The energy self-sufficient radiofrequency transmitter has at least one electromechanical transducer with a rectifier circuit connected downstream and with a voltage converter circuit. The PHI Cell system produces hydro peroxides, super oxide ions, ozonide ions, hydroxides and other oxidative gases. One of the arms is engagable along an engagement edge thereof with the reference surface. A striking unit is located in the body and located behind the cylinder to introduce air into the chambers via the inlets. The photosensitive elements are mounted on the common substrate with the possibility to be replaced without disturbances of the photosensitive surface flatness.
