An Acceleration Sensing Method Based on the Mode Localization of Weakly Coupled Resonators
TL;DR: In this paper, an acceleration sensing method based on two weakly coupled resonators (WCRs) using the phenomenon of mode localization was reported. But the proposed mode localization with the differential perturbation method leads to a sensitivity enhancement of a factor of 2 than the common single perturbations method.
Journal ArticleDOI
A Handheld Inertial Pedestrian Navigation System With Accurate Step Modes and Device Poses Recognition
TL;DR: A multiple classifier is developed to recognize human step modes and device poses and a novel step detection model is created based on the results of the classifier to eliminate the over-counting and under- Counting errors.
Journal ArticleDOI
A High-Sensitivity Micromechanical Electrometer Based on Mode Localization of Two Degree-of-Freedom Weakly Coupled Resonators
TL;DR: In this paper, a high-sensitivity resonant electrometer based on the mode localization of two degree-of-freedom weakly coupled resonators (WCRs) is reported.
Journal ArticleDOI
Progressive contact-separate triboelectric nanogenerator based on conductive polyurethane foam regulated with a Bennet doubler conditioning circuit
TL;DR: In this paper, a progressive triboelectric nanogenerator based on macro-triangle-prism-shaped conductive polyurethane (PU) foam and polytetrafluoroethylene (PTFE) film was proposed.
Journal ArticleDOI
