我们提出并通过实验证明了品质因数超过 10(4) 的柔性一维聚合物光子晶体纳米腔，用于在实验测量值 10(-4) 下精确传感应变。依靠腔体的致密结构和聚合物的低杨氏模量，腔体的位移和施加的力分别估计为0.94 nm和55 nN。这种柔性纳米腔微传感器具有高线性度和重复性。微传感器概念还与液体环境兼容。聚合物微传感器易于制造、灵活性和生物相容性，有望在物理、材料和生命科学领域的微尺度应变和力测量中得到应用。
We propose and experimentally demonstrate flexible one-dimensional polymer photonic crystal nanocavities with quality factors exceeding 10(4) for precision sensing of strain at experimentally measured values of 10(-4). Relying on the cavity's compact structure and polymer's low Young's modulus, the cavity's displacement and the applied force are estimated as 0.94 nm and 55 nN, respectively. This flexible-nanocavity microsensor shows high linearity and repeatability. The microsensor concept is also compatible with liquid environments. The ease of fabrication, flexibility, and biocompatibility of the polymer microsensor promise applications in strain and force measurements at the microscale in the physical, material, and life sciences.
