T‐800: An 800 Hz Data Glove for Precise Hand Gesture Tracking

SmartBot, EarlyView.
Hand motion capture provides critical insights into human dexterity and facilitates advancements in robotic manipulation, yet existing systems are limited by a trade‐off between temporal resolution and visual occlusion. Here, the authors present T‐800, a high‐bandwidth data glove achieving synchronized full‐hand motion capturing at 800 Hz.

Development of a High-Sensitivity Optical Accelerometer for Low-Frequency Vibration Measurement

Sensors, 2018
Low-frequency vibration is a harmful factor that affects the accuracy of micro/nano-measuring machines. Low-frequency vibration cannot be completely eliminated by passive control methods, such as the use of air-floating platforms.

Construction and Application of Online Vibration Frequency Response Analysis Method for Converter Transformer Winding

High Voltage, EarlyView.
ABSTRACT The harmonic current and vibration of a converter transformer are effective pieces of information for detecting mechanical faults in the winding. In this paper, the ratio of vibration acceleration to the current squared is defined as the vibration frequency response function (VFRF) of the winding, and then, a novel online vibration frequency ...

Dynamic Modal‐Based Vibration Characteristics Analysis and Looseness Fault Diagnosis in Transformer Winding

High Voltage, EarlyView.
ABSTRACT Limited by the theoretical basis and diagnostic methods, the winding mechanical condition monitoring often requires both normal condition vibration signals and present vibration signals, and the winding mechanical condition identification is completed by comparing with the normal condition signals.

Friction and vibration generated during sliding over bare skin correlate with perceived smoothness and moistness

International Journal of Cosmetic Science, EarlyView.
A tactile sensor with a probe replicating a fingerprint quantified skin texture by measuring vibration and friction. Regression analysis linked smoothness and moistness perceptions with high‐frequency vibration amplitude and friction. These findings support the objective assessment of skin texture, enhancing product evaluation consistency and bridging ...
