What is electric potential technology? A plain English guide

How DENBA’s electric potential field works, what the research measured, and what it is not. A straight answer to the most common question we get.
Electric potential technology has been used in Japan for decades. DENBA is a modern, patented take on the idea, and the most common question we hear is simple: what does it actually do?
The short version
The device plugs into the wall and creates a 360 degree electric potential field that extends 1 to 1.5 metres in every direction. It runs at 50 to 60Hz, the same frequency as your household power, with an output current of just 0.02A. You do not touch it and you do not feel it.
Why water matters
Around 60 percent of the human body is water. DENBA’s field is designed to cause water molecules to microvibrate. The theory, explored in studies at universities in Japan, is that this supports circulation and cellular activity while you rest.
What the research measured
- University of Tokyo (Ethics Review No. 21‑176): enhanced sympathetic and parasympathetic activity after 15 minutes in the field.
- Professor Fumiharu Togo: increased delta wave power shortly after sleep onset.
- Further studies at Keio, Tsukuba, Teikyo, Azabu and Suwa University of Science.
What it is not
DENBA is a wellness device. It is not a medical treatment and it is not a substitute for advice from your doctor. If you have a pacemaker or other implanted electronic device, speak with your doctor before use.
Safety and certification
Every unit carries PSE (Japan), CE (Europe), FCC (USA) and RoHS certification, and the technology is patented in 49 countries including Australia.
