Nanorobotic System iTRo for Controllable 1D Micro/nano Material Twisting Test

Abstract In-situ micro/nano characterization is an indispensable methodology for material research. However, the precise in-situ SEM twisting of 1D material with large range is still challenge for current techniques, mainly due to the testing device’s large size and the misalignment between specimen...
