A reconfigurable material system comprising an aggregate of a plurality of identical modular robotic unit cells. Each unit cell includes a rigid geometric chassis, an onboard processing element configured for distributed coordination with adjacent unit cells, and multiple electrostatic coupling interfaces disposed on exterior surfaces of the chassis. The unit cells are operable in a first configuration in which the electrostatic coupling interfaces are inactive, allowing relative movement and rearrangement of the unit cells within a workspace. In a second configuration, selective activation of the electrostatic coupling interfaces causes adjacent unit cells to adhere and align, forming a mechanically coherent aggregate structure. By coordinating activation and deactivation of the electrostatic coupling interfaces across the plurality of unit cells, the system enables controlled transitions between a reconfigurable state and a load-bearing assembled state.

This invention discloses an electrostatic coupling capacitance sensor, an electrostatic coupling capacitance sensing measurement system, and a measurement method. The electrostatic coupling capacitance sensor includes a working electrode, a protective electrode, and a shielding layer. The protective electrode is disposed within the shielding layer through an insulating layer, and the working electrode is disposed within the protective electrode through an insulating layer.
