MEDICAL ELECTRONICS
BIO-AMPLIFIERS
ISOLATION
ADVANTAGES
Withstand high voltage. It protect the patients and the circuit
Amplify signal while passing only leakage current to prevent shock
CAPACITIVE ISOLATION
ADVANTAGES
No modulator or demodulator is needed
High linearity
Original frequency and amplitude is needed
TRANSFORMER ISOLATION
ADVANTAGES
High accuracy, Linearity and CMRR
OPTICAL ISOLATION
ADVANTAGES
No modulator or demodulator is needed
High linearity
DIFFERENTIAL
OPERATIONAL
INSTRUMENTATION
ADVANTAGES
High gain
Good CMRR
High input impedance
CHOPPER AMPLIFIER
MECHANICAL
NON-MECHANICAL
DIFFERENTIAL
ADVANTAGES
Stable gain

MICRO
ELECTRODES
METALLIC
NON-METALLIC
measures electric potential within a cell
BODY SURFACE ELECTRODES
ADHESIVE TYPE ELECTRODE
SUCTION CUP ELECTRODE
METAL PLATE ELECTRODE
EAR CLIP AND SCALP ELECTRODE
FLOATING ELECTRODE
It avoids measurement errors
