The needle tip of the microneedle 92 is lower than the opening surface of the can body 91, and the distance H ₂ from the opening surface of the can body 91 is 1.50 ± 0.25 mm.

In use, the microneedle 92 in the microneedle electrode 900 contacts the skin to detect the body impedance at the relevant acupoint. The microneedle electrode 900 of the present embodiment can only pierce the palm epidermis when the user's palm presses. It will not puncture the cortex and bleed, and the user will not have obvious pain. When the microneedle 92 contacts the palm of the user, in order to enhance the reliability of the contact between the microneedle 92 and the palm, the can body 91 is also filled with a cotton ball infiltrated with physiological saline or medical alcohol, and the physiological saline water contains 0.9%, and the cotton ball simultaneously Can achieve disinfection.
