Abstract: Provided herein are devices, systems, and methods for monitoring lesion or treated area in a tissue during focal ablation or cell membrane disruption therapy. Provided herein are embodiments of an electrical conductivity sensor having an impedance sensor, where the impedance sensor can be configured to measure a low-frequency and a high-frequency impedance and a substrate, where the impedance sensor is coupled to the substrate. The substrate can be flexible. In embodiments, the impedance sensor can contain two or more electrical conductors. The electrical conductors can be in a bipolar configuration. The electrical conductors can be in a tetrapolar configuration. In embodiments, the electrical conductivity sensor can have two impedance sensors that can be coupled to the substrate such that they are orthogonal to each other.
