Wireless Power Transfer Modalities for Implantable Bioelectronics: Electromagnetic, Acoustic, and Magneto‐Dynamic Perspectives

open access: yesAdvanced Materials Technologies, EarlyView.
This review traces the evolution of wireless power transfer (WPT) for implantable medical devices, spanning electromagnetic, magnetoelectric, acoustic, and magneto‐dynamic systems. Quantitative comparisons of power, distance, and device scale highlight trade‐offs across modalities, while emerging hybrid mechanisms reveal strategies to overcome ...

Unilateral Ankle‐Foot Exoneuromusculoskeleton with Balance‐Sensing Feedback for Self‐Help Telerehabilitation after Stroke

open access: yesAdvanced Robotics Research, EarlyView.
This study introduces a hybrid robot that integrates mechanical assistance by musculoskeletons (i.e., soft pneumatic muscle with rigid exoskeletal extensions), neuromuscular electrical stimulation, and vibrotactile feedback in a lightweight wearable mechatronic complex applicable to the paretic ankle–foot poststroke for gait restoration. The system can

The impact of peripheral arterial disease on patients with mechanical circulatory support. [PDF]

open access: yes, 2020
Background: Left ventricular assist devices (LVAD) are indicated as bridging or destination therapy for patients with advanced (Stage D) heart failure and reduced ejection fraction (HFrEF). Due to the clustering of the mutual risk factors, HFrEF patients

Interactions of Interaural Time and Level Differences in Spatial Hearing with Cochlear Implants

open access: yesAdvanced Science, EarlyView.
Differences in timing (ΔT) are weighted heavily compared to differences in loudness (ΔL) in binaural hearing with cochlear implants. Abstract Normally hearing humans can localize sound sources quite accurately, with minimum audible angles as small as 1°. To achieve this, these auditory pathways combine information from multiple acoustic cues, including
