Biophysical innovation
Advanced frequency algorithms support the body's own processes at the cellular level — gently, naturally and without any technical device.
Natural companions in everyday life
e.CHI frequency chips are applied to the affected area like a patch. From there they activate the body's bioelectrical field — no battery, no device, and active for up to nine months.
No side effects
e.CHI frequency chips are made of skin-friendly silicone and contain no chemical agents whatsoever.
Scientifically researched
e.CHI frequency technology builds on more than 30 years of biophysical research and is continuously tested in cell-biological studies.

See all questionsFrequently asked questions, briefly explained.
Every body responds in its own time. Some users report a difference within days, for others it takes a few weeks of continuous wear. We recommend wearing the chip consistently for at least four weeks before judging its effect.
The chip is designed for continuous wear, day and night. It remains active for up to nine months from first use.
No. The chip is designed to stay on around the clock — many users find night-time, when the body regenerates, especially valuable.
Place the chip on or as close as possible to the affected area — for example on the knee for the Knee Osteoarthritis chip, or on the lower back for BackFriend. Each product page shows the recommended position.
Direct skin contact works best, but the chip can also be worn very close to the body — for example fixed inside a knee sleeve or waistband — without losing its function.
The chip itself is made of skin-friendly silicone. If the adhesive plaster irritates your skin, you can fix the chip with a hypoallergenic tape or wear it in a sleeve close to the body.
Each chip stays active for up to nine months from first use. After that, simply replace it with a new one.
Yes. The chip is water-resistant and made for everyday life — showering, swimming, sweating and sport are no problem. Replace the plaster if it loosens.
As a precaution, we recommend consulting your doctor before use by children or during pregnancy.
Yes. Do not use e.CHI chips if you have epilepsy, severe heart failure, an organ transplant or a severe mental illness. If you are unsure, please speak to your doctor first.
