Personalized Electric Field Cancer Treatment Method and Device Developed

Strategic Insights -

According to a patent filed on November 16, 2022, and published online on October 14, 2025, a team of inventors from South Korea has developed a personalized electric field cancer treatment method and device. This innovative approach aims to improve cancer treatment efficiency by predicting optimal conditions for each patient based on their unique characteristics. The device utilizes a processor, memory, and electric field generator to calculate and correct the electric field strength applied to the tumor region, taking into account patient-specific data, tumor characteristics, and previously input electric field treatment information.

Key Takeaways:

  • The personalized electric field cancer treatment method and device uses a treatment method comprising obtaining patient information, tumor information, and electric field-related information.
  • The patient information includes gender, age, weight, and patient-related information, while the tumor information includes carcinoma information, tumor location information, tumor size information, and tumor-related information.
  • The electric field-related information includes electric field treatment information and electric field system environment information, which are used to calculate and correct the electric field strength applied to the tumor region.
  • The device uses an electric field treatment learning model trained based on historical treatment data comprising patient-specific data, tumor characteristics, and previously input electric field treatment information.
  • The treatment device is equipped with ferroelectric electrodes, an electric field generator, an electric field strength sensor, and a processor, which work together to apply the corrected electric field to the first tumor region according to the determined number, locations, and application time.
  • The device can adapt to different treatment scenarios, including the use or non-use of ferroelectric nanoparticle probes.
  • The personalized approach aims to reduce the quality of life decrease due to increased pain of patients and inconvenience of hospitalization or outpatient treatment.
