I'm working on a project to create a device which emits pulsed electric fields that will then be used to investigate its benefit in skin disorders. The investigation would consist of placing the device close to the skin area in question and it would then be "bathed" with a pulsed electric field.
I've read that the simplest way to achieve this is to connect the pulse generator to various electrode plates. But it raised me a lot of questions. How would an electric field be produced between the electrode and the skin? Perhaps I should be asking, how is the electric field emitted from the electrode into the skin? Would the skin (i.e. person) "behave" as the lower plate of a capacitor, thus forming a closed circuit?
Going back to the circuitry, I reckon the output impedance should be very high as well to avoid unwanted large currents. The skin area needs to be "bathed" uniformly too. How can this be best achieved? Would the shape of the electrodes matter? Could the electrodes be as simple as a metal plate?
Looking forward to hearing from you.
