2. Biosensor
• Defined as sensors that allow the measurement and
interretation of the biological response of activated sludge
to a known disturbance ,which converters a biological
response into an electrical signal ( detets , records and
transmit information )

3. principle of opertion
• Capacitive sensing based on
capacitive coupling can be utilized
for cell studies with the use of
CMOS sensors.
• The capacitance sensor uses the
principle of charge sharing and
translates sensed capacitance
values to output voltages
• As a result, the measured
capacitance depends on a variety
of factors related to the cell, growth
medium, and supporting substrate

4. To imrove sensitivity make sensor array
The device could be used as an immunosensor,
with its sensitivity being enhanced by gold NPs.
