AB  - Recently, mechanical strain sensors have been extensively developed to quantify 
      large mechanical deformations for stretchable and wearable applications. In this 
      study, we propose a plasmonic strain sensor based on the mechanical control of 
      optical properties using an assembled film comprising In(2)O(3): Sn nanoparticles 
      (ITO NP film). The resonant reflectance in the infrared range could effectively 
      be tuned by applying strain to the ITO NP film deposited on an elastomeric 
      polydimethylsiloxane (PDMS) sheet. The change in reflectance was caused by the 
      mechanical deformation of the PDMS sheet. The operating mechanism of the proposed 
      plasmonic strain sensor was related to anisotropic fragments induced by cracks 
      formed perpendicular to the direction of the applied strain. These anisotropic 
      fragments were functionalized as optical modulators to change the reflectance 
      depending on the applied strain. The sensing performance of the proposed 
      plasmonic strain sensor was evaluated by using a PDMS sheet with a circular hole 
      that produced nonuniform stress distributions. Finally, to evaluate the flexible 
      and wearable performance of the proposed sensor, the optical detection of human 
      motion was performed by detecting joint-related movements. The optical detection 
      of human motion could be achieved because a change in motion (e.g., bending and 
      stretching of the index finger) was reversibly associated with reflectance 
      changes. Therefore, this study provides new insights into plasmon-based strain 
      sensing for various applications in flexible instruments and human motion 
      detection.
