A tumor treatment field (TTField) can be delivered to the body of a subject at a higher field strength by disconnecting one or more overheated electrode elements without disconnecting other non-overheated electrode elements. This may be accomplished using a plurality of temperature sensors, each positioned to sense a temperature at a respective electrode element, and a plurality of electrically controlled switches, each wired to switch on or off current to a separate electrode element. A controller inputs a signal from the temperature sensor to determine the temperature at each electrode element and to control the state of the control input of each electrically controlled switch to selectively disconnect current or adjust the duty cycle at any overheated electrode element. 通过断开过热的一个或多个电极元件而不断开不过热的其它电极元件，肿瘤治疗场(TTField)可以以较高的场强递送到受试者的身体。这可以使用多个温度传感器和多个电控开关来完成，其中每个温度传感器被定位成感测相应电极元件处的温度，每个电控开关被布线以接通或断开到单独电极元件的电流。控制器从温度传感器输入信号以确定每个电极元件处的温度，并控制每个电控开关的控制输入的状态以选择性地断开电流或调整过热的任何电极元件处的占空比。
