People's emotional stress not only makes the human heart beat fast, and people's skin become wet. Because the skin becomes wet, its resistance becomes low, so that the test device reacts. Test bars and soft wires are wrapped around the fingers or wrist as a receiver, the output signal is amplified by IC1 and read out by μA meter and R3. μA middle indicates 0, then C1 suppresses hum. During the period of time, the skin resistance can determine people's general emotional state, which is indicated by the table connected to the E. IC2 forms the integrator to ensure that the circuit automatically adjusts the average skin resistance.
