  • Publication number: 20250108227
    Abstract: Alternating electric fields (e.g., Tumor Treating Fields or TTFields) can be applied to a subject's body using an apparatus (e.g., a transducer array) that includes a first PCB that has metal pads for coupling an AC signal into the subject's body at high currents, and a second, less expensive PCB that can only handle lower currents. The first PCB is located at a central portion of the apparatus, and the second PCB is located at a peripheral portion of the apparatus. Temperature sensors (e.g., thermistors) are electrically connected to the second PCB. In some embodiments, the second PCB is significantly larger than the first PCB.
