Wearable Bioelectronics for Home‐Based Monitoring and Treatment of Muscle Atrophy

open access: yesAdvanced Science, Volume 12, Issue 33, September 4, 2025.
As an inevitable disease, muscle atrophy has received more attention. Because the factors that induce this disease are diverse, achieving a complete cure is still impossible. Wearable bioelectronics provides a more comfortable, low‐cost, and efficient way of home care for the monitoring and treatment of muscle atrophy. Therefore, this review summarizes

MEMS: The Sensory Nervous System for Embodied AI Robots

open access: yesSmartBot, Volume 1, Issue 3, September 2025.
Embodied AI represents a shift of intelligence from virtual to physical realms, calling for efficient and multimodal perceptual capabilities. This review illustrates how Micro‐Electro‐Mechanical Systems (MEMS) offer miniaturized, low‐power sensors such as those for ranging, inertia, touch, sound and smell, which serve as robotic “sensory organs”.

Ultrasound fundamentals and their clinical implications for interventional cytopathologists

open access: yesCytopathology, Volume 36, Issue 4, Page 356-374, July 2025.
Interventional cytopathologists need to know about ultrasound physics and instrumentation to produce an image that faithfully recreates the lesion discovered by the sonographer and diagnosed by the radiologist. A deep quantitative understanding of physics is not required.
