DETECTION DEVICE

Abstract: a detection device includes an hbc (human body communication) module, a first coupler, a first adc (analog-to-digital converter), an electrode element, a second coupler, a second adc, a signal processor, and a tunable matching circuit. the hbc module generates an hbc signal. the first coupler generates a first branch signal according to the hbc signal. the first adc converts the first branch signal into a first digital signal. the electrode element receives a physiological signal from a human body portion. the second coupler generates a second branch signal according to the physiological signal. the second adc converts the second branch signal into a second digital signal. the signal processor generates a control signal according to the first digital signal and the second digital signal, thereby adjusting the impedance value of the tunable matching circuit.
