How It Works
How the Tennant System Works Correct Polarity. Restore Voltage. Let Your Body Do the Rest.
Following Dr. Jerry Tennant’s method, two current Tennant devices work together as one system. The BioTransducer® corrects polarity with scalar field technology, and the BioModulator® restores voltage with bioadaptive microcurrent. Here is what each one does, what using them looks like and what ownership includes.
- Use at Home or in a Clinic
- BioTransducer® Works Through Clothing
- Significantly Shorter Sessions
The Short Version
Enough Charge, Pointed the Right Way.
Before the devices, the idea behind them. Watch the short overview, then select a topic for the plain-language version of Dr. Jerry Tennant’s framework.
Your Cells Run on ElectricityVideo overview
Cells run on charge, and repair takes more of it.
Dr. Tennant teaches that every cell runs on electrical charge, measured as voltage. A healthy cell runs at about −20 to −25 millivolts. Making the new cells that repair tissue takes about −50. When voltage runs low, the body keeps going, but it cannot rebuild.
- −20 to −25 mVTo run
- About −50 mVTo make new cells
Charge has a direction, and it can flip.
Healthy tissue carries a negative charge. When tissue stays drained long enough, Dr. Tennant teaches, its polarity can reverse from negative to positive. Adding more energy does little until the direction is corrected, which is why the Tennant System addresses polarity and voltage together.
- NegativeNormal polarity
- PositiveReversed polarity
Six drains spend charge faster than you replace it.
Dr. Tennant groups the most common drains into six areas: stress, dental problems, emotions, toxins, thyroid function and scars. Addressing them is part of his method, alongside the devices, so the charge you restore has a chance to hold.
Explore the Six Drains→Where the Devices Fit
The BioTransducer® corrects the direction. The BioModulator® restores the amount. Together, they give the body what it needs to do the repair it already knows how to do.
Voltage, polarity and the six drains are part of Dr. Tennant’s educational framework. Tennant devices are not intended to diagnose, treat, cure or prevent any disease.
The Two Devices
One Corrects Polarity. One Restores Voltage.
The current Tennant BioTransducer® and BioModulator® each have a distinct job, and each runs on its own power. Select a device to see what it does and how it is used, or see how they work together.

Tennant BioTransducer®
Corrects polarity, without touching the skin.
The BioTransducer® uses scalar field technology to emit scalar energy, which Dr. Tennant teaches returns reversed polarity to normal so tissue can hold a charge again. You simply point it toward the area. It works through clothing.
- Contact-free. Nothing attached to the skin, and it works through clothing.
- Point and use. Direct it toward the area being addressed.
- Fully standalone. Its own rechargeable power, with nothing to connect.
- Portable. A protective case for home, clinic or travel.
General wellness device.

Tennant BioModulator®
Restores voltage, and adapts as your body responds.
The BioModulator® delivers bioadaptive microcurrent through skin contact. It reads how the tissue responds and adjusts in real time, which Dr. Tennant uses to help restore voltage where it has run low.
- Bioadaptive. Output adjusts in real time to the body’s response.
- Applied directly. Placed on the skin, with no footplates or hand grips.
- Shorter sessions. Session times have dropped significantly with current technology.
- SCENAR-based. Built on SCENAR technology, paired with Dr. Tennant’s protocols.
Intended for the relief and management of acute and chronic pain. Requires a licensed provider’s authorization, and Tennant Health handles that process for you. Not for use with implanted electronic devices.

The Tennant System
Polarity and voltage, in the same session.
Because each device runs on its own power, they can be used at the same time. Dr. Tennant’s method always corrects polarity and restores voltage, and running both together fits the whole approach into one shorter session.
- Same time. Polarity and voltage support run together.
- Nothing to connect. Two standalone devices, one system.
- One set of protocols. Official owner education covers both devices.
- Home or clinic. Built for everyday use wherever you are.
Tennant Health supports only the current BioTransducer® and BioModulator®, and Dr. Tennant’s protocols are built for them. Framework descriptions reflect Dr. Tennant’s educational model.
Using the System
Simple to Use. Built on Dr. Tennant’s Protocols.
No complicated setup and nothing to connect. Here is what a session looks like in plain terms, from getting ready to the time between sessions. Owner education covers the details.
Before a Session
Nothing to set up. Just power up and choose.
The BioTransducer® is rechargeable and the BioModulator® runs on AAA batteries, so there are no cables, footplates or hand grips to connect. Owner education shows you which areas to focus on and which of Dr. Tennant’s protocols fits what you are addressing.
- Ready to go. Keep the BioTransducer® charged and AAA batteries on hand for the BioModulator®.
- Know the area. Owner education shows how to choose where to focus.
- Follow the protocol. Dr. Tennant’s protocols are built for the current devices.
- Get comfortable. Sit or lie down, at home or in a clinic.
During a Session
Both devices, in the same session.
Point the BioTransducer® toward the area, even through clothing, to correct polarity. Place the BioModulator® on the skin to help restore voltage. They can run at the same time, and the BioModulator® adjusts to your body’s response as it goes.
- Contact-free polarity. The BioTransducer® never touches the skin.
- Adaptive voltage support. The BioModulator® responds in real time.
- One sitting. Polarity and voltage are addressed together.
- Shorter sessions. Session times are significantly shorter with current technology.
After a Session
Then let your body do the rest.
Dr. Tennant teaches that once polarity is corrected and voltage is restored, cells have what they need to do their own repair work. Your part is simple: stay consistent and pay attention to how you feel.
- Recharge. Put the BioTransducer® back on charge for next time.
- Stay consistent. Owner education covers how often to use the system.
- Notice changes. Keep track of how you feel between sessions.
- Ask anytime. Our team is here for ongoing owner support.
Placement, timing and protocols are taught step by step in owner education, which is part of the Tennant System.
