A modular deformable electronics platform is attachable to a deformable surface, such as skin. The platform is tolerant to surface deformation and motion, can flex in and out of a plane of the platform without hindering operability of electrical components included on the platform, and is formed via arrangement of discrete flexible tiles, with corners of adjacent tiles connected by a flexible connection material so that individual tiles can translate and rotate relative to each other. Interconnects disposed on bases of separate tiles electrically connect adjacent tiles via their connected corners, and electrically connect components disposed on different tiles. Each pair of adjacent corner connections defines an axis about which at least a portion of the platform can flex without deformation and without hindering connections between tiles. The flexible material and/or bases of the tiles can include Parylene.
