Dec 2005: R&D Begins, Distributor Hired

Bill Gates wants his mouse back! Created by Dr. Tennant in 2005, using a Microsoft mouse as the form-factor starting point, the Tennant BioModulator R&D begins. See his original drawing above, provided to Avazzia (a contract manufacturer) by Dr. Tennant.

Dr. Tennant, who founded Senergy Wellness Group back in 1996, 8 years later hires his step-son Scott Tennant to distribute the planned BioTransducers® and BioModulators®.

2006: Manufacturer Engaged, Prototypes Developed

Since microcurrent devices are regulated by the FDA, Dr. Tennant engaged Avazzia to manufacture the BioModulator and to do the FDA clearance + paperwork. See an example of engineering meeting notes above.

Without Dr. Tennant's knowledge, Avazzia applies for and is granted a patent for the BioModulator.

Oct 2006: Trademark Issued

Dr. Tennant is issued the Tennant BioModulator® trademark from the US PTO. It is still active and enforced today.

2005: Tennant BioModulator® Plus

This version of the Tennant BioModulator was targeted at individuals wanting basic pain remediation. NOTE: Senergy Wellness continues to sell these outdated devices without Dr. Tennant's permission.

Very effective for its time, but no real updates since 2005. 
Sept 15, 2008: Dr. Tennant transfers ownership of Senergy to Scott Tennant.

2012: Tennant BioModulator® Pro

Dr. Tennant's Pro targeted health care professionals treating patients, and included his branded Ten-8 and Infinity modes.

Effective for its time, but assess mode not as effective as hoped. Frequencies not updated for at least a decade! NOTE: Senergy Wellness continues to sell these outdated devices without Dr. Tennant's permission.

New! Tennant BioModulator Plus and Pro Devices

Now Shipping, the BioModulator® has been revamped, with 80% of the frequencies updated by Dr. Tennant. NOTE: these are Dr. Tennant's only authorized BioModulators. 

The PLUS makes it easy to follow Dr. Tennant's 2025 protocols, and the Pro adds 7 practioner-focused frequencies. This hardware is produced by Scenar in Russia; Scenar has been in the microcurrent device market for 40+ years, and their hardware has been approved by the FDA-equivalent bodies in 36 different countries! Their device has outsold Avazzia 10x. The new BioModulator hardware is routed through Israel; the firmware is updated with Dr. Tennant's proprietary frequencies, and makes its way to you.
