Collecting Information regarding implantable devices and how to deactivate them without operation

An example of how cochlear implants show up in an x-ray - the connecting coils are clearly visible, the circles in the centre are small magnets that hold the external part in place on the skin. The box is the electronics unit and you can just see one of the small spiral electrodes in the ear, if you follow the wires down.

Any kind of electronic implant MUST have a battery built in to be able to operate on its own. With no battery, it is only powered when the external unit is located over it's coupling coil.

They do not use radio communications as that takes [relatively] massive amounts of power and the battery life would be reduced to days or even hours.

Any communications - and often power or battery charging - is done via a coupling coil placed over the device, working in conjunction with a coil in the device or linked to it, just under the skin.

If you look at x-rays showing people with cochlear implants, you can easily see the coupling coils that allow them to link to the external unit. That's state-of-the-art implant technology.

The external power or communications unit could have bluetooth or wifi etc., to pass data from the implant - I think?? some cardiac pacemaker systems work like that, so a doctor can do remote checkups with the users cooperation?


Note that all the stuff online about supposed injectable or implantable "tracking" or "controlling" implants is total fantasy, they are absolutely impossible by basic science and physics, for multiple reasons.


The nearest thing in reality is an RFID style device like a "Pet passport" tag, by no means invisible or undetectable and only working when a reader device is within a few inches to power it. They are the same basic technology as contactless keyfobs or cards for door entry systems etc.

Are such cochlear implants safe? Does anyone have first-hand experience here?

We all know that there are microchips that can be implanted inside a human body where they can measure temperature, blood pressure, glucose levels, etc and provide real time results to your phone.

Assuming it is a Bluetooth chip, although it can be an RFID tag or any kind of an implant that is present in the market today.

1) what kind of technology the latest implants available in market today use to communicate? I know Bluetooth and RFID tags, Please tell all that can be bought. Assuming that the implanting person can buy almost 90% of the implants available in the market. Money and procuring them is not an issue.
2) Since the chip has to have an antenna to transmit the signals and it could be anything, but it has to be conductive in nature. What are the materials available in market for antenna part of the chip that are used in an implant?

3) We are assuming that the chip doesn't has a battery of its own but if it had one, what material would be used that can last the longest and with the present technology what can be their maximum life? And are there any batteries that can be charged through electrical biochemical reactions in the body?

3) Any kind of implant has to be put in a silicone casing before being implanted, since it's the choice in every kind of implant and is least reactive inside the body. So, I want to know if there is a way where we can fry the chips inside systems inside the silicon casing without harming the subject.

4) Since these implants carry critical personal information, how can they be destroyed if a surgical procedure is not possible?

Of course they are safe, there are huge numbers in use all over the world - and certainly for Victoria it revolutionised her life - while my wife knew her from school, I knew her from teaching her Ju Jitsu (with particular care not to damage the implants).

I am sceptic about the safety issues of those devices.

It should be possible to destroy RFID implants safely by subjecting them to a strong field, with a frequency matching the implant's operating (i.e. resonant) frequency. This doesn't guarantee the information is destroyed, but it would be rendered unreadable, without first removing it from the body.

I would be very concerned that such a strong field would cause severe heating of the implant's electronics, possibly sparking. I guess you could test it out on some sample devices and see if they get too hot or the casing is compromised.

If they are ever approved for use beyond experimental, I'd then consider the surgery needed far more of a risk than the device itself.
Having a chunk of skull temporarily removed to install such a thing is taking things a bit too far for me!

I find the speculation of power supply almost laughable.

well over 20 years ago, i powered a clock circuit using captured energy of an AM radio broadcaster... since power consumption has vastly improved in the three decades, I'm 99.99% sure an app could be made to run within a human's body.
the only problem being, it had to be a powerful broadcast and tuned to closest AM station. and even a "super station" couldn't work beyond a limit. while the immediate strength definitely would power it, power dissipates as it go father so a super station's signal will fail long before the actual broadcast peters out.

1: Receivable power is proportional to among other things, RF field strength and antenna size.
The supposed microscopic and undetectable implants that the conspiracy theorists rant about would be far too small to collect enough energy to do anything, never mind actually communicate.

An RF field strong enough to power them would cook everything in the area first.

2: The supposed implants are surrounded by 80% water containing electrolytes, that is quite conductive and will both absorb RF energy and mess up resonances in any antenna contained in it without significant clearance.

3: A well designed LCD clock or watch takes a minuscule amount of power - but its not running radio circuits to communicate externally over long distances, as the supposed implants do!

No.
The receive voltage levels of radio signals that could be picked up by an antenna in an implant within a human body are simply orders of magnitude too low to do anything at all.

As an example, you mention cell phone signals.
Those are active, powered devices with very low noise and high gain amplification. They can work with signals down to around a millionth of a volt, as they are active devices.
