Abstract

The force governs the physical world. However, revealing the secrets of nature is not a simple matter. Apart from ordinary physical issues, many nonlinear processes (fluid mechanics, electromagnetic problems, etc.) provide more complicated metrix. These eye-catching but complex phenomena are all related to force. Thus, precisely measuring the force is of fundamental importance to unveil the hidden sciences for a wide of applications. However, advanced instrumentations like atomic force microscope (AFM) cannot best fit the sample sizes, and other specifically-developed MEMS/NEMS fail on universal occasions. Here, we present a fiber-integrated force probe using a spring-composed Fabry-Perot cavity for general-use purposes. The force-sensitivity and resolution reach values of 0.43 nm/nN and 35.79 pN, respectively, representing the highest precisions among all fiber-based nanomechanical probes so far. Typically, we use the proposed sensor to preliminarily explore the micro scale nonlinear problems in fluid mechanics. Further customized its geometries and properties, we anticipate the easy-to-use force probe would generate significant impacts for accurate force-detection.
