Abstract: Disclosed herein are systems, devices, and methods for better conforming to biological tissue, reducing the temperature and irritation of tissue, modulating tissue, and/or wirelessly sending and receiving power through tissue. Devices can include panels movable with respect to each other to allow the body to move between a flattened and non-flattened state. Devices can include movable parts or structures that enable improved conformance to three-dimensional surfaces of tissue.
