The present invention provides a sensor and measuring method. The sensor comprises multiple-layer organo-metallic cross-linked polymers forming various superlattice nanostructured biomimetic membranes for sensing Cooper-pair wave transmissions causing intrinsic magnetic flux quantum observed based on a Josephson junction toroidal array and a controllable state-switch valve having a double-pole electron-relay that promoted Cooper pairs coherently transmitting waves in the membranes within and cross the Josephson toroidal junction barriers at zero-bias. The One-Device-Assembly system enables a femto-joule energy consumption for quantum qubits; or acting as an energy storage device that stores energy 1.53 MJ/cm2 for an application in automobile vehicles.
