Physics-Informed Learning Framework for Lower Limb Kinematic Prediction With Sparse Sensors and Its Application in Chronic Stroke

open access: yesIEEE Transactions on Neural Systems and Rehabilitation Engineering
Kinematic evaluation of gait is critical for biomechanical analysis and disease diagnosis. Stroke survivors, due to unilateral motor impairments, often exhibit asymmetric gait patterns, significantly altering lower limb joint kinematics.

Wireless, 3D Optical Sensor Fabricated Using Mechanical Buckling for Navigation and Agriculture Applications

open access: yesAdvanced Materials Technologies, EarlyView.
This study develops a 3D optical sensor formed by mechanical buckling and equipped with wireless communication for navigation. Off‐the‐shelf electronic components are assembled onto a flexible circuit board, followed by mechanical strain‐guiding, facilitating the integration of an out‐of‐plane sensing configuration with a signal processing module. This

Smart Theremin Based on Electromagnetic Metasurfaces for Fine Dual‐Hand Perception

open access: yesAdvanced Optical Materials, EarlyView.
The proposed Meta‐Theremin leverages a frequency‐spatial multiplexing metasurface to enable robust dual‐hand perception by shielding environmental noise and confining EM fields to interaction zones. Its physics‐informed neural network decouples hand‐specific echoes, enhancing accuracy.

Functional range of motion for basic seated activities of daily living tasks

open access: yesFrontiers in Sports and Active Living
IntroductionEfficient performance of activities of daily living (ADLs) requires coordinated movement across multiple upper-limb joints. However, current assessments of joint range of motion (ROM) during ADLs often rely on subjective evaluation and lack ...

Vision‐Assisted Avocado Harvesting with Aerial Bimanual Manipulation

open access: yesAdvanced Robotics Research, EarlyView.
This work outlines the design and implementation of a bimanual aerial robot that employs visual perception and learning to detect, reach, and harvest avocados. A new gripper and fixer arm assembly is used to harvest avocados, while visual perception enables the detection of avocados and estimation of their position and orientation for determining ...
