 Conclusion

3.  “Biochips”- exciting future technology for
Computer science, Electronics & Biology.
 It was developed in 1983 for monitoring fisheries.
 Now it is used over 300 Zoos & 80 government
agencies in 20 countries.
 Yearly, 6 million recipients of prosthetic devices
and breast implants are “biochipped”.
 Over 7 million animals have been biochipped
 Major biochip companies are A.V.I.D (American
Veterinary Identification Devices), Trovan
Identification Systems.

4.  Biochip implant is a small (micro) computer chip,
inserted under the skin, for identification
purposes.
 Biochips system is radio frequency identification
(RFID) system.
 RFID system uses low-frequency radio signals to
communicate between the biochip and reader.

5.  It’s a new type of bio-security device to accurately
track information .
 No need of remembering pesky PINs, Passwords
& social security numbers.
 No need to carry the medical records to hospital &
cash/credit cards.
 Biochips have the capability of locating lost
children, wounded soldiers

6.  Transponder in biochips is of passive type,
contains no battery of its own.
 Advantage of passive transponder is, it has very
long life up to 99 years and no maintenance.
 Transponder consists of four parts
i) Computer micro chip
ii) Antenna Coil
iii) Tuning capacitor
iv) Glass Capsule

7. Microchip :
•It stores identification numbers from 10 to 15
digits long
•The ID number is etched via laser on to the
microchip
Antenna coil:
•It’s a simple coil of copper wire around a iron
core which receives and sends the signal from
reader
Tuning capacitor:
•It stores the small electric charge sent by
reader or scanner and activates the
transponder.
Glass capsule:
•It houses the entire transponder ;usually of the
size of a uncooked grain of rice measuring
about 11 mm in length and 2 mm in diameter.
•It is made of soda lime glass.

8.  It consists of an “exciter” coil which creates an
EM field via radio signals.
 It provides necessary energy (< 1/1000 of a watt)
to excite the implanted biochip
 Reader also carries a receiving coil that receives
transmitted code from the implanted biochip
 This is all takes places very fast (milliseconds)
 Reader contains the software to decode the
received code and result in an LCD.

10.  With a biochip tracing of person/animal, anywhere in
the world is possible.
 A biochip can store and update financial, medical,
demographic data, basically everything about a person
 A biochip leads to a secured E-Commerce systems
 Biochips really are potent in replacing passports, cash,
medical record

11.  Biochip as Glucose Detector
 Proposed principle of Glucose detection
 Biochip as oxygen sensor
 Biochip as an Blood Pressure sensor

12.  A chip implant would contain a person’s
financial world, medical history, health care —
it would contain his electronic life“.
 "It is very dangerous because once kidnappers
get to know about these chips, they will kill
people to find them.

13.  The Biochip must retain data only if it is placed in a
fluid medium like blood & not in any other medium.
 Generic model of biochips consists of only ROM
component because passport number, Bank card
number normally permanent in nature.
 This technique is suitable for identification of dead
bodies (murdered by the kidnappers) as it loses the
data about the social security number
 But the induction of RAM component in addition to
ROM is a mere solution.

14.  A chip implanted somewhere in human bodies might
serve as a combination of credit card, passport, driver's
license, personal diary.
 A chip inserted into human bodies might also give us
extra mental power.
