Metal thin films on soft polymers provide a unique opportunity for resistance-based strain sensors. A mechanical mismatch between the conductive film and flexible substrate causes cracks to open close, changing electrical resistance as function of strain. However, very randomness formation, shape, length, orientation, distance adjacent limits sensing range well repeatability. Herein, we present breakthrough: Zerogap sensor (ZSS), whereby lithography eliminates violent tearing process inherent in conventional crack sensors allows short periodicity gaps with gentle sidewall contacts, critical high enabling operation over an unprecedentedly wide range. Our achieves gauge factor 15,000 at external εext = 18%, highest known value. With uniform four-to-ten thousand nanometer widths characterized by strain, this approach has far reaching implications future whose is limited only that substrate, non-violent operations always remain below tensile limit metal.
