Biometrics
oBranch of Science that deals with
oMeasurement of
oPhysiological Variables & Parameters.
oE.g:
oThermistor Senses Body Temperature
oStrain Gauge Senses Blood Pressure

Biomedical Instruments- parameters
o Range:- Expected operating level of the instrument
o Should have minimum to maximum range
o Sensitivity:- Ability to measure small variations accurately.
o Should not be too high or too low.
o Linearity:- Output to be steady or linear with respect to input.
o Hysteresis:- (hysterein-to lag)
o Should be minimum
o Frequency Response:- Variation in sensitivity over a range of frequencies.
o Flat Response (equal response to all ranges)
o Accuracy:- True reading-Actual reading.
o Should be high

Biomedical Instruments- parameters
o Signal-to-Noise Ratio:- Proportion of data.
oshould be very high.
o Stability:-
o Isolation:-
o Simplicity:-

Man-instrument System
o Human being:
o Living Black Box
o With a vivid range of systems.
o Like
o Electrical
o Mechanical
o Acoustical
o Thermal
o Chemical
