A recently granted patent (Publication Number: US11883652B2) discloses an apparatus designed to impose electric fields through a target region in a patient's body. The apparatus includes a transducer array with multiple electrode elements for placement on the patient's body to provide TTFields through an alternating current waveform. A sensor array with temperature sensors is positioned near the electrode elements, connected to conductors for measuring temperature changes. A circuit provides a known amount of electricity to a temperature sensor, obtaining a corresponding electrical reading, which is used by a controller to adjust the alternating current waveform based on the temperature reading.

Furthermore, the apparatus includes a current source, multiplexers, and controllers to manage the flow of electricity to the temperature sensors. The circuit utilizes analog to digital converters, buffers, and amplifiers to process temperature readings effectively. The patent also details methods for selectively activating temperature sensors and adjusting the alternating current waveform based on temperature readings. Overall, the apparatus and method described in the patent aim to enhance the precision and effectiveness of imposing electric fields in a patient's body for therapeutic purposes.
