The Revitive IX is an electrical stimulation device that triggers muscle contractions in the feet and legs using light electrical impulses. The specially developed Isorocker function promotes additional movement. Colour, form and tactile materials direct attention to the user interface at the centre of the panel and hint at the technology inside. Thanks to intuitive operation, the device is also well-suited to older people, with visual and acoustic feedback having been incorporated to facilitate use. The selected materials are very robust, so that they can withstand high daily stresses.
