Publication number: 20070114885Abstract: A multilayer composite includes at least two composites, each composite having a film and an electronically conductive layer. Several composites are laminated to provide an increased conversion between mechanical and electrical energies not only due to the multiplication of the effect of each layer, but also due to the fact that the multilayer structure itself renders the multilayer composite more rigid. In addition, the multilayer structure facilitates application of an electrical field over thinner portions of the structure, thereby requiring much less potential difference between electrodes.Type: ApplicationFiled: November 3, 2006Publication date: May 24, 2007Applicant: Danfoss A/SInventors: Mohamed Benslimane, Peter Gravesen

Publication number: 20060079824Abstract: This invention relates to an elastic bandage for supporting a body extremity such as a leg. Such bandages are used to overcome problems with fluid retention and swelling in the legs, occurring as a consequence of varicose veins, vascular incompetence, pregnancy, etc. It is a task of this invention to supply an active support for a body extremity such as a leg, which can be used by a person underneath the clothes and will not reduce the mobility of the patient. This task is solved in that an elastic bandage comprises an elastic layer for surrounding a body extremity to exert compressive force on the extremity, the bandage being, at least partly, formed by elastomeric actuation elements, whereby electrical control of the compressive force is possible, and where the control is due to a signal from some sensing system.Type: ApplicationFiled: February 24, 2004Publication date: April 13, 2006Applicant: Danfoss A/SInventors: Jakob Munch-Fals, Mohamed Benslimane, Peter Gravesen, Theiss Stenstroem
