Terahertz and PEMF are not synonyms. Terahertz describes a high-frequency spectral region; PEMF describes a field delivered in pulses. When both terms appear on a foot-wellness product, an importer should separate the commercial category name from measurable output claims.
What “terahertz” means in science
Scientific literature commonly describes the terahertz region as approximately 0.1–10 THz, between microwave and infrared frequencies. Terahertz waves are non-ionising and interact strongly with water. Research applications include spectroscopy, imaging and sensing. Reviews also emphasise water absorption, penetration limits, variable exposure systems and the need for better standardisation before broad clinical conclusions.
A product name, mineral plate or illustration does not demonstrate terahertz output. A verified emission claim needs a suitable spectrometer or detector, a defined bandwidth, distance, operating mode and model-specific report.
What PEMF means
PEMF means pulsed electromagnetic field. It can be characterised by waveform, repetition frequency, magnetic flux density or other relevant output magnitude, pulse width and duty cycle. PEMF does not define one universal frequency or health effect.
Two technologies, two verification paths
| Buyer question | Terahertz claim | PEMF claim |
|---|---|---|
| What is being described? | A spectral frequency region. | A time-varying pulsed field. |
| Useful evidence | Spectrum, instrument, bandwidth, distance and test setup. | Waveform, frequency, magnitude, pulse width, duty cycle and geometry. |
| Does a name prove output? | No. | No. |
| Does output prove a health benefit? | No; clinical relevance needs separate evidence. | No; clinical relevance needs separate evidence. |
| Key importer task | Define the claim and measurement method. | Identify architecture and parameter definitions. |
Why 1 MHz is not 1 THz
One megahertz is 106 hertz; one terahertz is 1012 hertz. They differ by a factor of one million. If a catalogue lists a 1 MHz operating parameter, that value must be described in its own model context and must not be used as proof of emission in the terahertz band.
What the current literature supports
A review of terahertz biomedical applications discusses diagnostic and sensing research. Reviews of cellular effects and exposure systems and terahertz imaging describe promising research alongside measurement, water-absorption and reproducibility limitations. Therefore, responsible B2B content should say “studied” or “under investigation,” not claim proven detoxification, microcirculation repair or disease treatment.
A due-diligence workflow for distributors
- Define intended use: home wellness, spa demonstration or another lawful channel.
- Separate functions: foot contact, heat, PEMF/pulsed output, negative ions and any other module.
- Define every number: input voltage, mains frequency, output frequency, power, level and timer.
- Request measurement context: instrument, unit, distance, load and operating mode.
- Match documents: unit label, manual, carton and reports must show the ordered model.
- Localise responsibly: translate instructions without adding unapproved medical claims.
Youborui model positioning
The P92 160 W foot wellness device combines a foot-contact format with adjustable controls and a supplier-listed 1 MHz parameter. The P91 and P93 support different distributor positioning and enclosure formats. These products use direct plug-in power. Buyers should request the current voltage, plug, accessory list and model-specific documentation.
Frequently asked questions
Are terahertz and PEMF the same?
No. One is a spectral frequency term; the other describes pulsed-field operation.
Can a 1 MHz value be called terahertz?
No. 1 MHz and 1 THz are separated by six orders of magnitude.
What is the best proof of a technology claim?
A model-specific test using an appropriate instrument and a transparent method, followed by separate evidence for any claimed user outcome.

Request a model-specific OEM/wholesale quotation
Send Youborui your destination country, sales channel, expected quantity, required voltage and plug, private-label needs, packaging language and required documents. We will match the request to the current terahertz/PEMF foot-wellness configuration rather than quoting from a generic catalogue description.
