A new implantable radio chip intended for medical applications now has been announced – but can forced tracking of everyone with this type of technology be far behind? Would anyone believe that any manufacturer would pass up a chance to implant hundreds of millions of people, and limit implants a small minority of medical patients as design-in product for cardiac, insulin pumps, etc…? This new device is FAR more sophisticated than the well publicized “Digital Angel” chip, pictures of which usually show a grain-of-rice-size transparent capsule with a coil at one end and a chip at the other.

How big is this new chip? It comes in two forms – a bare chip (or in “die form” as it’s called in the electronics industry) and a 48 pin plastic package as shown below. The plastic version in the picture below is not to scale – this device is actually a fraction of the size of a postage stamp measuring just 7mm x 7mm. In inches that’s about 1/4″ square or about the size of a #2 pencil eraser. However, packed into that small size is a 402-405MHz transmitter for operation in the “implantable medical service band”, 2.4GHz receiver, Media Access Controller/processor, error detection and data recording capability for later transmission. It can also be connected to an external 2.5GHz transmitter for other purposes. Unlike the dirt-simple Digital Angel technology which has already been hacked and can only send back a simple serial number, this is a COMPLETE system-on-a-chip with numerous capabilities including Reed-Solomon encoding. This encoding method is intended for high noise level signals and provides a high level of data integrity. This encoding method is also used by the both Voyager spacecraft to send images to Earth even today from outside our solar system. Although this chip does require a few external electronic parts, each of these external components are about the size of a grain of sand.

Without the plastic package shown, the bare chip is about this size: [ ]

A powerful chip like this would undoubtedly be the choice for police state implants. Whether or not digital angel is upgraded to meet this challenge, what we see here is the next generation of implants that will be competing for government approval for mass implantation. And if it can receive medical band signals – why not a satellite signal to release a toxin? Just 20 years ago, you needed a 10ft. dish to receive radio and television from satellite. Now look at a GPS you can hold in your hand. And that’s already old technology.

Here is a recent technical product announcement from the company:

Radio Chip Gets Under The Skin

For medical applications that include implanted pacemakers, defibrillators, neural stimulators, drug pumps, and physiological monitors, the ZL70101 transceiver, an ultra low-power RF system-on-a-chip promises high data rates, low power consumption, and employs unique wake-up circuitry. The device uses the company’s MICS technology, which eliminates the need for accurately positioning an inductive wand over the implanted device. Data can be stored in the implanted medical device’s memory and wirelessly transmitted to a base station without patient intervention. The transceiver integrates a wake-up receiver that allows it to operate in sleep mode, consuming 250 nA of current. Communication is then initiated using a specially coded wake-up signal from the base station transmitter. In full operation, the ZL70101 typically consumes 5 mA of supply current. Available as implantable-grade, wire-bondable die or in a 48-pin QFN (quad flat no-lead) package, the chip is fully supported by a reference system and application-development kit.

POWER CONSUMPTION EXPLAINED

Note the actual current consumption during FULL operation is 5mA. That’s .005 Amps, or about 1/20 of the current of a flashlight bulb. A cordless phone draws several hundred times this current from the battery. This chip’s standby current of 250nA (nanoamps) = .000000250 Amps, or 250 BILLIONTHS of an amp. It can still record data for later transmission while sleeping at this extremely low power level according to the company’s data sheet.

This chip could easily be powered without batteries by using motion transducers, zero point devices or with electrochemical power sources – also implanted in your body when the chip is installed. So are you ready to roll up your sleeve to accept something like this one day?
