1. A transducer array, comprising:
a conductive layer having one or more electrode element, the one or more electrode element configured to receive electrical signals from an electric field generator producing an electric signal as a Tumor Treating Field; and
a conductive gel layer overlapping the one or more electrode element of the conductive layer, the conductive gel layer having a first region and a second region, the first region having a first thickness and a first resistance and the second region having a second thickness and a second resistance, the first thickness being different from the second thickness.
