About Rayonex

The Company Paul Schmidt Development and Network

Rayonex Biomedical GmbH, located in the tranquil Sauerlands in Germany, is the developer of a holistic health system based on bioresonance according to Paul Schmidt. Its philosophy is that we must treat the root cause rather than the symptoms of ill health. Optimal nutrition, a balanced self-regulation system, and the minimisation of harmful effects from pathogens, toxins and environmental stresses will lead to health restoration and maintenance.

Based on Schmidt’s finding that all organisms are influenced by frequencies or oscillations, Rayonex developed bioresonance devices that are classified as Type IIa Medical Devices under EU regulations.


The safety and effectiveness of the devices have been shown in a 2019 double-blind randomised controlled study on Cervical Spine Syndrome patients, who overwhelmingly reported improvements in their conditions. Today, Rayonex products are sold in more than 43 countries, with over 5,500 naturopaths, therapists and doctors applying bioresonance treatments in Germany alone.

The story began with Schmidt, who was a visionary in the field of alternative medicine. Best known for his cause-oriented approach to health, he applied his scientific mind and engineering expertise to revolutionising bioresonance as a healing modality.

Paul Schmidt

Born in Altenhundem in the Sauerlands, Schmidt was a self-made man with innovative ideas and great compassion. His prolific work and scientific creativity resulted in over 300 commercial patents in his lifetime. Due to his father’s early death, his childhood was marked by deprivation and the need to improvise. He had strong technical skills and a gifted sensitivity to the vibrational energy of matter. Following an education in engineering science, he became an engineer, developed agriculture machinery and founded his own tractor company. He started experimenting with frequencies in 1976, first with spectrometers and frequency generators, then eventually building his own bioresonance devices. He established Rayonex Biomedical GmbH in 1982 to focus on his ground-breaking concepts of alternative medicine.

While building his business, Schmidt maintained his lifelong commitment to social and cultural affairs, sketching children’s books for kindergartens and contributing in various ways to his community. He was awarded the Federal Cross of Merit of Germany (Bundesverdienstkreuz), a decoration which recognises the contribution of Germans and foreigners in the fields of political, socio-economic and intellectual activity.

"Under the stewardship of CEO Prof. Dietmar Heimes"

With nearly 4 decades of development since the founding of Rayonex Biomedical GmbH in 1982, the company has succeeded in presenting the most comprehensive health system in the world, with solutions ranging from bioresonance treatments to nutritional supplements and e-smog protection.

Under the stewardship of CEO Prof. Dietmar Heimes, Rayonex has grown from a company of 3 people in 1982 to boasting a dedicated staff of 58 on its expanded premises. From the rayometers of old, devices including the Rayocomp Polar for professional use and the PS10 for home use have been developed and periodically upgraded. These devices incorporate Paul Schmidt’s ingenious use of the dipole antenna system to produce decadal frequency spectra of a harmonious nature that require no electricity. They also incorporate a newer system of bioresonance testing and harmonisation called RAH (Rayonex Analysis and Harmonisation), which is the result of collaboration of more than 30 experts around the world. The system works for humans as well as horses, dogs and cats, and are highly appreciated by doctors, naturopaths and veterinarians.

Today, the Rayonex health system is used in more than 43 countries, with over 5,500 naturopaths, therapists and doctors applying Paul Schmidt’s bioresonance treatments in Germany alone. The biofield forming devices are so effective and popular that to date, there are more than 100,000 users of the Mini-Rayonex and 30,000 users of the Duplex around the world.

All Rayonex products are made under the strictest standards to guarantee the highest quality and safety, with Quality Management Certificates continuously being renewed.

The effectiveness of Rayonex bioresonance devices has been the subject of a number of studies, including the In vitro study of the effect of the Mini-Rayonex on cell metabolism by the Dartsch Scientific Institute, and the Efficacy Study by the Fraunhofer Institute, both of which show that frequency spectra from Rayonex bioresonance devices have a positive influence on cell metabolism.
