Summary
An in vivo
RFID chip implanted in a patient’s body, comprising an integrated antenna
formed on the chip, and a CMOS-compatible circuitry adapted for biosensing and
sending information out of the patient’s body. The RFID chip use a “rectenna”
with a rectifier circuit and supplies power to the chip by converting AC power
into DC voltage. RFID have a “local heater” sending current to different
biological function (affecting muscles, hormone and so on). CMOS sensors
adapted to to sense a chemical and/or physical quantity from a local
environment in the patient’s body. And a small nano carbon nano tube radio

Abstract
I will refer to two types of RFID (Radio frequenzy
identification) chip that I have source information. The first one is RAMBO
Microchip, and the other one is In vivo RFID. Both working in similar ways. I
will describe In vivo RFID. An in vivo RFID chip implanted in a patient’s body,
comprising an integrated antenna formed on the chip, and a CMOS-compatible
circuritry (CMOS MEMS sensor (Complementary
metal–oxide–semiconductor
Micro-Electro-Mechanical Systems sensor)) adapted for biosensing and transmitting
information out of the patients’s body. In preferred embodiments, the Complementary
metal–oxide–semiconductor) CMOS-compatible circuitry is adapted
to sense a chemical and/or physical quantity from a local environment in the
patient’s body and to control drug release from the drug reservoirs. Also, on a
RFID parts can be Local heater or a therapeutic application. And, parts like
radio
Radio frequenzy
identification (RFID)
In general,
these biomedically-relevant physical quantities are sensed and turned into a
measurable optical or electronic signals. RFID could be current implantable
biosensor, also a wireless, “no battery was needed” and small sized system. In
vivo RFID consist a(Hitachi µ-chip (RFID
tag)) Hitachi µ-chip.
Energy source: “Rectenna”.
Rectenna consist of a antenna, a
diode connected to ground and a low pass filter.
Referring
to FIG. 6, the OCA 52 can be integrated with a rectifier circuit (e.g.,
using a diode 62) to covert the AC power received by the OCA 52 into a DC
voltage. The chip 50 also include a CMOS-compatible RFID circuitry 54. The
circuitry 54 can be designed for storing and processing information,
modulation, and other specialized functions. By combing the CMOS-compatible
RFID circuitry 54 with the OCA 52, an integrated system is archived.
The
antenna can be made of out of a metal trace that is fabriced under CMOS standard and/or
CMOS-compatible metal processes. In one embodiment, the embodiment, the area of
the antenna can be scaled down to 0.1x0.1 mm2, and the number of
loops can be increased to compensate for the decrease size.
The local heater and
therapeutic application (RF nano-heathers) to affect biological system
Both, the
local heater and therapeutic application approach to the absorption of RF
power.
An approach
to the absorption of RF power is to use it as a local heater, which can be used
to effect biochemistry at the nanoscale for nanotechnology investigations and
potential therapeutic applications. This is another form of “RF remote control”
of biological function, which uses heat rather than circuitry to control
chemistry. Two examples using various forms of RF nano-heaters include:
therapeutic heathers and RF remote control.
The chip
can also be used to control the release of drugs(like hormones as adrenaline,
testosterone and seretonine), or to stimulate electrically biological function
for either therapeutic or diagnostic purpose. Drug reservoirs can be integrated
onto the RFID chip, allowing for intelligent or externally-controlled release
of drugs.
An
exemplary application would be the use of glucose sensors for diabetes
monitoring. Glucose sensors can be implemented in a patient to monitor blood
sugar levels, and then control the release of insulin from an on-chip
reservoir. This application allows the monitoring of blood sugar to occur on a
more frequent (or even continuous) basis than the conventional method of
testing that involves pricking the patient’s finger and putting a drop of blood
on a test strip once a day.
A
proportional-integral-derivative (“PID”) controller can be used to calculate
the difference between the measured process variable and a desired setpoint and
to adjust the process control inputs accordingly. Other algorithms that
integrate biological information for the optimum health tailored to the
individual patient may also be used. In general, there is a myriad of possible
biological events to b monitored in vivo, using emerging sensing technologies.
A single RF platform to interface to these new sensing and nanotechnologies in
the life sciences and biomedical device field.
Radio frequenzy
identification (RFID)
In general,
these biomedically-relevant physical quantities are sensed and turned into a
measurable optical or electronic signals. RFID could be current implantable
biosensor, also a wireless, “no battery was needed” and small sized system. In
vivo RFID consist a(Hitachi µ-chip (RFID

RFID Antennas
Research
regarding on-chip antennas ((OCA) RF antennas on the same chip as the
signal-processing components (using GHz near field antenna or MHz inductively
coupled coils). In the Guo reference, the researchers used an OCA operating at
2.45GHz. The on-chip circuitry used the energy from the incoming RF field to
power itself, so that no battery was needed. Fabricated with an eye toward the antenna
efficiency (i.e., a “good” antenna according to textbook antenna metrics would
broadcast efficiently over long range(internal antenna on chip)).
OCA and CMOS MEMS sensors
No battery was needed because OCA
use energy from the incoming RF field to power itself
CMOS sensors can be used to control
the release of drugs, or to stimulate electrically biological function for
either therapeutic or diagnostic purposes. The chip can be small enough that
control at the single cell level is possible.
Nano antennas on RFID chip
FIG. 7.
According to this embodiment, nanotube antennas and frequency domain
multiplexing are used for high band width communication with integrated
nanosystems, which comprises nanowires and nanotubes. Referring to FIG. 7. Long
nanotubes of different lengths, each a different frequency, are coupled to the
integrated nanosystem. He CMOS-compatible RFID chip 70 has multiple
nanostructure-based antennas 76, such as nanotube antennas, that together form antenna
arrays 71 extending from each of the four sides of the chip 70. Preferably,
each nanotube antenna 76 within the arrays 71 has a separate resonant frequency
and is configured to communicate over a separate wireless frequency. In this
manner, a multichannel communication signal transmitted from a nother device or
outside system 77 can be received on the chip 70. Because each nanotube 76
within the arrays 71 receives information on a separate channel, each of array
71 receives information on a separate channel , each of array 71 can act as a
communications port where each antenna 76 effectively acts as an input/output
connections.
The RFID
chip 70 can have any number of nanotube antennas 76 configured to receive,
transmit or both. In embodiments where each nanotube antenna 76 is tuned to
a separate resonant frequency, the number of a nanotube antennas 76 available
to receive data on separate channels is limited only by available bandwith. The
internal structure 72 of the chip 70 can range from simple nanotubes or
nanoelectrodes to more complex integrated nanosystem having nanotubes,
nanowires, nanotransistors, self-assembling DNA and the like
Small radio
Small radios and Radio
system
A small
nano carbon nano tube radio 20. This comprises an AM demodulator 22 made of a single carbon nanotube (
a molecular tube with radius of order 1 nm). Howerer, the external antenna 24
is serval cm in length, and the audio amplifer, speaker, and power supply
(battery) are of the shelf, so the entire system volume is of order 10-3m3.
Table 1
estimates the size of a possible single chip radio using “COTS” (commercial off
shelf) technology, as well as possible advances using nanotechnology. In
Fig. 3, the system size and single cell size of various existing and possible
radio systems are shown.
According
to a preferred embodiment, a unified single-chip universal platform 50 is shown
schematically in FIG. 5. Referring to FIG. 5, the on-chip antenna (“OCA”) 52
can be designed and fabricated as an inductive coil with multiple loops on the
chip (the loops are shown in aggregate). The antenna can be made of out of a
metal trace that is fabriced under CMOS standard and/or CMOS-compatible metal
processes. In one embodyiment, the embodiment, the area of the antenna can
be scaled down to 0.1x0.1 mm2, and the number of loops can be
increased to compensate for the decrease size. Other embodiments of OCAs are
also possible, including but limited to spiral, linear, zigzag, meander, and
loop antennas.
