Summary
This study introduces microwave energy measurement to assess acupuncture point and meridian function, offering a non-contact alternative to electrical methods. Findings suggest distinct microwave propagation patterns in diabetic and cancer patients compared to healthy individuals.
Area of Science:
- Biophysics
- Traditional Chinese Medicine
- Medical Diagnostics
Background:
- Traditional acupuncture point and meridian functional assessments rely on electrical measurements, which are sensitive to environmental factors and contact variability.
- A novel, non-contact method using microwave energy is explored to overcome limitations of existing techniques.
Purpose of the Study:
- To investigate the feasibility of using microwave energy transmission to quantitatively assess the functional state of acupuncture points and meridians.
- To compare microwave energy propagation patterns in diabetic and cancer patients with healthy individuals.
Main Methods:
- Microwave energy (250-550 MHz) was irradiated on acupuncture points, and transmitted energy was measured at subsequent points along the same meridian.
- Measurements were conducted on all 12 meridians across both hands and feet in 50 healthy individuals, 50 diabetic patients, and 50 breast cancer patients.
Main Results:
- Diabetic patients showed significantly lower microwave energy propagation along the Lung channel (1.417 dB) and higher along the Spleen channel (1.601 dB) compared to controls.
- Cancer patients exhibited lower propagation along the Liver channel (1.620 dB) and higher along the Kidney channel (1.245 dB) relative to the normal group.
Conclusions:
- Microwave energy transmission presents a promising, non-invasive method for quantitative assessment of acupuncture meridian function.
- Distinct microwave propagation signatures were observed in diabetic and cancer patients, suggesting potential diagnostic applications.

01:28Standing Waves in a Cavity
A household microwave and lasers are examples of standing electromagnetic waves in a cavity. When two conducting metal plates are placed parallel at the nodal planes, it creates a cavity where standing waves are formed. The cavity between the two planes is analogous to a stretched string held at the points x = 0 and x = L. Here, the distance 'L' between the two planes must be an integer multiple of half of the wavelength. The wavelengths that satisfy this condition are given by:
01:30Propagation Speed of Electromagnetic Waves
Electromagnetic waves are consistent with Ampere's law. Assuming there is no conduction current Ampere's law is given as:
01:23Propagation of Action Potentials
The propagation of an action potential refers to the process by which a nerve impulse, or "action potential," travels along a neuron.
Neurons (nerve cells) have a resting membrane potential, with a slightly negative charge inside compared to outside. This is maintained by ion channels, such as sodium (Na+) and potassium (K+) channels, which control the flow of ions. When a stimulus, like a touch or a signal from another neuron, triggers the neuron, sodium channels open, allowing sodium ions to...

01:24The Electromagnetic Spectrum
Electromagnetic waves are categorized according to their wavelengths and frequencies, giving the electromagnetic spectrum. These waves are classified as radio, infrared, ultraviolet, etc. Radio waves refer to electromagnetic radiation with wavelengths ranging from millimeters to kilometers. Radio waves are commonly used for audio communications (i.e., radios) and typically result from an alternating current in the wires of a broadcast antenna. They cover a broad wavelength range and are used...
