7. CONTROL CHIP
* The major component in a Control
Chip is ASIC.
* The ASIC (Application Specific
Integrated Circuit) is connects
togethere with other components of
the micro system.
* ASIC & sensors consume 5.5 mW
power corresponding to 1.7 mA of

8. BIOCOMPATIBLE CAPSULE ENCASING
MICROSENSOR
* The Silicon Diode is used for measures the
body temperature.
* The ISFET is used for measure pH of our
body.
* The Direct Contact Gold Electrode is used
for measures the Conductivity, by measuring
the contents of Water & Salt absorption.
* The Three Electrode Electro Chemical Cell

9. RADIO TRANSMITTER
* Modulation Scheme = Frequency
Shift Keying (FSK)
* Data Transfer Rate = 1 kbps
* Frequency = 40.01 MHz at 20°C
* Bandwidth of the signal generated 10
KHz
* It consumes 6.8 mW power at 2.2 mA
of current.

10. BATTERY
* 2 Silver Oxide batteries are used.
* Operating Time > 40 hours.
* Power Consumption = 12.1 mW
* Corresponding current consumption =
3.9mA
* Supply Voltage = 3.1 V

11. ADVANTAGES
* It is being beneficially used for disease
detection in human body.
* Power consumption is very less.
* It has very small size, hence it is very easy for
practical usage.
* High sensitivity, Good reliability & Life times.
* Very long life of the cells(40 hours), Less Power,
Current & Voltage requirement (12.1 mW, 3.9
mA, 9.1 V)

12. DISADVANTAGES
* It cannot perform ultrasound &
impedance tomography.
* Cannot detect radiation
abnormalities
* Cannot perform radiation treatment
associated with cancer & chronic
inflammation.
* Micro Electronic Pills are expensive

13. APPLICATIONS
* Determine Body Temperature.
* Determine pH value of our Blood.
* Measure Dissolved Oxygen level.
* Determine Pancreatic Disease.
* Measure value of Acid excretion.
* Determine activity of Fermenting
Bacteria.
