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.

Sleep and cardiac autonomic modulation in older adults: Insights from an at‐home study with auditory deep sleep stimulation

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary The autonomic nervous system regulates cardiovascular activity during sleep, likely impacting cardiovascular health. Aging, a primary cardiovascular risk factor, is associated with cardiac autonomic disbalance and diminished sleep slow waves. Therefore, slow waves may be linked to aging, autonomic activity and cardiovascular health. However, it

Association Between Sleep Quality and Oxidative Stress in Postoperative Cardiovascular Patients—A Pilot Study

Journal of Sleep Research, EarlyView.
In 15 postoperative cardiac surgery patients, venous reactive oxygen species (ROS) measured by electron spin resonance (ESR) over 48 h showed no consistent circadian pattern. Higher ROS was associated with lower subjective sleep efficiency and more nocturnal awakenings, but not with other sleep measures.

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.
