A bio-impedance measurement apparatus includes a flexible band member fastened around a body portion, two probe sets attached to the flexible band member, a measurement device, and a wireless device. One probe set includes a probe having a tip portion for piercing the skin of the body portion to be located adjacent to an acupuncture point. Another probe set, used as an electrical ground, includes a probe that contacts the reference skin. The measurement device is disposed on the flexible band member and electrically coupled to the two probe sets to provide an impulse current signal to the acupuncture point. The measurement device amplifies and measures the voltage response across the acupuncture points and the ground. The amplified signal is converted to a digital signal for Fourier transformation. The wireless device, coupled to the measurement device, transmits the acupuncture code and impedance information to a remote monitor station.
