The Experiment and Simulation Method to Calibrate the Shear Modulus of Individual ZnO Nanorod

Abstract

A general method is presented to directly measure the shear modulus of an individual nanorod using atomic force microscope (AFM). To obtain shear modulus with less experiment error, finite element simulation is employed to simulate the twisting process of a ZnO nanorod. Based on the experimental measurements, the shear modulus of ZnO nanorod with 4 µm in length and 166 nm in radius is characterized to be 9.1 ± 0.2 GPa, which is obviously more accurate than the simple averaged experimental result.

Recent advances in MXene-based force sensors: a mini-review

“…Sensitivity, sensing range, and response time are the core performance of the force sensor, which determines the minimum induction limit, sensing speed and maximum strength bearing limit of the sensor to detect external strain. 6,[46][47][48][49] Sensitivity, also known as gauge factor (GF), is expressed by the slope of the relative change of the resistance or capacitance signal to the external strain of the sensor during its operation. 33 For resistive sensors, GF is denoted as…”
