of the noise temperature of everything the antenna 'sees' weighted by the antenna gain in that direction. Therefore you want a highly directional antenna so that the antenna beamwidth is completely filled by the person. You also want a wide bandwidth so as to maximise the power received. A dish antenna is therefore probably a good choice. The temperature of people is about 300K. Assuming an antenna bandwidth of 1 GHz you should get about: 1.38E-23 * 300* 1e9 = 4.14e-12 W = -83.8 dBm You will not be able to see that on an oscilloscope. To get it up to a detectable level you want a low noise, high gain amplifier after the antenna, then feed the output of the amplifier to a power detector and smooth the output of the power detector with a low pass filter. Now point your antenna at something with a very low noise temperature (the sky is good for this, about 10k) and record the output voltage after the low pass filter. Now point your antenna at a person - you should see a small change in output voltage. Another problem you have trying to detect thermal radiation from people is that the background also emits thermal radiation, often at a very similar level. I don't know what that signal you saw on your CRO was, but it doesn't sound like thermal radiation. It could be some sort of interference which is being picked up more efficiently by the antenna.

I DOUBT VERY SERIOUSLUY that in our world's RF RICH environment, that you or anyone else will be sensing body temperature related events from an RF antenna anytime soon. The "signal" if any is so far below the baseline noise that you will not be able to pick it out, if it exists at all. That is what IR detectors (resistor bolometers) and IR Imagers (CCDs and CMOS arrays) are for. And even those need cooling to reduce noise for high sensitivity applications. Many also need spectral filtering.

Same reason why an AM radio tunes differently while in your hand than after setting it down. That is why an AM radio tuned via remote locks onto the station better than hand tuning, and then walking away. >> It has been done, by me and lots of other people > > But what you sense are local RF reflections and amplifications, not > the temperature or any emission from the nearby test mass. The links I posted refer to systems which detect the thermal noise emitted by the object itself. Measurements of thermal radiation emitted at microwave and mm wave, as well as IR, are well established techniques for remote sensing from satellites. The techniques have more recently been applied to the detection of people for security applications. > Same reason why an AM radio tunes differently while in your hand > than after setting it down.

I'm aware of that effect, but the actual thermal radiation emitted by a person can also be detected at microwave frequencies with suitable equipment.

The IR spectrum contains more energy and so has long been easiest to detect. The rest if the MARKETING craopolgy you posted links to is about mm wavelength RADAR !!

Isn't that what I said in my post at 14:01 on 18 March 2007 > The IR spectrum contains more energy and so has long been easiest to detect. I also said IR was easier, See my post at 14:01 on 18 March 2007 > The rest if the MARKETING craopolgy you posted links to is about mm > wavelength RADAR !! Did you actually read any of them? The first two are PASSIVE, which means that they don't transmit - it's not about radar. The last one can be either active or passive.
