AMI Device

What is the AMI?

The AMI (Apparatus for Meridian Identification) works by monitoring the electrical conductivity and capacity at specific acupoints at the tip of fingers and toes (called Sei point, or Jing/Well points). After years of research, Dr. Motoyama was able to show that there is a close correlation between the electrical conductivity of meridians and the flow of Ki (or Chi) in the meridians. The basic research Dr. Motoyama did to support his claim about the AMI can be found in his book “Measurement of Ki Energy Diagnoses & Treatment: Treatment Principle of Oriental Medicine from an Electrophysiological Viewpoints” published by Human Science Press in 1977. Please see below (Dr. Motoyama’s Findings using the AMI) for the pages from this book.

What does the AMI measure?

The AMI measures the electrical conductivity, capacitance, and polarization of skin tissue and fluids; it uses these to evaluate the tissue condition and the functioning of the acupuncture meridians and their corresponding internal organs.

The AMI data tells you:

● The condition of the meridians and the functioning of their corresponding internal organs – lung, large intestine, heart, small intestine, spleen, liver, stomach, urinary bladder, kidney and gall bladder;
● Whether your Ki energy is excessive or deficient ;
● An objective analysis of your autonomic nervous system;
● The effects of acupuncture, meditation, and exercise through continuous monitoring of the autonomic nervous system and Ki energy;
● Chakra type, meaning which chakra is most active/inactive. The data cannot measure the amount of energy in the chakra quantitatively but can indicate which one is activated at the moment.

Dr. Motoyama’s Findings using the AMI

Extracts from “Measurements of Ki Energy, Diagnosis, & Treatments” (1997) by Hiroshi  Motoyama, Ph.D., Ph.D., Tokyo, Japan, Human Science Press

Substantiation of the Existence of Acupuncture Meridians

1)      Evidence of Meridians – Triple heater meridian

2)      Experiments with Liquid Crystal

Data Obtained Using the AMI

1)      Explanation of Measured Wave Form (BP, IQ, TC, AP)

2)      The BP Current mainly flows in the Dermis/Connective Tissue

3)      Where Does the Electrical Behavior of IQ, TC and AP take place in the Skin Structure?

BP is a Parameter Reflecting Meridian Function. Evidence suggests that the Dermal Connective Tissue is the Physical Location of the Acupuncture Meridian

1)      BP alone shows a Close Relationship with the Meridian Function

Structure and Function of the Dermis

1)      Components of the Dermis and their Structure

2)      Characteristics of the Dermal Connective Tissue which seems to determine the BP Values
(the dermal connective tissue as a reservoir for electrolytes)
(a close relationship between hyaluronic acid composition and BP value)

3)      Fundamental Physical Nature of the BP Current
