Methods, systems, and apparatuses for combined tumor treating fields and mental health therapy

A method comprising:

• causing, based on a time interval, cyclical application of a first electric field in a first direction via a first transducer array comprising a first plurality of electrodes and a second electric field in a second direction, opposite the first direction, via a second transducer array comprising a second plurality of electrodes, wherein the first electric field and the second electric field are at a first frequency, wherein each electrode of the first plurality of electrodes and each electrode of the second plurality of electrodes comprises a first material with a resonant frequency associated with the first frequency and a second material with a resonant frequency associated with a second frequency;
• and
• causing, based on the time interval, cyclical application of a third electric field in a third direction via a third transducer array comprising a third plurality of electrodes and a fourth electric field in a fourth direction, opposite the third direction, via a fourth transducer array comprising a fourth plurality of electrodes, wherein each electrode of the third plurality of electrodes and each electrode of the fourth plurality of electrodes comprises the first material with the resonant frequency associated with the first frequency and the second material with the resonant frequency associated with the second frequency, and wherein the third electric field and the fourth electric field are at the second frequency.
