AB  - This study describes a fabrication method of microsized AgNW patterns based on 
      poly dimethylsiloxane (PDMS) substrate using a poly(p-xylylene) (parylene) 
      stencil technique. Various patterns of AgNW conductive sheets were created on the 
      wafer scale area in the forms of straight and serpentine lines, texts, and 
      symbols, which dimensions ranged from a few tens of micrometers to hundreds of 
      micrometers. We demonstrated the electrical performance of straight line and 
      serpentine line patterned AgNW electrodes when subjected to mechanical strains. 
      The gauge factor and stretchability ranged from 0.5 to 55.2 at 2% uniaxial strain 
      and from 4.7 to 55.7%, respectively, depending on the shapes and structures of 
      the AgNW electrodes. Using the developed AgNW patterning technique, we fabricated 
      strain sensors to detect small body signals epidermally such as hand motion, eye 
      blink and heart rate. Also, tactile sensors were fabricated and exhibited the 
      sensitivity of 3.91 MPa(-1) in the pressure range lower than 50 kPa, and 0.28 
      MPa(-1) in the pressure range greater than 50 kPa up to 1.3 MPa. From these 
      results, we concluded that the proposed technique enables the fabrication of 
      reliable AgNW patterns on wafer-scale PDMS substrate and the potential 
      applications for various flexible electronic devices.
