Dogs and cats are already equipped with subcutaneous implants allowing their electronic identification. So why not us ? The variants of the coronavirus, responsible for Covid-19, continue to multiply, like the rumors, sometimes far-fetched, which raise real concerns such as that of the injection of a 5G chip in the vaccine . The latter deserves the lighting of an expert.
A few months ago, a rumor took hold of the: the against the would contain electronic chips allowing the tracking of vaccinated people to retrieve private data. So is it possible or not?
Ironically, this rumor arose almost 56 years to the day after Gordon Moore, one of the founders of Intel, enunciated an empirical law indicating a doubling of the number of transistors on a microchip every About 2 years. This law is still verified today with the elementary electronic components – the transistors – which today reach.
Hello @CHUdeToulouse, I had my first injection of the Covid vaccine this morning and thank you for it.
However, I still don’t get 5G. Is this a bug? Should I wait for the 2nd injection or just contact my operator? ????

The first oneswere made with vacuum ampoules containing filaments and grids called triodes. By heating and effect , weak electrical signals could be amplified. This is what allowed the first wireless transmissions of signals in at the beginning of the XXe century. Bulky, fragile, expensive and operating with high voltages, they will be replaced by so-called state-of-the-art technologies. with material crystals .
The semiconductor component performing the amplification function was developed in the 1950s and the trade name was chosen by the Bell laboratories at the origin of this invention: the. The first , that is to say, the possibility of making several transistors connected to each other directly in the semiconductor crystal was realized at the end of the 1960s.
On an industrial scale, the square circuits are made next to each other to facilitate their cutting before packaging. In 2021,has just announced a realization of (or about twenty placed next to each other …): solid state found in the solid state disks of computers today, the solid state disks (SSD).
So how many transistors could we burn onto a piece of square integrated circuit that would go through the hole in the syringe used for the vaccine? The circuit is square, the needle is circular with an internal diameter of 0.6 mm: we start with electronics and here is a geometry problem which would give a hard time to a college student.
The side of the square which can enter a circle, in the worst case, 0.6 mm in diameter is 0.424 mm. This makes it possible to produce 1.8 billion transistors (for a surface transistor of 100 nm x 100 nm); as much as inwhich equip the previous processors of a brand’s phones headed well known.
It is therefore possible to put in a syringe for injecting a vaccinewaterproof with calculation capabilities similar to those of current cell phones. It is also necessary that it communicates with the outside and that it is supplied electrically.
It’s all hanging by a thread
This is not just a big problem, because the injected chip has to communicate wirelessly with the outside of the human body. Antennas must therefore be made on the chip for wireless communication.
This time it’s thethat will have to be used to size the antennas. James Clerk Maxwell is a and Scottish mathematician of the XIXe century. We owe him in particular the demonstration that used in the wireless transmissions of our propagate in space in the form of a wave at the .
According to the, the ideal size of an antenna should be equal to the ratio between the speed of light and the frequency of (the ). Sub-multiples of this ideal size (½, ¼, 1/8 …) can also be used to limit the size to the detriment of detection. uses frequency bands around 3.5 GHz. By choosing a sub-multiple of ¼ to limit the size of the antenna, an antenna of 2.1 cm must therefore be made to allow the electronic chip to communicate wirelessly with the outside of the human body.
With such a dimension, the entire surface of the chip is not sufficient to produce the antenna, even in the form of a coil. This is also something that we all know on the condition of practicing a sports activity and therefore going to a well-known sports brand: each item purchased has a chip.. The only really visible part of the chip is the coil-shaped antenna.
Flea in the ear
Theand cats are precursors in , because the tattoo has been replaced by an implantation of a chip in . The device is about ten millimeters long to simply contain a unique number that can be read without contact. This number is read by bringing the reading system close to the animal’s ear.
And this is the case with all wireless data transmission technologies: the distance between the implanted chip and the reader is small, often limited to a few centimeters. First, it is aboutprecisely to avoid being able to remotely detect the data exchanged; second, because the power emitted by an antenna decreases with cubic distance. To increase the reading distance, it is necessary to increase the emitted power and therefore increase the drums.
How can we simply quantify so that we can answer our initial question? Between complicated units, complex mathematical equations and results very dependent on experimental conditions, the question seems simple and the scientific answer is not. To try nevertheless to give an element of answer on the dimensioning of a battery, one can be interested in that of the mobile telephones: the range of a telephone is of 1 km for a volume of battery of approximately 10 cm.3. Assuming that half the volume of the chip injected with the vaccine is occupied by the battery, the range of the chip would be 0.1 cm. Given the size of the battery, the chip must therefore be in contact with the reading system in order to be able to exchange information.
So possible or not to put a chip in a vaccine?
The processor of a 5G chip can be injected through the hole of the needle used to inject the vaccine. The range will be low and will require a reading system in contact with the skin.
By account, the antenna for the exchange of information is impossible to achieve today.
The frequencies used in wireless telephony transmissions have increased tenfold in twenty years. By extrapolating this law, it will therefore be necessary to wait 60 years for the frequency of wireless transmissions to allow the creation of antennas small enough to be able to inject a chip into a vaccine. By then, we will all have been vaccinated against Covid-19.
