Have you heard about medical device implantation inside the human body?Devices implantation is done for many purposes, such as diagnostic, healingdamaged tissues, monitoring heart rate and more.
Have you ever wondered how the process of implementing a device in the human body is done? Naturally, such procedure requires immense precision. Perhaps you will be surprised,but doctors nowadays have access to technology which shows the position of foreign objects inside the human body, without physically seeing the object.
How are they able to do it?What kind of technology they are using?

Involvement of Micro Coil Winding Technology
The secret lies in micro coil winding technology. This technology helps a broad range in the medical fieldand can be also used as location sensor inside the human body.
The coilscan transmit electromagnetic waves between one another. Let’s assume that we have a,b and c coils in our body. When the electromagnetic wave passes through them a and c can easily find out where b is moving and vice versa. All coils can, in a sense, detect and trace each other in space.
Positioning as an Important Factor
Surely you understand how important precision and knowing the position when implementing an object inside the human body. Because doctors cannot physically see their positioninside the body, they mustrely on wireless electromagnetic induction produced by micro coil winding.
Size Factor Matters
The size of a micro-coil is 0.8 mm. Special knowhow and machinery is required in order to produce coils of such small measure. Only a few companies in the industry have the means to do that.
A micro coil can easily be placed within a vein. The material that is used for the electromagnetic micro coil is copper. The coil is designed in a way that each winding is isolated from its neighbors. The electromagnetic conduction is made possible thanks to a magnetic core which is inserted right in the middle.
Problems with the Electromagnetic Waves
The problem that the electromagnetic wavesfaces while passing through the human’s tissues inside the inner body is it tends to dissipate. That’s why sometimes it is difficult to connect all the coils wirelessly and the doctors might have a problem finding the correct positioning once they are already inside.
To overcome this,there is an involvement of antennas in the system. These antennas induct the electromagnetic wave so that it can easily pass through the cells of the human’s body. As a result, the signal doesn’t lose intensity and the doctors are able to get much more accurate readings.
