The present invention relates to a skin treatment apparatus using plasma. A plasma generator (400) comprises an electrode plate (420), an upper dielectric body (430), independent electrode portions (440) and a lower dielectric body (450). The independent electrode portion is an FPCB or a silver paste positioned a fixed distance away. According to the present invention, the electrode portions each independently work and thus prevent unevenness of plasma and enable the plasma to be generated evenly. According to the present invention, the plasma generator having such configuration is easily formed into a convex shape, and a convex plasma generator is suitable for a curved skin object such as the palm. The convex plasma generator can generate more even plasma and is particularly more effective for a long cylindrical object to be treated, such as the woman's vagina.

Tumor treating fields (TTFields) can be delivered to a subject's body at higher field strengths by switching off one or more electrode elements that are overheating without switching off other electrode elements that are not overheating. This may be accomplished using a plurality of temperature sensors, with each of the temperature sensors positioned to sense the temperature at a respective electrode element; and a plurality of electrically controlled switches, each of which is wired to switch the current to an individual electrode element on or off. A controller input signals from the temperature sensors to determine the temperature at each of the electrode elements, and controls the state of the control input of each of the electrically controlled switches to selectively switch off the current or adjusted the duty cycle at any electrode element that is overheating.

Current cancer treatments such as surgery, radiation and chemotherapy have significant side-effects for the patients. New treatments are being developed to reduce these side-effects while giving doctors alternative methods to treat patients. This invention introduces a new method for treatment of malignant tumors including brain cancer, pancreatic cancer, lung cancer, and ovarian cancer. The method uses low-power RF wave to disrupt and kill cancer cells during mitosis resulting in shrinking the size of solid tumors. Direction of polarization of the electric field of the RF wave relative to the axis of division of the cancer cells has an impact on the ability of the RF wave in disrupting mitosis and killing the cancer cells. Since the orientation of the cancer cells in a tumor are random a method is needed to change the orientation of the applied RF wave spatially with time to maximize elimination of the cancer cells.

A method for preventing cytokine storm by suppressing clonal expansion of hyperactivated lymphocytes in a COVID-19 infected patient. The method includes placing at least four electrodes on skin of the COVID-19 infected patient by putting at least two electrodes at two locations over chest in front of ribcage of the COVID-19 infected patient and putting at least two other electrodes at two locations adjacent to lung tissue of the COVID-19 infected patient and suppressing mitosis of hyperactivated proliferative lymphocytes cells within the lung tissue of the COVID-19 infected patient by electrically stimulating the hyperactivated proliferative lymphocytes. Electrically stimulating the hyperactivated proliferative lymphocytes includes generating an alternating electric field (AEF) within the lung tissue by applying an AC voltage to the at least four electrodes and periodically changing a direction of the generated AEF in a plurality of directions within the lung tissue.
