Patent number: 9647578Abstract: An energy harvester having a converter suitable for converting a variation of the energy to be harvested into a corresponding excess of electrical charges. There is a circuit for collecting the excess of electrical charges, the circuit is equipped with a controllable switch and a control device for the switch designed to control the switching of this switch to its closed position. The control device is suitable for exerting a force which stresses the electrical contacts towards one another. The force varies continually as a function of the quantity of electrical charges present on the first terminal and bringing the electrical contacts to bear on one another only when the excess of electrical charges exceeds a predetermined threshold, and/or for ionizing the electrically insulating medium to produce an electrical arc between the two electrical contacts only when the excess of electrical charges exceeds the predetermined threshold.Type: GrantFiled: October 15, 2013Date of Patent: May 9, 2017Assignees: COMMISSARIAT À L'ÉNERGIE ATOMIQUE ET AUX ÉNERGIES ALTERNATIVES, INSTITUT POLYTECHNIQUE DE GRENOBLE, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUEInventors: Jérome Delamare, Bernard Viala, Orphée Cugat, Thibault Ricart
