Physiokey is a bioadaptive therapy-device. Its soft, slightly bent shape nicley adapts to the therapists hand and allows working with high pressure for a long time. The overall shape epitomizes the picture of an active muscle and delivers an analogy to the devices main usage – the muscle stimulation. The geometrical, clear elliptical user interfaces outline results from a simple planar cut through the main body and carries touch-display and home button. The different accent colour of the electrode heads highlights their interchangeability. Depending on the specific usage-scenario, several different attachements are available. Additional side-electrodes create a continuous ionic flow.
