1. A system for locating electrodes on a head of a user comprising a headset comprising:
a set of electrode bodies configured to detect electroencephalographic signals from the head of the user; and
a set of spring elements:
interconnecting and configured to elastically locate the set of electrode bodies on the head of the user;
configured to elastically deform to accommodate a size of the head of the user; and
comprising a first spring element:
coupling a first electrode body of the set of electrode bodies to a second electrode body of the set of electrode bodies;
characterized by a first spring rate; and
comprising:
first spine comprising:
 a first spring segment; and
 a second spring segment cooperating with the first spring segment to define a first serpentine geometry comprising an even quantity of loops;
a first flexible circuit board comprising:
 a first circuit board segment arranged along a first side of the first spring segment; and
 a second circuit board segment arranged along a second side of the second spring segment; and
conductive transfer element:
 electronically interposed between the first circuit board segment and the second circuit board segment;
 extending over an edge of the first spine; and
 extending between the first side of the first spring segment and the second side of the second spring segment; and
a second spring element:
coupling the first electrode body to the third electrode body;
characterized by a second spring rate less than the first spring rate;
comprising:
 a second spine defining a second serpentine geometry comprising an odd quantity of loops; and
 a second flexible circuit board arranged along a first side of the second spring; and
 cooperating with the first spring element to maintain relative positions of the first electrode body, the second to an electroencephalography standard.
