Patent number: 9835696Abstract: A magnetic field sensor includes first and second sensors for detecting first and second magnetic components according to first and second directions. Each sensor includes a flux concentrator including first and second magnetic parts, an air gap between the parts, and a magnetoresistive element in the air gap. Each magnetoresistive element includes a reference layer having a fixed magnetization direction, the fixed magnetization direction of the first and second sensors being substantially identical, and a sensitive layer having a variable magnetization direction, the variable magnetization direction of the first sensor when the first sensor is in a state of rest being substantially identical to the variable magnetization direction of the second sensor when the second sensor is in the state of rest. The air gaps of first and second sensor are oriented parallel to a direction XY which is, at ±15°, the bisector of the first and second directions.Type: GrantFiled: October 16, 2015Date of Patent: December 5, 2017Assignees: COMMISSARIAT À L'ÉNERGIE ATOMIQUE ET AUX ÉNERGIES ALTERNATIVES, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE (CNRS)Inventors: Bernard Dieny, Hélène Joisten, Philippe Sabon

Patent number: 8686818Abstract: A microparticle includes an oblong flexible tail able to propel the microparticle in a solution along a trajectory using beats transverse to the trajectory, the tail including at least one magnetic element such that the magnetic element causes beats of the tail under the action of an external alternating magnetic field non-collinear with the trajectory and a head mechanically connected to a proximal end of the tail. The microparticle includes at least one layer of material formed from one piece and including the tail and the head, the dimensions and/or shape of the head being selected such that the beats of the proximal end of the tail are limited with respect to the beats of the distal end of the tail and such that the head does not perform a complete revolution around an axis parallel to the trajectory under the effect of the external alternating magnetic field.Type: GrantFiled: September 17, 2010Date of Patent: April 1, 2014Assignees: Commissariat a l'energie atomique et aux energies alternatives, Centre National de la Recherche ScientifiqueInventors: Bernard Dieny, Heélène Joisten, Philippe Sabon
