Patent number: 8928206Abstract: The invention relates to a method for obtaining electrical energy from the kinetic energy waves. According to said method, a device is provided in the water, comprising an electroactive polymer that can expand with the action of the waves. When the electroactive polymer expands, an electrical charge is applied at a specific time for a specific time interval. Said electrical charge is removed during the relaxation of the polymer, except for a residual charge. According to said method, the variables of the electrical target charge required for the operation of the method, and the time intervals for the beginning and end of the charging and discharging of the electroactive polymer are determined. The invention also relates to a system for obtaining electrical energy and to a computer program product comprising commands that can be implemented by a microprocessor for carrying out the calculations in the method according to the invention.Type: GrantFiled: June 19, 2010Date of Patent: January 6, 2015Assignee: Bayer MaterialScience AGInventors: Dirk Schapeler, Christian Graf, Jürgen Maas
