An Estimation of Error-Free Frequency Response Function from Impact Hammer Testing

open access: yesJSME International Journal Series C, 2004
The spectrum of impulse response signal from the impact hammer testing is widely used to obtain the frequency response function (FRF). However the FRFs obtained from the impact hammer testing have not only leakage errors but also finite record length errors when the record length for the signal processing is not sufficiently long.

FiN‐Kiri: Fabric‐Based Inflatable Kirigami Actuator for Multimodal Soft Robots

open access: yesAdvanced Robotics Research, EarlyView.
This study introduces a type of inflatable fabric‐based kirigami actuator capable of performing bending motion. The actuator is utilized as soft grippers, a crawling robot and a swimming robot. The crawling robot demonstrated extraordinary motion capabilities, such as moving forward, turning and navigating a narrow tunnel.

Thermally Induced Creep and Viscoelastic Behavior of Copper Micropillar Arrays

open access: yesAdvanced Science, EarlyView.
Copper micropillar arrays are fabricated by electrodeposition within through‐glass‐via, and their thermally induced time‐dependent deformation is quantified. Nanoindentation creep, EBSD, and TEM reveal a heat‐treatment‐driven transition between grain‐boundary‐mediated deformation and dislocation‐dominated creep, while Kelvin modeling captures ...
