Yes, there will be some small current. If you care about human body protection, mechanical relay will be better option.
It seems that all kind of scan process to see accross the human body should necessarily to generate a big amount of energy. There are different wavelenght, different scan schemes and different sensors to detect the radiation not absorbed by the body, but all these porocesses are somehow invasive in the sense that they are (...)
Hi All, I dont know if im posting my questions in the right place but ill give it a try :) Im starting to work on a new product and im looking for a transceiver that can transmit to 250m (line of site) with data rate 2KBps . the transmitter need to placed on a human body (wearable) and need works on battery. also i (...)
Hi! I'm starting to use CST for bioelectromagnetic simulations and I need to use human models of the whole body. I am looking for some general information (basis, advantages, disadvantages...) about the difference between CAD and Voxel models since CST allows to import models in both formats. Can anyone help me? Thanks!
It might help to think how you would describe a moving human, in terms of geometric shapes. Start with the scene as represented by a grid of pixels. A human generally is a tall rectangular mass of pixels. The head is a smaller oval mass, at the top of the body. Face and hair are often different colors. Arms are long rods, (...)
Hello everyone, Anyone can help me to solve my CST design for SRR antenna. I try to simulate my SRR antenna by using coaxial probe. But the problem occur when i place my antenna with different layer of human tissues body. Seems like this antenna not working well if I do simulation with skin,fat,muscle and bone layers. I change material of (...)
Your description is vague. By "box" you mean bounding box? the background box in the cst? How is this box created that prevents putting/attaching other objects on it? By "directly on it", do you mean that it has to make perfect contact? if it is an antenna, you don't need it. Even for other boundary condition problems small air spacing wouldn't aff
I was wondering if anyone has created his/her own voxel model for human body compatible for CST? I know that a member "alecacci" long time ago has created a file but it is no longer available, hbm_2629.rar. The only attachment that is downloadable, "human body model.rar", just has some and *.mesh files that (...)
Hi, specifications need values.. The problem is not "touching" a pin, but there may be an ESD voltage with a specific capacitance and a series resistor. There are several models like "human body model" that fits best your needs with "touching". Charged device models and different machine models... So you need to know: * vol
Are you trying to find a dead part on a human body because it is colder than the alive parts of the body? Do you think that diabetes or cholesterol will cause poor blood circulation to a part of a human body causing it to be cooler than the warmer parts with good circulation?
Hi all, human body tissues are characterized mainly by three properties Permittivity, Conductivity and loss tangent.. 1)Since the body tissues are dielectric, how it could have conductivity ? For all materials in the material library of HFSS, we have mention these values..(Permittivity, conductivity,loss tangent e
Just a guess. I would suggest searching Autocad/3Dstudio/Lightwave/Softimage models in 3D CG groups. In 90s I've seen pretty detailed models of human head with parts in separate models. I mean separate ears, eyes, noses, teeth. I believe there are a lot of them because CG guys like different faces blown up and draw every time everything from the sc
Hello frends, Can carbon nanotube sotre human body temperature, If yes, then how much it can able to store, or that much energy can be helpfull for any purpose, Please if any one had gone through it, then please help me. Thanking you alot...
The main physical attribute of these sensors is the ability to be sterilized by autoclave equipments for high pressure and temperature too far beyond that which it was designed to operate in the human body. On medical equipments, what you say as "sensor", we could better technically define as a "probe", due consists of an apparatus (...)
Nameplates convey ratings. Not all ratings can be supported simultaneously in all cases. Until you understand the basis of them there's no point in electrical lawyering, Ohm's or otherwise. You seem not to understand the nature of the human body as load, in the context of electrocution. You make (...)
It has. The standards for ESD sets voltage levels and source characteristics (such as human body model (HBM) or machine model (MM) ). Both the model and the voltage level may be specified in the product's datasheet. charge device mode(CDM) is the other ESD performance index besides the HBM (...)
i am beginner using feko but i just want to draw human body in feko to simulate ,any one who know how or may be help me if there is any other 3D software so that i can draw and import to feko.or any one who have the file so that i can import direct
Skin and human body models in general are developed for calculating SAR (Specific Absorption Rate). SAR is a measure of the rate at which energy is absorbed by the body when exposed to an electromagnetic field, so there might be possible to find a model that consider the human body (...)
I am using K type thermocouple with ad595.The resisistance between the two terminals of thermocouple is 8k.

Hi I want to calculate the SAR for microstrip antenna with coaxial cable on human body phantom with HFSS. I dont know how calculate the SAR with HFSS. and I dont know how a microstrip antenna with coaxial cable are placed on human body phantom. please help me:cry:
Hello. I am doing a prototype to register vibrations created by the human body by the use of 2 accelerometers. Everything works fine and it is able to register the vibrations that is created by the heart. I have a high pass filter to filter out the DC component of the signals at 0,5Hz but no low pass filter so this introduces some noise (...)
antenna is something that happens while getting fabricated esd occurs after chip gets fabricated when a machine/human body touches the IC. hope this is useful
Which ever potential DC or AC is hazrdous to humans beyond a certain level. It highly depend on diffrent body resistances through which the potential is grounded. By the way as AC is fluctuating in cycles, is less harmfull compared to DC which stays constant. Pranam
HBM has different standards (targets) for an IC and is typically 2000V to 4000V simulating the charge that a human body can accumulate and then discharge into an IC by touching one of the pins. Modern IC assembly does not use humans in contact with the ICs but the HBM is still a major (...)
To make an such characterization is very complex if the result should repeatable. A normal body varies a lot in size, shape due to movement, woman child or man, what types of clothes and environment. I know one company where one of the employee is their standard for anechoic chamber measurements were a full body is required. (...)

hi everyone, just wanna know more about how thermistor and ld35 work. which one is more suitable for human temperature measurement? and how do i measure if im using thermistor and the way ld35 measure the temperature. by skin contact to human body? or how? and (...)
but in case the antenna is near other lossy objects like human body, the power radiated would be decreased due to losses (due to power absorbed by human body), but S11 should remain the same. Is this correct? Please confirm. S11 will change when the antenna is near other objects. Some (all?) cell phones have buil

An expert system either supports or automates decision making in an area of which experts perform better than non experts. It is also known as "Expert Computing Systems", or "Knowledge Based Systems". [/Q
I want to calculate the induced electric field (and current) in a human body subjected to extremely low frequency (50~60Hz) magnetic fields form high voltage (500 or 220 KV) transmission towers. I've managed to determine the values of magnetic flux density throughout the human body height (...)
To detect a human body, the PIR suits well. But for determining the location?...May be one or more may be used...I guess...This system is implimented in a popular brand of Airconditioners which effectively cools in the direction it finds a human body...But never studied how this is done.
Hi, I'm doing a project for acquiring ECG signals. I've done probe with Ag, which is interact with human body(chest and leg). I need a good cable to connect the probe to the Amplifier with a low noise reduction. Please somebody give me the good choice! Thanks in Advanced! Added after 4 minutes: Is it
Hi, Anyone has information about calculating Specific Absorption Rate (SAR) by using Finite-Difference Time-Domain for a specific part of the body (for example head)? I have some papers about this topic, but want to know how should i start? This is what i understood from the papers: First i should have a human body model (...)
You posted this question twice, which means you are very scared. Was discovered that vhf stations could affect the length of human life, and you’ll never be able to reach 120 years old.
hi Friends, I am doing a research by which i will deduce the effect of the electromagnetic waves of the GSM900 and 1800 on the human body. my problem is i am using a spectrum analyzer but i am not sure if it is correctly give the results of the measurements. i hope if there are some engineers worked with this spectrum analyzer to (...)

For sure the human body will absorb allmost all IR radiation but this kind of circuit has been widely used. However, red leds seem to be less absorbed. To make a test place a red led behind your ear lobe and you´ll see it clearly (obviously you can´t compare it with an IR). The key is to use a very high intensity light emitter. In a (...)
Hi to all, can someone helps me to fine out the impedance model or the impedance equivalant circuit and the electrical characteristiques of a human body skin? Thanks in advance, alino
For my final dissertation at biotechnologiy faculty I have to study - among other things - a monopole with ground. As an absolute beginner with CST, I succeeded in designing the monpole thanks to your help and the tutorials. Now the problem is that I have to simulate the interaction of the ground monopole with the human body (a muscle) (...)
hi good day to all, im interested about the study on biometric identfication in matlab. through my own research, im interested in a fused project of two modes of a human body that is the iris and voice. the challenge is, i dont know how to fused the two system in matlab and because the two modes are largely different.

well SAR is a comrehensive topic so you need to do some searhing on it but as far as your question is concerned there is world wide regulation on SAR level and every new mobile handset launched into the market has to meet SAR criteria now for 10g SAR should be less then 2 so regulatory authority will have no objection to it regarding ur S11
Actually, each semicon devices is tested with esd zapper up to 15KV. The human body model of ESD is 2KV. The really really actual reality is, no body cares about esd that much unless the instrument that he build is esd sensitive.
