In article number 1703964 , Guang‐Zhong Yang and co‐workers use light from a single mode optical fiber to interrogate the integrated sensor of a compliant microgripper. An applied force results in the spacing of the thin‐layer features to change and, hence, vary the interference pattern. The spectrum of the light reflected back along the fiber can then be used to determine applied force.
