A neuromodulation device comprising: electrically conductive coils arranged in an array; and circuitry coupled to energize the coils in the array using current pulses that generate an electromagnetic field, the circuitry configured to control one or more parameters of the current pulses, including at least amplitude and phase of the current pulses, such that the electromagnetic field undergoes constructive and destructive interference that focuses and/or steers a magnetic flux density within a region of interest of a patient, whereby the neuromodulation device further comprises a substrate to be applied to the patient and whereby each of the coils comprises a plurality of elastic members, characterised in that the plurality of elastic members comprises: a first elastic member comprising a first anchor portion attached to the substrate and a first free portion; and a second elastic member comprising a second anchor portion attached to the substrate and a second free portion, wherein a stress profile in the first elastic member biases the first free portion to curl away from the substrate and a stress profile in the second elastic member biases the second free portion to curl away from the substrate, wherein the first anchor portion and the second anchor portion are connected at a contact portion and wherein the stress profiles and the contact portion are chosen so that the first elastic member and the second elastic member together form a winding of the coil. electrically conductive coils arranged in an array; and circuitry coupled to energize the coils in the array using current pulses that generate an electromagnetic field, the circuitry configured to control one or more parameters of the current pulses, including at least amplitude and phase of the current pulses, such that the electromagnetic field undergoes constructive and destructive interference that focuses and/or steers a magnetic flux density within a region of interest of a patient, whereby the neuromodulation device further comprises a substrate to be applied to the patient and whereby each of the coils comprises a plurality of elastic members, characterised in that the plurality of elastic members comprises: a first elastic member comprising a first anchor portion attached to the substrate and a first free portion; and a second elastic member comprising a second anchor portion attached to the substrate and a second free portion, wherein a stress profile in the first elastic member biases the first free portion to curl away from the substrate and a stress profile in the second elastic member biases the second free portion to curl away from the substrate, wherein the first anchor portion and the second anchor portion are connected at a contact portion and wherein the stress profiles and the contact portion are chosen so that the first elastic member and the second elastic member together form a winding of the coil. a first elastic member comprising a first anchor portion attached to the substrate and a first free portion; and a second elastic member comprising a second anchor portion attached to the substrate and a second free portion, wherein a stress profile in the first elastic member biases the first free portion to curl away from the substrate and a stress profile in the second elastic member biases the second free portion to curl away from the substrate, wherein the first anchor portion and the second anchor portion are connected at a contact portion and wherein the stress profiles and the contact portion are chosen so that the first elastic member and the second elastic member together form a winding of the coil.
