Patent number: 11384453Abstract: An improved electro hydrodynamic method is provided. The method comprises arranging (11) an electro hydrodynamic device inside an enclosure and distributing (12) positive and/or negative ions inside the enclosure during a charging period with a certain defined amount of power. The distribution of the positive and/or the negative ions inside the enclosure (20) is performed so that a predefined amount of charge is set on the interior of the enclosure (20). Within a predetermined period of time after the charging period has ended, the electrospinning device is activated so as to create a product. Finally, the product is removed from the device. The present invention offers a solution for the problem of non-identical initial process conditions for an electro hydrodynamic process caused by any electric charges on the equipment.Type: GrantFiled: October 19, 2018Date of Patent: July 12, 2022Assignee: Innovative Mechanical Engineering Technologies B.V.Inventors: Ramon Hubertus Mathijs Solberg, Marc Simonet, Paul Johannes Franciscus Maria Janssen

Publication number: 20220205155Abstract: Method and device for depositing a fiber material layer on a carrier, such as using an electrospinning process. The device includes a deposition unit positioned remote from the carrier during operation, and the deposition unit is arranged for forming the fiber material layer on the carrier in a continuous manner A carrier feed unit is provided for feeding the carrier in a transport direction with a predetermined speed, and the carrier includes a plurality of carrier plates. A cutting unit is present and arranged downstream from the deposition unit, the cutting unit being arranged to cut the deposited fiber material layer in between two adjacent ones of the plurality of carrier plates.Type: ApplicationFiled: April 30, 2020Publication date: June 30, 2022Applicant: Vivolta B.V.Inventors: Paul Johannes Franciscus Maria Janssen, Ramon Hubertus Mathijs Solberg

Patent number: 11072873Abstract: An electrospinning device is provided with a container for holding a liquid comprising a polymer melt or a polymer solution, and a nozzle arranged to outlet a stream of the liquid from the container. A collector collects electro spun material during electrospinning so as to form a fibrous structure. The device comprises an optical measurement system that measures a baseline distance between the collector and the optical measurement system for at least one location on a surface of the collector, and also measures a momentary distance between the optical measurement system and a momentary top layer of the fibrous structure during the electrospinning process. A processor calculates a momentary thickness of the fibrous structure. Once a required thickness is reached the electrospinning can be stopped.Type: GrantFiled: April 20, 2017Date of Patent: July 27, 2021Assignee: Innovative Mechanical Engineering Technologies B.VInventors: Paul Johannes Franciscus Maria Janssen, Ramon Hubertus Mathijs Solberg
