Outline of Final Research Achievements	A multi-channel, skin impedance measurement system is developed for evaluation of effect of low-level laser stimulation to acupuncture point. The system measures cole -cole plots of skin impedance to detect acupuncture points where the impedance is lower than other parts. It is shown that, by using an impedance measurement system based on 9-channel matrix electrodes, acupuncture points are electrically detected. Furthermore, effect of low-level laser radiation is quantitatively evaluated by using the system.
