Abstract

A transducer apparatus for delivering tumor treating fields to a subject's body, the transducer apparatus including: an array of electrodes, the array configured to be positioned over the subject's body with a front face of the array facing the subject's body, the array comprising electrode elements positioned in existing electrode positions arranged around a centroid of the array; an anisotropic material layer electrically coupled to the array of electrodes and located on a front side of the front face of the array; and at least one void space in the array of electrodes capable of enclosing an areal footprint equivalent to at least a portion of an areal footprint of at least one existing electrode position, and superimposable on at least a portion of at least one existing electrode position by rotation of the array around the centroid.
