## Description

- description: Organic semiconductor (OSC) single crystals feature flexibility, solution
    processability, and high-mobility coherent carrier transport, which are advantageous
    for printed flexible electronic applications. A mechanical strain sensor is a
    target device whose high sensitivity and wide measurement range have been demonstrated
    when OSC single crystals were employed as the active channel. However, there have
    been limited reports on scalable fabrication of devices and reliable measurements,
    which limits the use of strain sensors in a wide range of applications. In this
    study, we present a comprehensive approach to address these issues through advanced
    device processing, design, and measurements. Our resistive strain sensors showed
    a small drift owing to the stable and effective p-type chemical doping of the
    OSC single crystals. A Wheatstone bridge circuit and compact lock-in amplifier
    were designed to accurately measure resistance changes at low noise levels. The
    experimental results demonstrated a substantial reduction in noise and achieved
    high-precision measurements with precision of ±1.8 ppm.
